Virtual reality (“VR”) and augmented reality (“AR”) technologies are rapidly maturing.  Companies like Facebook and Microsoft are capitalizing on these technologies and actively releasing products to consumers.  Both companies’ products blur the line between the real world and the virtual world.  The blurring of this line presents novel questions regarding the protection of digital intellectual property that exists solely within the virtual world.

One such question is whether design patent protection will be available to three-dimensional digital models, models of real-world items that are digitally reproduced in the virtual world.  To receive design patent protection, 35 U.S.C. § 171 requires, inter alia, that the subject matter be an “article of manufacture.”  Based on existing precedent from the U.S. Court of Appeals for the Federal Circuit, it appears the court is reluctant to expand design patent protection to three-dimensional digital models.

This Comment argues that the apparent reluctance of the Federal Circuit to expand intellectual property protections to three-dimensional digital models, as signaled in its recent decisions in In re Nuijten and ClearCorrect Operating, LLC v. International Trade Commission, is at odds with design patent’s § 171.  This Comment analyzes § 171 and its broad interpretation by the Federal Circuit’s predecessor, the Court of Customs and Patent Appeals (CCPA).  After, the Comment contends that the Federal Circuit’s current trend deviates from the CCPA’s precedent and argues that the court should return to the broad interpretation of § 171.  This broad interpretation would provide design patent protection to three-dimensional digital models present in VR and AR worlds.


“What is real?  How do you define ‘real’?  If you’re talking about what you can feel, what you can smell, what you can taste and see, then ‘real’ is simply electrical signals interpreted by your brain.” [1]

Given the explosion of virtual reality (“VR”), an environment where the real world is replaced with a virtual one, and augmented reality (“AR”), an environment where the real world is supplemented by computer-generated input,[2] this once futuristic quote from The Matrix has become more relevant today.  These technologies are available to consumers through a variety of gadgets, ranging from high-end headsets, such as the Oculus Rift,[3] to more common products, such as a smartphone screen and camera that are used in Pokémon Go.[4]  These technologies seek to immerse the user in a virtual reality, seamlessly merging the real and electronic worlds.[5]  As touted by most manufacturers of VR and AR technology, this technology provides a new canvas for movies, video games, and advertisers.[6]  Content developers create these worlds using three-dimensional models, which are computer-programmed models that mimic items in our world.[7]  Once the technology matures, the line between the physical world and the virtual world may seemingly disappear.[8]  As this line disappears, it may become impossible to distinguish a physical object from a virtual three-dimensional digital model placed right next to it.[9]

Unsurprisingly, the explosion of these technologies presents new challenges and questions regarding intellectual property rights.[10]  One question involving the interaction between intellectual property and the VR and AR worlds is whether a three-dimensional digital model will meet the statutory requirements for a design patent, which protects the aesthetic appearance of a functional item.[11]  In recent years, design patents have grown in value, making them important parts of an intellectual property portfolio.[12]  As the use of VR and AR continues to grow, individuals and businesses will likely seek to use such patents to protect the three-dimensional digital models used in these worlds.

Although the need for design patent protection of three-dimensional models has grown, design patent protection for the models has an uncertain legal future.  Congress last updated the design patent statute in 1952 when it amended 35 U.S.C. § 171 to grant a design patent to “[w]hoever invents any new, original and ornamental design for an article of manufacture.”[13]  Thus, to receive a design patent, the design must be “for an article of manufacture.”[14]  As written, the scope of the article of manufacture requirement is unclear, but throughout the twentieth century, courts were willing to interpret the requirement fairly broadly.[15]  However, the U.S. Court of Appeals for the Federal Circuit recently articulated a narrower view, first when applying the requirement to electronic and digital technologies,[16] and next when interpreting article of manufacture requirements in statutes akin to § 171.[17]

This Comment argues that as VR and AR technologies develop, the Federal Circuit and the U.S. Patent and Trademark Office (USPTO) should interpret the design patent subject matter protection statute broadly, incorporating three-dimensional digital models into its scope.  Part I provides background, surveying the history and current state of the art of VR and AR technologies, and reviews the USPTO’s and the courts’ interpretations of § 171 of the design patent statute.  Part II then argues that courts should apply a broad interpretation of the article of manufacture requirement as adopted by the U.S. Court of Customs and Patents Appeals (CCPA), and that the Federal Circuit improperly narrowed the scope of an “article of manufacture” when it applied the requirement to three-dimensional digital models.

I.  Virtual and Augmented Reality: Its Roots, Its Current State, and the Treatment of Similar Technologies in Court

The recent advancement of VR and AR has put these technologies on a collision course with design patent law.  VR and AR technologies were created in the mid-twentieth century and are just reaching maturity today.[18]  In contrast, Congress first created design patent protection in the mid-nineteenth century.[19]  As design patent law developed, courts initially maintained an inclusive view of the subject matter the design patent statute protected.[20]  Recently, however, the Federal Circuit has begun to narrow what subject matter may be protected.[21]

A.  An Overview of Virtual and Augmented Reality

Understanding the challenges surrounding VR and AR technologies and intellectual property rights requires understanding the technology itself, especially its history and the current state of the virtual and augmented art.

1.  A brief history of virtual and augmented reality

Depending on how virtual and augmented reality are defined, the two have a surprisingly long history.[22]  In the 1950s and 1960s, inventors launched various digital and electronic technologies that established the VR world, including both commercial and defense technologies.[23]

In the commercial realm, inventors created entertainment technologies to rudimentarily stimulate the user’s senses—sight, sound, smell, and touch.[24]  In the defense realm, Air Force-funded research improved flight simulators, moving beyond solely mechanical simulations and adding a digital-visual component.[25]

As computer-based technology became more affordable to consumers in the 1970s and 1980s, video games exploded in the personal entertainment industry.[26]  During this period, video game systems shifted away from the large machines found in arcades towards smaller consoles used in the comfort of one’s home.[27]  The electronics industry’s shift from command line prompt control of computers to graphical user interface control resulted in the wider availability of video games.[28]  As the graphical display trend continued, the next step for the video game industry was moving from a screen to a fully-immersed VR video game experience.[29]

Personal entertainment companies championed the quest to craft technology that could provide VR products for consumers.[30]  Despite the trend towards in-home video game consoles, video game companies began investing in research and development to create both arcade-based and personal VR video game equipment.[31]  In the early 1990s, companies such as Nintendo and Sega created VR-based video games for use outside of the arcade.[32]  However, because of technological shortcomings, the systems of the 1990s were never commercially successful; the graphical display systems of the products did not create the immersive experience that developers promised.[33]  Specifically, the graphic systems, consisting of crude three-dimensional digital models, failed to simulate actual, real-world environments.[34]  This failure caused the boom of the VR market in the 1990s to quickly bust, pushing the technology out of the personal entertainment industry’s spotlight.[35]  The graphic systems that remedied the issues of the technology and enabled VR success became available in the 2000s.[36]  These systems create the realistic environments that developers originally promised.[37]

2.  The current state of the art

In the past five years, developers have made new strides in VR and AR technology.[38]  Inventors have remedied the issues that plagued the technologies in the 1980s and 1990s—mainly the poor graphical representation of three-dimensional models—through advancements in three-dimensional graphic systems.[39]  The reemergence of the technology has led to investments from the biggest consumer electronic companies, including Facebook, Microsoft, and Sony.[40]

The Oculus Rift is setting the technological benchmark for the VR industry.[41]  Facebook purchased Oculus Rift for $2 billion in 2014, signaling that the social media company believed VR was ready for a return to the consumer electronic spotlight.[42]  One of the main reasons for the publicity surrounding the Oculus Rift is that, for the first time in VR history, a unit is delivering “presence”—the feeling that the user is fully immersed in the virtual world.[43]  By creating presence, VR technology allows users to interact with a world where the three-dimensional models programmed into the system match those that users come across every day.[44]  Such virtual interactions can also allow the users to interact with items they would never come across, including luxury automobiles and militaristic weapons.[45]

While Facebook has targeted the VR market, Microsoft has targeted VR’s sister, AR.[46]  Microsoft’s flagship AR product, the HoloLens, promises to merge the actual and virtual worlds into one.[47]  Because the HoloLens technology actually augments the user’s perception of the real world, users are able to interact with digital models as if the model was on the workspace in front of them.[48]  Other applications of the technology include a virtual-world television screen to watch a movie, or a virtual model of furniture to better imagine how the real-world product would fit in a living room.[49]  As these examples illustrate, the technology’s goal is to fully integrate virtual and physical reality.

VR and AR stand on the cusp of pushing the world into a new technological frontier, blurring the lines between the physical and virtual worlds.[50]  Consequently, they present new questions within intellectual property law, such as whether intellectual property protection should extend to three-dimensional digital models.[51]

B.  An Overview of Design Patent Protection

A design patent is only one form of federal protection for intellectual property.  Federal law protects several forms of intellectual property:  copyrights, trademarks, trade secrets, and patents.[52]  A copyright protects an author’s or artist’s work,[53] a trademark protects a company’s image in commerce,[54] a trade secret protects a company’s secret device or manufacturing process,[55] and a patent protects an invention.[56]  On their edges, these bodies of law interact and overlap with each other.[57]

When issuing a patent, the federal government grants the inventors a property right in their inventions.[58]  This property right grants the right to exclude others from “making, using, offering for sale, selling or importing the invention[]” within the United States, or importing the invention into the United States.[59]  The USPTO is statutorily authorized to issue three types of patents: (1) utility patents, (2) design patents, and (3) plant patents.[60]  The most common type of patent is a utility patent, which is granted for novel, useful, and nonobvious inventions.[61]  In contrast, a design patent is granted for “any new, original and ornamental design for an article of manufacture.”[62]  The third type of patent, a plant patent, is of much more limited use in that it is granted to anyone who “invents or discovers and asexually reproduces any distinct and new variety of plant.”[63]

There are key differences between a utility patent and a design patent.  First, a utility patent protects the way an article—the subject matter of the invention or design—functions; a design patent protects an article’s aesthetic appearance.[64]  Second, the term of a utility patent is twenty years, while the term of a design patent is fourteen or fifteen years.[65]  Third, although an inventor can file multiple claims within a utility patent application, a design patent application may only contain one claim.[66]  Finally, the pendency of the prosecution for a utility patent is typically between twenty-five and twenty-eight months,[67] and the pendency of the prosecution for a design patent is typically between seventeen and twenty months;[68] therefore, the pendency of a typical design patent is six months to a year shorter than that of a utility patent.  Despite being less common than a utility patent, the design patent is gaining popularity and proving to be just as valuable in an intellectual property portfolio.[69]

Rather than protect the article itself, a design patent protects the design “embodied in or applied to an article”; in other words, a design patent protects the article’s aesthetic appearance.[70]  Because copyright protection is not available for useful articles, Congress passed design patent legislation to fill the gap between the copyright protection available to artists and the patent protection available to inventors.[71]  Accordingly, design patents protect the creative or aesthetic features of a utilitarian product.[72]  As a result, a designer[73] theoretically could protect the same design by both copyright and design patent law.[74]  However, because the owner of a design patent is granted an absolute right to exclude for a period of fourteen years, Congress created strict statutory requirements to receive a design patent grant from the USPTO.[75]

1.  A design patent claim

Unlike utility patents, which may contain multiple claimed inventions, the USPTO restricts a design patent to a single claimed design.[76]  Every patent application, utility or design, includes claims, which establish the metes and bounds of the property right granted in the patent.[77]  A patent grants the right to exclude others from infringing on the enumerated claims.[78]  Unlike a utility patent, which describes the claimed invention in words, a design patent describes the claimed property right through drawings.[79]  Upon filing an application at the USPTO, the designer must submit enough views of the design to create “a complete disclosure” of the design’s appearance.[80]  As seen in the examples below, the solid lines of a design patent claim constitute the actual ornamental aspects of the claimed design, while the dashed lines show the surrounding environment, which is not part of the designer’s claim.[81]

Designs for both the early version of the iconic Coca-Cola bottle (Figure 1) and the Nintendo Game Boy (Figure 2) include only solid lines; therefore, the patents claimed the entire ornamental design of the bottle and the game.  A third example is the design of a pair of Oakley sunglasses (Figure 3), which exemplifies the interplay of the solid and dashed lines to show what is and is not claimed by the designer.

Figure 1:  Coca-Cola Bottle Design Patent Claim[82]

Figure 2:  Nintendo Game Boy Design Patent Claim[83]

Figure 3:  Oakley Sunglasses Design Patent Claim[84]

Upon submission of a design patent application, the USPTO spends seventeen to twenty months examining the submitted application to ensure compliance with statutory requirements, including § 171.[85]

2.  Statutory requirements to receive a design patent

A designer must satisfy four requirements prior to receiving a design patent from the USPTO:  the design must be (1) novel, (2) nonobvious, (3) ornamental, and (4) an article of manufacture.[86]  These statutory requirements are outlined in 35 U.S.C. § 171, which reads, “Whoever invents any new, original and ornamental design for an article of manufacture may obtain a patent therefor, subject to the conditions and requirements of this title.”[87]  Because § 171 is subject to the “conditions and requirements” of Title 35 of the U.S. Code, the Federal Circuit has looked to other sections of that title, such as § 102 and § 103, to interpret its scope.[88]

a.  The relationship between 35 U.S.C. § 101 and § 171

Within Title 35 of the U.S. Code, § 171 for design patents is analogous to § 101, which defines the patentable subject matter for a utility patent.[89]  Section 101 reads, “Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.”[90]

Section 171 differs in two ways from the statutory requirements to receive a utility patent under § 101.  First, § 171 does not use the word “useful,” and second, § 171 includes the word “original” to distinguish a design from a utility patent.[91]  In its analysis of the overall structure of the design patent statutory scheme, the Federal Circuit has explained that the “newness” and “originality” requirements of § 171 import the requirements of § 102 (novelty) and § 103 (nonobviousness) because § 171 states that the statutory provision is subject to the “conditions and requirements of this title.”[92]

b.  The novelty, nonobvious, and ornamentality requirements of § 171

Given this relationship between § 171 and § 101, the first three requirements for design patents are relatively straightforward.  First, § 171 requires that the claimed design is novel, which means that no prior art discloses the same design.[93]  Prior art is the collection of previous designs known to the public as defined by § 102.[94]  In Gorham Co. v. White,[95] the Supreme Court outlined the test for design novelty—the “ordinary observer” test.[96]  This test finds a design anticipated, or not novel, if an “ordinary observer” could mistake that design with another design that preceded it.[97]

Second, courts interpret § 171 to require that the design is nonobvious, which designers establish by exercising “inventive or originative faculty.”[98]  In International Seaway Trading Corp. v. Walgreens Corp.,[99] the Federal Circuit outlined the two-pronged test for nonobviousness.[100]  In the first prong, one having “ordinary skill in the art”[101] determines “whether to combine earlier [prior art] references to arrive at a single piece of art for comparison with the potential design or to modify a single prior art reference.”[102]  After establishing this reference, the finder-of-fact applies the second prong by using novelty’s “ordinary observer” test to compare the formulated reference from the first prong to the design seeking patent protection.[103]  In other words, after one having ordinary skill in the art establishes an objective prior art reference, the finder-of-fact determines whether an “ordinary observer” would find the formulated design substantially similar to the design seeking protection; if they are found similar, then the design is obvious and thus not patentable.[104]

Third, the claimed design meets the ornamentality requirement when it creates “a more pleasing experience” than the prior art.[105]  In Bonito Boats, Inc. v. Thunder Craft Boats, Inc.,[106] the Supreme Court explained that “a design must present an aesthetically pleasing appearance that is not dictated by function alone.”[107]  Therefore, some measure of pleasing appearance is required to receive a design patent.[108]  The scope of § 171’s final requirement, however, is not so clear.

C.  The Design Patent Article of Manufacture Requirement of § 171

The final requirement to receive a design patent is that the design is “for an article of manufacture.”[109]  Over time, Congress has modified the text of this requirement within the design patent statute, and the courts have expanded their interpretation.[110]

1.  The changing language of § 171

The article of manufacture requirement has been part of the statute since its initial passage.[111]  However, through various revisions, Congress simplified the text of the requirement.  When originally enacted in 1842, the design patent statute granted design patents for the following categories:

[(1)] any . . . design for a manufacture, whether of metal or other material or materials, . . . [(2)] design for the printing of woollen, silk, cotton, or other fabrics, . . . [(3)] design for a bust, statute, or bas relief or composition in alto or basso relievo, or [(4)] any . . . impression or ornament, or . . . [(5)] any . . . pattern, or print, or picture, to be either worked into or worked on, or printed or painted or cast or otherwise fixed on, any article of manufacture, or [(6)] any . . . shape or configuration of any article of manufacture not known or used by others . . . .[112]

Subsequently, Congress revised the statute in 1870 to include the following subject matters:

[(1)] design for a manufacture, bust, statue, alto-relievo, or bas-relief; . . . [(2)] design for the printing of wool[l]en, silk, cotton, or other fabrics; . . . [(3)] impression, ornament, pattern print, or picture, to be printed, painted, cast, or otherwise placed on or worked into any article of manufacture; or . . . [(4)] shape or configuration of any article of manufacture . . . .[113]

Ultimately, in 1902, Congress arrived at the statute’s current wording by amending the statute to read solely “design for an article of manufacture.”[114]  At the time, the USPTO interpreted the change as a simplification of the language of the statute and not as a limitation of the previous enumeration of patentable subjects.[115]  Although amended twice more in 1939 and 1952, the design patent statute’s wording of the article of manufacture requirement has stayed the same.[116]

2.  Early court interpretations of § 171

While design patents initially protected smaller, tangible items, such as statues and industrial designs,[117] in the early twentieth century, the courts began to interpret the article of manufacture requirement more broadly.  In In re Hadden,[118] the Court of Appeals for the District of Columbia (now known as the D.C. Circuit) faced a novel question on appeal from the USPTO:  whether a designer may claim a patent for a life-sized grandstand.[119]  The USPTO had decided that the grandstand, while a “manufacture” within the meaning of the utility patent statute, was not an “article of manufacture” within the meaning of the design patent statute; it cautioned that an observer would not be aware of the grandstand’s ornamental features because of its size and immobility.[120]  However, the D.C. Circuit dismissed the USPTO’s distinction between a “manufacture” and an “article of manufacture,” finding it nearly impossible to distinguish between the two.[121]  The court ultimately incorporated the accepted meaning of “manufacture” from the utility patent statute into the design patent statute’s article of manufacture requirement.[122]  The court’s holding that size and immobility are not dispositive characteristics thus broadened the term’s accepted meaning.[123]

Shifting away from the tangible, typical design, in In re Hruby[124] the U.S. Court of Customs and Patent Appeals (CCPA) interpreted the scope of an article of manufacture to include the ornamental display of a fountain.[125]  During examination at the USPTO, the designer claimed the following fountain:

Figure 4:  Hruby Design Patent Claim[126]

The examiner, and ultimately the Patent Office Board of Appeals (“the Board”), rejected the claim, finding that because the designer claimed the part of the fountain that was entirely made of water in motion, the design was not within the statutory meaning of an article of manufacture.[127]  The CCPA reversed the Board’s decision, outlining several important factors.[128]  First, the court rejected the notion that something made up of “fleeting” or ephemeral particles should not be protected by a design patent.[129]  To this point, the CCPA analogized the water droplets in a fountain to the atomic particles that constitute all solid objects.[130]  It emphasized that while a solid object appears to be a singular item, it is actually millions of small particles, much like a fountain made up of moving droplets of water that appear to be a continuous, singular stream of water.[131]  Second, the court reaffirmed the holding in Hadden that size and immobility do not create unpatentable subject matter.[132]  Finally, the court rejected the argument that the water sprays did not constitute an article of manufacture because they could not “exist of themselves.”[133]  Specifically, the CCPA held that “the dependence of the existence of a design on something outside itself is [not] a reason for holding it is not a design ‘for an article of manufacture.’”[134]  The court emphasized that many designs depend on outside factors for their outward appearance.[135]  Thus, the CCPA held that under the design patent statute, an “article of manufacture” might be intangible and dependent upon another object.  This was the last time that the CCPA or its successor, the Federal Circuit, heard a case that required a plain text interpretation of § 171’s article of manufacture requirement; however, following the advent of computers, the USPTO had to consider whether software icons were within the scope of the requirement.[136]

3.  Design patent protection and software

Design patents and software had their first encounter at the USPTO as companies began to create and use software icons.[137]  In the 1980s, computer-generated graphics and icons burgeoned onto the design scene.[138]  Around the same time, the Xerox Corporation (“Xerox”) broke new ground at the USPTO by filing design patent applications for its computer icons.[139]  Ultimately, the USPTO issued Xerox design patent protection based on some of its initial applications.[140]  Figure 5 contains a sampling of the protected primitive icons.

Figure 5:  Xerox Software Icon Design Patent Claims[141]

Upon issuing these patents, the USPTO received several letters inquiring whether software icons met the article of manufacture requirement and qualified for design patent protection.[142]  An overwhelming majority of the letters advocated for expanding design patents to protect software icons; however, one letter feared that granting design patents for software icons would blur the line between copyright and patent protections.[143]  After receiving these letters, and presumably after conducting its own study of the subject, the USPTO began rejecting design patent applications for software icons.[144]

The USPTO’s seemingly ad hoc shift on the patentability of software icons resulted in the denial of later Xerox applications.  In Ex parte Strijland,[145] Xerox claimed in its patent application the “design for a[n] Information Icon for Display Screen of a Programmed Computer System.”[146]  Upon initial review, the examiner rejected the software icon as being unpatentable subject matter under § 171.[147]  In response, Xerox argued that the design was “an ornamental design for the display screen of a programmed computer system.”[148]  Further, to pass the § 171 article of manufacture requirement, Xerox identified the computer as the article of manufacture.[149]  The examiner ultimately rejected the application because it did not include a depiction or description of the computer itself in the application.[150]  On appeal from the examiner, the Board upheld the rejection.[151]  The Board explained that merely presenting a picture on a computer’s display does not constitute a protectable design; rather, it is solely because “the icon is an integral part of the operation of a programmed computer” that the potential for patentability exists.[152]

Although the Board’s view in Strijland withstood opposition at the USPTO, subsequent challengers chipped away at its stronghold.  In Ex parte Tayama,[153] the Board appeared open to expanding protection to software icons.[154]  The designer claimed the “ornamental design for an icon for set up operation,”[155] arguing that the icon was “surface ornamentation upon a computer system.”[156]  This line of argument aimed to establish the computer as the article of manufacture required by § 171.[157]  In accord with the logic in Strijland, the Board upheld the rejection because the specification failed to “show or describe” Tayama’s “claimed design embodied in any article of manufacture.”[158]  Again, the Board reiterated that “a picture standing alone is not protectable by a design patent.”[159]  However, similar to Strijland, the Board hinted that if Tayama had included the computer in the application, the icon may have been patentable.[160]

After witnessing the failures of Xerox, attorneys used the CCPA’s holding in Hruby to analogize to the characteristics of Hruby’s fountain to those of a software icon.  In Ex parte Donoghue,[161] the designer injected the logic of the Hruby court—which held that dependency, ephemerality, and permanence do not preclude design patentability—to argue to the Board that the icon design depended upon the computer system that did not need to be disclosed in the application.[162]  The Board rejected this argument, distinguishing the claimed icon as a claim of surface ornamentation and the fountain in Hruby as an applied design.[163]  Because an icon is a form of surface ornamentation, the ornamentation must, to receive a design patent, be applied to an article of manufacture; Donoghue failed to do so in her application.[164]

Following the Board’s decisions in Strijland, Tayama, and Donoghue, the USPTO changed course by expanding design patent protection to software icons and by publishing interim guidelines for examining design patent applications for software icons.[165]  In response to the Board’s concern, the interim guidelines required the designer to include solid lines around the software icon to represent the computer’s display, thereby ensuring compliance with the article of manufacture requirement.[166]  In 1996, the USPTO finalized its regulations, which are now incorporated into the Manual of Patent Examining Procedure (MPEP) and permit the computer display to be illustrated by either solid or dashed lines.[167]  Within the MPEP, the USPTO cites Hruby to justify the broadening of the article of manufacture requirement to include software icons.[168]  According to the MPEP, “[t]he dependence of a computer-generated icon on a central processing unit and computer program for its existence itself is not a reason for holding that the design is not for an article of manufacture.”[169]  At issue in Strijland, Tayama, and Donoghue was whether the claimed icon should be viewed as a claim of surface ornamentation or an actual applied design, like the fountain in Hruby; however, the USPTO dropped this distinction seemingly without any explanation.[170]  Even after the issue of the article of manufacture requirement has been raised in cases before the Board, and ultimately addressed in the MPEP, the Federal Circuit has never heard the question of the scope of design patent eligibility under § 171.[171]

4.  The Federal Circuit’s modern interpretation of the article of manufacture requirement

Although the Federal Circuit has not ruled on the USPTO’s broad interpretation of § 171’s article of manufacture requirement, the court has heard at least two cases interpreting similar “manufacture” requirements in related statutes.  The first case, In re Nuijten,[172] involved the scope of utility patent subject matter under § 101 and was decided in 2007;[173] the second case, ClearCorrect Operating, LLC v. International Trade Commission,[174] involved the jurisdiction of the U.S. International Trade Commission (ITC) under 19 U.S.C. § 1337(a)[175] and was decided in 2015 with its en banc rehearing denied in March 2016.[176]

In Nuijten, the Federal Circuit decided that a “watermarked” signal does not constitute subject matter for a utility patent, consequently falling outside the scope of § 101.[177]  Watermarking is a technique that embeds an electronic signal with additional data.[178]  For example, the watermarking technique is used on digital audio files to prevent unauthorized copying.[179]  The inventor attempted to patent four types of claims relating to the watermarked signals: (1) the process, (2) the device that performs the process, (3) the storage medium that holds the resulting signals, and (4) the signals themselves.[180]  The USPTO granted the first three categories of claims and rejected the fourth claim—the actual watermarked signal.[181]  First, the Board found that the signal had no “physical attributes,” and the claim solely described its abstract characteristics.[182]  Second, the signal did not fall into any of the four categories of patentable subject matter outlined in § 101—“process, machine, manufacture, or composition of matter.”[183]  Third, the Board found that the signal was not a tangible object and thus failed to meet the definition of “manufacture.”[184]

In its analysis, the court dealt with the first ground of the Board’s rejection, ruling that the claim should be construed as claiming the signal itself.[185]  The court found that the signal had physical attributes and thus was not a claim for solely the abstract characteristics of the signal.[186]  Next, the court turned to an analysis of whether the signal fit into the statutory subject matter of § 101.[187]  After rejecting the signal as either a process or a machine, the court turned its attention to the category of a manufacture.[188]  Upon facing this difficult question, the court examined the Supreme Court’s landmark case interpreting the breadth of § 101, Diamond v. Chakrabarty,[189] for guidance on the meaning of “manufacture.”[190]  In Chakrabarty, the Court interpreted the term “manufacture” (in its verb form) very broadly, citing legislative history and Congress’s use of broad language as evidence that Congress recognized that some “inventions are often unforeseeable.”[191]  In Nuijten, however, the Federal Circuit construed “manufacture” as a noun rather than a verb and defined the term using the same dictionary the Supreme Court used in Chakrabarty.[192]  Ultimately, the court equated “manufacture,” used in noun form, to an “article of manufacture,” and found that the term referred to “tangible articles or commodities.”[193]  Subsequently, while finding the signal physical, the court held that, as defined by the claim, the signals did not comprise a tangible article.[194]  Thus, the court found that the claimed signals did not meet the meaning of “manufacture” in § 101.[195]

In his concurrence and dissent, Judge Linn raised the issue of a potential contradiction of the majority’s interpretation of “manufacture” in Nuijten with the CCPA’s previous interpretation of “article of manufacture” in Hruby.[196]  Attempting to elucidate the potential contradiction, the majority distinguished Nuijten from Hruby in a footnote, emphasizing that this interpretation of “article of manufacture” was limited to a utility patent under § 101 and that this case did not affect the “article of manufacture” for the patentability of designs under § 171.[197]

The Federal Circuit returned to the term “article” in ClearCorrect, interpreting the phrase within 19 U.S.C. § 1337(a) to determine whether the ITC had jurisdiction.[198]  This case dealt with importing three-dimensional digital models of orthodontic aligners.[199]  Align Technology, Inc. (“Align”) alleged that ClearCorrect Operating (“ClearCorrect”) violated 19 U.S.C. § 1337 (“section 337”) on a theory of patent infringement.[200]  The orthodontic aligners at issue were designed to incrementally reposition a patient’s teeth.[201]  ClearCorrect scanned patients’ teeth in the United States and sent the three-dimensional models to its Pakistan office, which then created the incremental positioning scheme for the teeth.[202]  After the positioning scheme was complete, the Pakistan office sent the three-dimensional models back to the United States, where employees subsequently printed the models to use to mold the orthodontic aligners.[203]  As set by section 337, the ITC’s jurisdiction is limited to “unfair acts” involving the “importation of articles.”[204]  Thus, to establish jurisdiction, the ITC had to determine that the three-dimensional digital models constituted an “article” within the meaning of section 337.  Accordingly, the ITC determined that the use of “articles” within section 337 included digital data.[205]

The Federal Circuit reversed the ITC and held that the meaning of “articles” only extends to “material things” and thus does not extend to three-dimensional digital models.[206]  To determine the meaning of “articles,” the court walked through four phases of statutory analysis:  first, construing the term in its ordinary meaning; second, turning to the term’s use throughout section 337; third, looking at the full statutory scheme; and fourth, examining the statute’s legislative history.[207]  In the first phase of analysis, the court surveyed numerous dictionaries contemporaneous to the passage of section 337’s predecessor in which Congress initially used the phrase “articles.”[208]  Upon review of the dictionaries, the court maintained that “articles” meant solely material things, and the term did not extend to intangible articles.[209]  Consequently, the court concluded that an “article” did not include electronically transmitted three-dimensional digital models.[210]  In the second phase, the court found that the structure of section 337 reinforced the conclusion that Congress intended for “articles” to mean material things.[211]  Here, the court focused on the exclusionary purpose of section 337.[212]  Because the purpose of the act is to prevent items that infringe intellectual property from entering the United States, the fact that it was impracticable to stop electronic transmission would make the statute unenforceable.[213]  As a result of this analysis, the court rejected Align’s invitation to read section 337 broadly enough to encompass electronic signals.[214]

The third and fourth phases of analysis continued along the same lines as the initial two.  In the third phase of its statutory analysis, the court found no help in the statutory scheme to include a digital model within the meaning of an article.[215]  Whether considering exclusion orders, cease and desist orders, or tariff schedules, the court concluded that each was directed at the regulation of material things and not the transmission of digital data.[216]  Finally, the court examined the legislative history of section 337.[217]  In its decision below, the ITC posited that, because Congress used a variety of words to describe “articles,” the legislative history indicated that the word should be read more broadly than “material things.”[218]  However, the court emphasized that Congress “unambiguously” intended that the meaning of “articles” only extend to “material things.”[219]  The court ultimately concluded that Congress, rather than the ITC, was in a better position to determine what should be included in the statute as an “article.”[220]

In a vehement dissent, Judge Newman argued that the majority’s holding was contrary to the purpose of section 337 and conflicted with binding precedent and other judicial bodies.[221]  She submitted that the Information Age changed the technology world and that, to serve its statutory purpose, section 337 needed to evolve to facilitate remedies against modern unfair competition.[222]  Judge Newman emphasized that section 337 was meant to apply “to all patented technologies, including digital technologies, whatever the path of importation.”[223]  Further, she rejected the tangible limitation on “articles” within the meaning of section 337,[224] contending that Congress could not have intended to omit future technologies it could not foresee when it enacted the statute as well as the majority’s read-in limitation.[225]

Following their defeat, Align and the ITC each filed petitions for an en banc rehearing; both petitions were denied.[226]  However, the panel’s split, and its fervor, persisted in the denial of the en banc petition for a rehearing.[227]

II.  Virtual and Augmented Reality: The Federal Circuit’s Crash Course with the Technologies and the Need for a Broad Interpretation of § 171

The maturity and rapid growth of the VR and AR markets are blurring the lines between the physical and digital words, and more designers in these markets will seek design patent protection.  Therefore, whether a three-dimensional digital model constitutes an “article of manufacture” within the meaning of § 171 is likely to become a much-debated topic.  Congress’s simplification of the statutory text of § 171 and the CCPA’s and USPTO’s most recent direct interpretations of § 171’s article of manufacture requirement support a broad interpretation of the phrase “an article of manufacture” that includes three-dimensional digital models.[228]  Based on this interpretation, the USPTO should grant design patents to three-dimensional digital models.[229]  In two recent cases, however, the Federal Circuit has signaled a narrowing of the scope of the “article of manufacture” language and has explicitly excluded electronic and digital technologies.[230]  While the court arguably respects the plain language meaning of these terms at the time Congress enacted these statutes, its refusal to expand the scope of the article of manufacture requirement does so at the expense of congressional intent evidenced by the design patent statute’s legislative history.

A.  The Federal Circuit Has Signaled a Limitation on Statutory Subject Matter by Adopting a Narrow Meaning of an “Article of Manufacture” in a Statute Related to the Design Patent Statute

In its two most recent decisions interpreting the phrase “article of manufacture,” the Federal Circuit has signaled a much narrower view than that held by its predecessor court—the CCPA—and the USPTO.[231]  In Nuijten, the court indicated that it holds a narrow view of the definition of an article of manufacture.[232]  In ClearCorrect, the Federal Circuit confirmed this view, holding the same limited view of an article of manufacture as in Nuijten.[233]  Further, ClearCorrect continues to evince the court’s willingness to limit the definition of an article of manufacture to the physical world.[234]

1.  The narrow definition of “manufacture” in In re Nuijten

The Federal Circuit departed from a broad reading of the article of manufacture requirement in Nuijten.[235]  In Nuijten, the court narrowed the definition of a “manufacture” in its interpretation of § 101, the same statutory provision that the Supreme Court interpreted in Chakrabarty.[236]  Because it interpreted “manufacture” in § 101 to be a noun, the court denied patent protection for a watermarked electrical signal because the signal was “fleeting”; “devoid of any semblance of permanence”; and dependent on a machine to be “perceived.”[237]  Given the close relationship between § 101 and § 171 and the Federal Circuit’s willingness to import meanings derived from the utility patent statute into the design patent statute, the court could import the narrowed meaning of manufacture into its interpretation of § 171.[238]

The characteristics of Nuijten’s electronic signal that the court identified as precluding utility patentability are similar to the characteristics of the Hruby fountain, which the CCPA upheld as patentable.  Specifically, the Federal Circuit described Nuijten’s electronic signal as “fleeting,” “devoid of any semblance of permanence,” and dependent on a machine to be “perceived,”[239] while the CCPA described the particles that made up Hruby’s fountain as “fleeting,” and found that the fountain itself lacked “permanence” and was “dependen[t]” on the flow of water.[240]  Despite these similar characteristics, however, the two courts did not come to the same conclusions.  While the CCPA in Hruby held that tangibility, dependence, and permanence did not preclude a design from patentability, the Federal Circuit in Nuijten held that these characteristics did preclude patentability.[241]

Judge Linn, in his concurrence and dissent in Nuijten, pointed out the inconsistency of the Federal Circuit’s decision to interpret the word “manufacture” in the utility patent context differently than it had in the design patent context in Hruby.[242]  He stated that, “In In re Hruby, we held that it was not the dynamic position of any given water droplet, but rather the overall pattern, that was patentable; likewise, here, it is the overall signal, not the physical manifestation of a single bit, that constitutes the invention.”[243]  To counter Judge Linn’s point, the majority argued that because requirements for patentability differed in the utility and design realms, there would not be a contradiction issue.[244]  Nevertheless, the court appears to ignore the fact that the requirements for patentability—novelty, obviousness, and subject matter—are independent from each other.[245]  Consequently, because the design and utility patent statutes have an independent subject matter requirement that includes the word “manufacture,” it is immaterial to point out that there are other, dissimilar requirements.[246]  The court’s jurisprudence, which imports utility patent concepts and interpretations into the design patent statute, further underscores the argument that the limited meaning of “manufacture” could likely be imported into the interpretation of § 171.[247]

Because of § 171’s language subjecting it to other “conditions and requirements” of Title 35, the Federal Circuit has freely imported the statutory interpretation of utility patent requirements into the requirements for design patentability.[248]  Thus, given the similarity of the wording between the subject matter requirements for design and utility patents, the design patent statute’s grant permitting the importation of utility patent requirements, and the court’s history of actually importing these requirements, it is extremely likely that, given the invitation, the Federal Circuit would import Nuijten’s manufacture requirement into the design patent statute.  This importation would necessarily overturn Hruby.[249]

There are many similarities between the watermarked signal in Nuijten and a three-dimensional digital model used in VR and AR technologies.  Both three-dimensional digital models and watermarked signals are purely electronic, exist temporarily, and depend on some other device to exist.[250]  Thus, assuming the court would not distinguish an electronic signal and a three-dimensional digital model, a three-dimensional model would fail to be patentable if the court imported the interpretation of a manufacture from Nuijten into the meaning of design patent’s § 171.

2.  The Federal Circuit’s adherence to the limited definition of “manufacture” in ClearCorrect Operating, LLC v. International Trade Commission

In ClearCorrect, its most recent opinion interpreting the phrase “article of manufacture,” the Federal Circuit maintained its narrow view from Nuijten.[251]  The dental models in ClearCorrect are the closest analogous subject matter to the types of digital models that are found in the VR and AR worlds.[252]  Through its analysis, the court undertook a lengthy, four-part statutory interpretation, ultimately resulting in a narrow definition of the word “articles” that excluded three-dimensional digital models.[253]  However, the court was not unanimous:  Judge Newman wrote a vigorous dissent in that case and also dissented to the denial of a rehearing en banc.[254]  Still, the majority’s limited definition of an article of manufacture was consistent with the narrow view outlined in Nuijten, ultimately showing that the court would continue to adhere to the interpretation excluding digital media.[255]

The court in ClearCorrect interpreted the Section 337 use of “articles” as limited to tangible, material things; however, the analysis strictly adhered to the understanding of technology and products of the early twentieth century.  The court unnecessarily restricted itself to a century-old understanding of the meaning of “articles” as outlined in dictionaries and tariff schedules.[256]  As a result, the court ignored Congress’s intent in passing the statute, which was to provide an additional safeguard against unfair competition by imports; instead, the court focused on the practicability of enforcing a ban on importation of intangible, digital media.[257]  With the emphasis on tangibility, it is unsurprising that dictionaries from the early twentieth century supported the court’s narrow view; the advancement of electronic and digital technologies, which expanded society’s awareness of intangible commerce, was obviously unforeseen at that time.[258]  Underscoring this point, as Judge Newman emphasized in her dissent, the Supreme Court has held that when interpreting statutes that were passed before the Information Age, the courts “must read the statutory language . . . in the light of drastic technological change.”[259]  When read in this light, courts should apply a broader view of the term “articles,” which would include three-dimensional digital models.

Further, as Judge Newman pointed out in her dissent to the decision denying the rehearing en banc, the Federal Circuit’s stance on an article of manufacture counters the reading of the term in patent law.[260]  In passing Section 337, Congress aimed to protect domestic industry by safeguarding against unfair competition from imports that infringe upon U.S. intellectual property rights, including patents.[261]  Thus, when interpreting the term “article” in Section 337, the Federal Circuit should have maintained a reading consistent with the interpretation of the term in the utility patent statute.  Based on the limited definition of manufacture that the Federal Circuit adopted in Nuijten, which rejected a watermarked electronic signal as patentable subject matter, the court did just that:  it continued to read the term in a more limited light.[262]  However, as discussed earlier, in Chakrabarty, the Supreme Court established its broad, inclusive view of utility patentable subject matter.[263]  The Court explained that “Congress is free to amend” the patent statute, insofar as to limit any subsequent interpretation by the courts.[264]  Contrary to the Supreme Court’s reading, the Federal Circuit in ClearCorrect, acknowledging that the last revision of Section 337 occurred prior to the creation of the Internet, stated the opposite of the Supreme Court:  “Congress is in a far better position to draw the lines” of what should be included in the meaning of articles within Section 337.[265]  Therefore, even though it did not interpret the patent statute directly, the Federal Circuit still severely limited a remedial option available to patentees.

ClearCorrect, which involved a three-dimensional digital model, is the case most analogous to a design patent dispute involving a model found in VR or AR.  While it is possible to argue that the ClearCorrect court’s decision is only applicable to the meaning of an article within the ITC’s jurisdictional statute, this seems increasingly doubtful because of the court’s view of an electronic signal in Nuijten.[266]  Thus, based on ClearCorrect and Nuijten, it is unlikely that upon hearing a case directly interpreting the term “article of manufacture” within § 171, the Federal Circuit would expand this position.  In fact, it is more likely that the court imports Nuijten’s interpretation of § 101 into § 171, overruling CCPA’s Hruby decision and ending the USPTO’s practice of granting design patents for software icons.

B.  The Changes in the Design Patent Statute Allude to a Broad Interpretation

Based on the text of § 171, its legislative history, as well as how the courts have incorporated the interpretations of the utility patent statute into design patent law, the Federal Circuit should adopt a broad view of the article of manufacture requirement.  A textual analysis of § 171 supports a broad interpretation of the article of manufacture requirement.  The statute currently requires that a design merely be “for an article of manufacture.”[267]  This broad language demonstrates the statute’s comprehensive scope.[268]

Further, the consistent simplification of the statutory language reflects Congress’s preference for an inclusive patent subject matter policy.[269]  Over a period of sixty years, Congress repeatedly simplified the language of § 171 from narrow, enumerated categories to broad, general language including “any” and “manufacture.”[270]  This legislative history further indicates that Congress rejected a narrow interpretation of the article of manufacture requirement.

Finally, the broad interpretation of the analogous utility patent provision § 101 also supports a broad interpretation of the design patent provision § 171.  In Chakrabarty, for instance, the Supreme Court construed § 101 and emphasized that, by choosing words like “any” and “manufacture,” Congress intended for courts to read § 101 broadly.[271]  It also found ample support in § 101’s legislative history supporting this view.[272]  The incorporation of these utility patent provisions into § 171 therefore stems from § 171’s wording and legislative history because § 171 is “subject to the conditions and requirements of [Title 35].”[273]  Moreover, Congress’s preference for an inclusive subject matter policy in § 171 is in accord with the Court’s interpretation of § 101.[274]  The language of § 171 and § 101 uses similarly expansive terms such as “any” and “manufacture.”[275]  Thus, like the language and legislative history of § 101, the language and legislative history of § 171 allude to an inclusive, broad reading.[276]  Further, the courts have previously looked to the utility patent statute to justify broadly construing other terms in § 171.  This practice of incorporating § 101 to set the boundaries of § 171 should therefore make the Federal Circuit feel comfortable continuing that trend and establishing a broad interpretation of § 171’s article of manufacture requirement.

Thus, because of the choice of language in the statute, the legislative history of § 171, and the tradition of incorporating analogous provisions of the utility patent statute, the Federal Circuit should read the statutory language “article of manufacture” broadly.

C.  Applying the Broad Interpretation of § 171

1.  The Hruby view of an article of manufacture includes three-dimensional digital models

When the CCPA adopted a broad interpretation of § 171 in Hruby, it provided a helpful framework to analyze three-dimensional digital models.  Specifically, the Hruby court considered the design’s permanence, tangibility, and dependence.[277]

Patentability hinges on the ordinary observer’s perception of the three-dimensional model, not whether the virtual design itself is tangible.[278]  Just as the fountain in Hruby ends when the water flow stops, a three-dimensional model in the virtual world ceases to exist when the computer acting as the engine of the virtual world is shut down.  However, the ephemerality of the design should not limit its ability to be protected.[279]  “Presence” within the VR and AR worlds allows for the creation of an environment that an observer’s mind considers reality.[280]  Accordingly, while the VR or AR technology is in use, an observer views a three-dimensional model as if it constantly appeared, much like the fountain in Hruby had a “constant” appearance.[281]  Hence, a three-dimensional model should not be precluded from design patent protection just because it only exists while in use.  Further, a three-dimensional model’s dependence on a computer engine should not exclude the model from being considered an article of manufacture.  Just like the fountain in Hruby depended on water flow to operate, a three-dimensional model depends on the computer that generates it.  Moreover, the CCPA in Hruby explicitly held that dependency does not preclude a design from being considered an article of manufacture under § 171.[282]  Accordingly, the fact that a three-dimensional digital model is dependent on the computer should not preclude it from being considered an article of manufacture and receiving design patent protection.

Including three-dimensional models in the scope of § 171 does not alter the test for design patent infringement.  Design patent infringement is judged from the perspective of an “ordinary observer.”[283]  The test evaluates whether a purchaser would find substantial similarities between a protected design and the alleged infringing design.[284]  Therefore, if an ordinary observer would view the three-dimensional digital model and confuse it with a protected design, then it is possible to find infringement even though the infringing object is a digital model rather than a physical object.[285]

Furthermore, the size and mobility of a design do not affect whether the design constitutes an article of manufacture within the meaning of § 171.[286]  The Hruby court and, prior, the Hadden court, underscored what constitutes an article of manufacture and clarified that size and mobility should not restrict this definition.[287]  Thus, a three-dimensional digital model should not be blocked from design patent protection simply because it does not have a physical size and is not physically mobile.

2.  The USPTO has adopted the Hruby court’s view and should issue patents for three-dimensional digital models that are present in VR and AR

The USPTO expanded the meaning of an article of manufacture to include software icons, adopting the Hruby court’s broad view of patentability.[288]  As technology has progressed, the software industry has shifted away from programming three-dimensional models for display on the computer screen towards creating environments in the VR and AR worlds.[289]  Thus, because the USPTO has already shown that it wants to protect new technologies by adopting the Hruby court’s view, it should follow this next progression of technology and explicitly permit design patents to issue for three-dimensional digital models.

It is irrelevant that the three-dimensional model does not appear directly on the computer screen like the permitted software icon.  As the Board at the USPTO decided in Strijland, Tayama, and Donoghue, a software icon would be supported only if it was an ornamentality “for an article of manufacture.”[290]  Thus, the USPTO eventually granted design patent protection for software icons if the claim included an outline around the icon representative of the computer screen.[291]  The USPTO’s view of the computer icon as being an ornamentality “for an article of manufacture” should not apply to three-dimensional models.  Because the VR and AR technologies’ achievement of “presence” has blurred the lines between the digital and the physical worlds, it is no longer necessary to distinguish when an object appears on a computer screen by using solid or dashed lines around the claimed digital design.[292]

The USPTO should grant design patent protection without requiring use of a solid or dashed line around the claim because, while a three-dimensional model is a digital design, it is different from a software icon.  The key difference between the two is that a software icon itself exists on a computer screen or as part of a software program, making it unclear how the icon is displayed without providing the context of the computer screen.[293]  Unlike a software icon, a three-dimensional model does not need context for the user to understand how the model is displayed because the model is presented as part of physical reality, not a computer screen.  Therefore, the USPTO should continue to use the broad view of the Hruby court and grant protection to three-dimensional digital models.


The Federal Circuit should abandon the recently adopted line of reasoning interpreting an article of manufacture as a physical, tangible object in the utility patent and ITC jurisdictional statutes.  In its most recent interpretation of § 171, the Federal Circuit’s predecessor court, the CCPA, broadened the definition of an article of manufacture to include a fountain, an object that is dependent on a machine to run, ephemeral, and transient.[294]  This expansion is in accord with the simplification of § 171, which moved from enumerated categories of subject matter to a much broader wording.[295]  Just as the USPTO expanded design patent subject matter to include software icons, the court should interpret articles of manufacture to include three-dimensional digital models.  The inclusion of digital models will allow designers who are developing items for use in VR and AR worlds, as well as those designers whose items already exist in the physical world, to fully protect their intellectual property rights thus ensuring that statutory structure keeps pace with the boom in VR and AR technologies.  Without abandoning its current course, the Federal Circuit’s narrow interpretation puts design patent protection of these new technologies at risk.

A simplified explanation of the USPTO appeals process is as follows:  Upon an adverse decision on patentability from an examiner, the appellee must file a notice of appeal and submit an appeal brief to the Board.  Appeals, U.S. Pat. & Trademark Off. (Jan. 25, 2016), https://www.uspto.gov/patents-application-process/patent-trial-and-appeal-board/appeals.  The examiner who reviewed the initial application then files an answer to the Board.  Id.  Upon review of the briefs, and after an oral hearing, if granted, the Board issues its decision.  Id.  For a more detailed overview of the ex parte appeals process at the USPTO, see William F. Smith, An Overview of Ex Parte Patent Appeals in the USPTO, Am. Intell. Prop. L. Ass’n (June 15, 2016), https://www.aipla.org/learningcenter/PTABBenchAndBar2016/PTAB%202016%20Bench%20%20Bar%20Conference/Walters_Paper.pdf.

    [154].    Specifically, the Board indicated that software icons might fall within the scope of the article of manufacture requirement:

We have no doubt that the claimed design, like all surface ornamentation-type designs, could be used to ornament a wide variety of articles, including computers.  However, the phrase “design for an article of manufacture” in
§ 171 requires more than a depiction of the surface ornamentation alone.  It requires disclosure of the ornamentation applied to or embodied in an article of manufacture.  More than an applicant’s generalized intent to ornament some article is required.  It is the application of the design to an article which separates mere pictures from a design protectable by a patent.  Without disclosure of an article, the design is not an applied design contemplated for protection under § 171.

    [163].    Id.  The Board explained the difference between an abstract design and an applied design:

While the design must be embodied in some article, the statute is not limited to designs for complete articles, or ‘discrete’ articles, and certainly not to articles separately sold. . . .  Here the design is embodied in the shank portion of a drill and a drill is unquestionably an article of manufacture.  It is thus applied design as distinguished from abstract design.
