PTO Creates Separate Design Patent Bar

by Amol Parikh | Dec 7, 2023 | Patents

The US Patent & Trademark Office (PTO) published its final rule, creating a separate design patent bar where admitted design patent practitioners will practice in design patent proceedings only. (88 Fed. Reg. 78644 (Nov. 16, 2023).)

Prior to this rulemaking, there was a single patent bar for those who practice in patent matters before the PTO, including in utility, plant and design patent proceedings. PTO regulations previously required that all patent bar practitioners pass a registration exam and possess specific and stringent scientific and technical qualifications, such as an engineering degree or substantial course work in physics, biology, chemistry or the like.

The new rule creates a separate design patent bar that still requires members to pass the current registration exam but permits applicants to have a bachelor’s degree, master’s degree or PhD in any of the following areas from an accredited college or university:

Industrial design
Product design
Architecture
Applied arts
Graphic design
Fine/studio arts
Art teacher education.

The new rules expanding the patent bar admission criteria are intended to encourage broader participation and to keep up with the ever-evolving technology and related teachings that qualify someone to practice before the PTO. Practitioners currently admitted before the PTO will not be impacted by the change and can continue to prosecute utility, plant and design patents.

The rule will take effect on January 2, 2024.

PTO Provides Guidance for Computer-Related Design Patent Applications

by Peter Brunovskis, PhD | Nov 30, 2023 | Patents

The US Patent & Trademark Office (PTO) published a notice regarding supplemental guidance for PTO personnel examining design patent claims containing computer-generated images. 88 Fed. Reg. 80277 (Nov. 17, 2023).

The guidance clarifies how to satisfy the article of manufacture requirement under 35 U.S.C. 171 for ornamental designs relating to computer-generated icons shown on a display panel, as discussed in Section 1505.01(a)(I) of the Manual of Patent Examining Procedure (MPEP). According to the guidance, “the mere display of a computer-generated electronic image . . . on a display panel does not constitute statutory subject matter under 35 U.S.C. 171.” However, a computer icon or a graphical user interface (GUI) shown on a display panel (e.g., a computer screen, monitor, computer display system, mobile phone screen or virtual/augmented reality goggles) is more than a mere display of a picture on a screen because it constitutes an integral and active component in the operation that is embodied in and/or applied to a programmed computer displaying the computer icon or the GUI. Thus, if a computer icon or GUI is properly presented and claimed (e.g., the drawing fully discloses the design as embodied in the article of manufacture), it is eligible under 35 U.S.C. 171.

In addressing the foregoing distinctions, the guidance sets forth specific standards for PTO personnel, including consideration of the complete disclosure when evaluating whether a design claim containing a computer-generated electronic image complies with the article of manufacture requirement. For example, given that computer icons or GUIs are considered to be two-dimensional images, which standing alone are surface ornamentation (i.e., an ornament, impression, print or picture), the guidance stipulates that the title and the claim should not be for a computer icon or a GUI alone, but rather an article of manufacture, such as a “display panel with a computer icon.” The guidance further provides examples of acceptable claim language and specific examination scenarios for evaluation.

Chilly Adventures: Design Patent Prior Art Comparison Applies to Article of Manufacture

by Amol Parikh | Sep 28, 2023 | Patents

Addressing a matter of first impression concerning the scope of prior art relevant to a design patent infringement analysis, the US Court of Appeals for the Federal Circuit concluded that “to qualify as comparison prior art, the prior-art design must be applied to the article of manufacture identified in the claim.” Columbia Sportswear North America, Inc. v. Seirus Innovative Accessories, Inc., Case Nos. 21-2299; -2338 (Fed. Cir. Sept. 15, 2023) (Prost, Reyna, Hughes, JJ.)

Columbia owns a design patent that covers an ornamental design of a heat reflective material. Seirus markets and sells products (e.g., gloves) made with material that it calls HeatWave. An image of Columbia’s patented design and Seirus’s HeatWave material appear below:

Columbia Patented Design

Seirus HeatWave

Columbia sued Seirus for infringement. After the district court granted summary judgment of infringement, Seirus appealed to the Federal Circuit. The Court issued its decision in Columbia I, concluding that the district court improperly declined to consider the effect of Seirus’s logo in its infringement analysis and resolved certain issues that should have been left to the jury. The Court therefore vacated summary judgment and remanded for further proceedings.

On remand, the district court held a trial. Before trial, the district court limited admissible comparison prior art to “wave patterns of fabric,” declined to instruct the jury that “prior art” referred to prior designs of the claimed article of manufacture, and declined to instruct the jury that it did not need to find that any purchasers were deceived or that there was any actual or likelihood of confusion among consumers in the marketplace. Seirus was permitted to admit three prior art references that disclosed fabric, and Columbia was precluded from distinguishing the references by arguing that they did not disclose heat reflective material. The jury returned a verdict of noninfringement. Columbia appealed.

Among other things, Columbia challenged the exclusion of evidence and jury instructions concerning comparison prior art, and the jury instructions implicating Seirus’s logo.

The Federal Circuit began by discussing the appropriate prior art comparison in the context of design patent infringement. Citing its 2008 en banc decision in Egyptian Goddess v. Swisa, the Court explained that under the ordinary-observer test governing design patent infringement, prior art can help highlight distinctions and similarities between the claims and the accused design. For instance, when a claimed design is close to a prior art design, small differences between the accused design and the claim design are likely to be important. Conversely, if an accused design copied a particular feature of the claimed design that departs from the prior art, the accused design is likely to be regarded as deceptively similar to the claimed design, and thus infringing.

The question of first impression before the Federal Circuit was the proper scope of comparison prior art that may be [...]

Federal Circuit to Revisit Whether KSR Extends to Design Patents

by Courtney Seams | Jul 13, 2023 | Patents

Granting a petition for rehearing en banc, the US Court of Appeals for the Federal Circuit decided to revisit the effect of the Supreme Court’s 2007 decision in KSR International v. Teleflex on design patents. LKQ Corporation v. GM Global Technology Operations, Case No. 21-2348 (Fed. Cir. June 30, 2023) (per curiam). The Federal Circuit withdrew its earlier panel decision addressing KSR’s application to design patents.

This case arose from an inter partes review (IPR) filed by LKQ against GM alleging that GM’s design patent for a vehicle fender was obvious and/or anticipated. In its original opinion, the Federal Circuit applied its predecessor court’s design patent test for obviousness in In re Rosen (CCPA 1982), as well as its decision in Durling v. Spectrum Furniture (Fed. Cir. 1996), ultimately finding that GM’s design patent was not obvious or anticipated and affirming the Patent Trial & Appeal Board’s decision. The Federal Circuit determined that it was unclear whether the Supreme Court had overruled Durling and Rosen with KSR, so it did not apply KSR. Judge Lourie provided an additional opinion that KSR did not overrule Rosen. Judge Stark concurred in the judgment but found that LKQ had forfeited its argument that KSR overruled Rosen.

In its order for en banc review, the Federal Circuit asked the parties to address whether KSR abrogates Rosen and Durling and whether KSR applies to design patents regardless of whether it overrules or abrogates Rosen and Durling. Specifically, the Court inquired whether KSR’s “expansive and flexible approach” means that Durling’s two requirements should be modified or eliminated. Durling’s first requirement is that “[b]efore one can begin to combine prior art designs . . . one must find a single reference, ‘a something in existence, the design characteristics of which are basically the same as the claimed design.’” Its second requirement is that secondary references “may only be used to modify the primary reference if they are ‘so related to the primary reference that the appearance of certain ornamental features in one would suggest the application of those features to the other.’”

The Federal Circuit also asked the parties to address the appropriate test for evaluating the obviousness of design patents in the event the Rosen-Durling test was to be eliminated or modified.

The Federal Circuit further requested that the parties address whether eliminating the Rosen-Durling test would cause uncertainty in a settled area of law. Finally, the Court asked whether any differences between design patents and utility patents are relevant to the design patent obviousness inquiry.

The Federal Circuit indicated that the issues of anticipation and forfeiture from the initial appeal were preserved, but that additional briefing on those issues was not required. The Court invited the United States to participate as amicus curiae.

Practice Note: With the Federal Circuit granting rehearing en banc, there is a possibility that the Court may extend the obviousness analysis of KSR to design patents.

KSR Does Not Extend to Design Patents (Yet)

by Courtney Seams | Feb 9, 2023 | Patents

Addressing the standard for obviousness of design patents, the US Court of Appeals for the Federal Circuit, in a per curiam opinion, upheld the Patent Trial & Appeal Board’s finding that a challenged design patent was not obvious over the pre-KSR design patent obviousness test or anticipated. LKQ Corporation v. GM Global Technology Operations, Case No. 21-2348 (Fed. Cir. Jan. 20, 2023) (per curiam) (Lourie, J., concurring) (Stark, J., concurring).

GM owns a design patent for the fender of a vehicle. LKQ Corp. previously held a license to the patent from GM, but negotiations to renew the license failed. Because LKQ continued to manufacture the fender after the expiration of the license, GM sent LKQ notice that it was infringing the patent. In response, LKQ petitioned for an inter partes review against GM, alleging that the patent was obvious and/or anticipated.

The Board found that LKQ had not presented enough evidence to prove that the patent was obvious or anticipated. For purposes of evaluating the obviousness of the design over prior art, the Board defined ordinary observers as “retail consumers who purchase replacement fenders and commercial replacement part buyers.” The Board concluded that, from the perspective of the ordinary observer, there were multiple differences between the patented design and the key reference, a prior art design patent. LKQ appealed.

LKQ argued that the Board erred in finding that there was no anticipation and in applying the obviousness tests of In re Rosen (C.C.P.A. 1982) and Durling v. Spectrum Furniture (Fed. Cir. 1996) because the Supreme Court of the United States overruled those tests in KSR International v. Telflex (2007).

The Federal Circuit upheld the Board’s definition of the ordinary observer. The Court found that retail purchasers of the entire vehicle would not be included in the ordinary observer group because purchasers of the product embodying the design are interested in the part itself, not the vehicle as a whole. The Court went on to uphold the Board’s application of the ordinary observer obviousness test, agreeing that the patented design created different overall impressions from the prior art for purposes of both obviousness and anticipation.

The Federal Circuit then addressed whether KSR overruled the Durling and Rosen tests for obviousness of design patents. The Court found that LKQ properly preserved the argument for appeal by asserting it in its opening brief to the Board. The Court then found that it was unclear whether the Supreme Court overruled Durling and Rosen, and therefore the Court was bound to apply the existing law. In applying the Durling and Rosen tests, the Court found that LKQ had failed to identify “the correct visual impression created by the patented design as a whole” because the prior art patent lacked certain key design features of the patented design. Thus, the Court affirmed the Board’s finding that the patent was not obvious.

Judge Lourie provided an additional opinion and addressed LKQ’s argument that KSR overruled Rosen. Lourie stated that because KSR did not involve design patents, which [...]

Design Patent Prior Art Must Be From Same or Analogous Field as Claimed Article of Manufacture

by Paul Devinsky | Oct 14, 2021 | Patents

Finding that the Patent Trial & Appeal Board (Board) applied an erroneous interpretation of claim scope, the US Court of Appeals for the Federal Circuit reversed a Board decision upholding an examiner’s rejection of a lip implant design patent as anticipated by a non-analogous art tool. In re: SurgiSil, Case No. 20-1940 (Fed. Cir. Oct. 4, 2021) (Moore, C.J.)

SurgiSil filed a design application for a lip implant shaped like a generally cylindrical rod that tapered to a point at each end. The examiner rejected the patent as anticipated by a “stump,” an art tool of similar, almost identical, shape used for smoothing and blending areas of pastel or charcoal. SurgiSil appealed the rejection to the Board. The Board affirmed the rejection, finding that the differences in the shapes of SurgiSil’s lip implant and the art tool were minor. The Board rejected SurgiSil’s argument that the two articles of manufacture were “very different,” reasoning that it is irrelevant whether a prior art reference is analogous for anticipation purposes. SurgiSil appealed.

Reviewing the Board’s legal conclusions de novo, the Federal Circuit found that the Board erred as a matter of law. Citing 35 U.S.C. § 171(a) and the 1871 Supreme Court decision in Gorham Co. v. White, the Court explained that a design patent claim does not cover the design in the abstract, and that it is limited to the particular article of manufacture identified in the claim. The Court concluded that the claimed design was limited to a lip implant, did not cover other articles of manufacture and that the Board’s decision therefore rested on an erroneous interpretation of the claim’s scope.

Objective Indicia of Nonobviousness for Design Patents: Same Nexus Requirement as Utility Patents

by Paul Devinsky | Aug 26, 2021 | Patents

The US Court of Appeals for the Federal Circuit reversed two decisions by the Patent Trial & Appeal Board (Board), finding that a soup company and soup dispenser manufacturing company failed to prove the unpatentability of two design patents covering can dispensers. The Court also concluded that the analysis for objective indicia of nonobviousness for utility patents also applies to design patents. Campbell Soup Co. v. Gamon Plus, Inc., Case Nos. 20-2344, 21-1019 (Fed. Cir. Aug. 19, 2021) (Moore, J.)

Gamon Plus owns two design patents directed to “the ornamental design for a gravity feed dispenser display,” or a can dispenser. Gamon’s commercialized embodiment is called the iQ Maximizer gravity feed dispenser. For nearly a decade, Gamon sold tens of millions of dollars’ worth of its iQ Maximizer to Campbell Soup. Campbell attributed increased soup sales in part to the iQ Maximizer in its 10-K Securities and Exchange Commission reports (an industry publication) and in an internal marketing study. Campbell later began purchasing similar gravity feed dispensers from Trinity Manufacturing.

Gamon sued Campbell and Trinity for design patent infringement. Campbell and Trinity then petitioned for inter partes review (IPR) of Gamon’s patents. In its final written decisions, the Board found that Campbell and Trinity failed to prove unpatentability because the prior art was not similar enough to the claimed designs to constitute a proper primary reference. Trinity (Campbell) appealed.

In that appeal, the Federal Circuit disagreed, vacated and remanded. On remand, the Board again held that Campbell and Trinity failed to prove unpatentability, finding that the claimed designs would not have been obvious over the prior art. The Board reasoned that although the prior art alone had the same overall visual appearance as the claimed designs, there existed objective indicia of nonobviousness, including Gamon’s commercial success in selling iQ Maximizers to Campbell, Campbell’s praise of—and commercial success in—using the iQ Maximizer and Trinity’s copying of the iQ Maximizer. The Board presumed a nexus between those objective indicia evidences and the claimed designs because it found the iQ Maximizer to be coextensive with the claims, meaning that the product was essentially the disclosed invention with unclaimed features being insignificant. The Board also found that Gamon established such a nexus regardless of the presumption. Campbell and Trinity again appealed.

Again the Federal Circuit reversed, concluding that the claimed designs would have been obvious over the prior art. In doing so, the Court confirmed the Board’s finding that the prior art and the claimed designs shared the same overall visual appearance (which Gamon did not challenge) but found that the Board’s presumption of nexus and finding of a nexus-in-fact between the claimed designs and the evidence of commercial success and praise were not supported by substantial evidence. As for the presumption, the Court considered whether the iQ Maximizer was coextensive with the claimed invention. Nexus is presumed if the objective indicia evidence is tied to a specific product that is “coextensive” with the claimed invention. The Board recognized that the claimed portions of [...]

No Summary Judgment Where Primary Reference Might Not Be “Basically the Same” as Asserted Design Patent

by McDermott Will & Emery | Apr 30, 2020 | Patents

The US Court of Appeals for the Federal Circuit found that the district court improperly resolved a genuine dispute of material fact with respect to summary judgment of invalidity for design patent obviousness because a reasonable fact finder could have concluded that the primary prior art reference did not create “basically the same” visual impression as the asserted designed patent. Spigen Korea Co., Ltd. v. Ultraproof Inc. et al., Case Nos. 19-1435; -1717 (Fed. Cir. Apr. 17, 2020) (Reyna, J.) (Lourie, J., dissented without opinion).

ITC Shines Light on DI: Complainant Can’t Aggregate Investments Across Patents, Prongs

by Alexander P. Ott | Apr 11, 2024 | Patents

Addressing a determination by its chief administrative law judge (CALJ) finding a violation of § 337, the US International Trade Commission reversed and held that the complainant had not satisfied the economic prong of the domestic industry (DI) requirement by aggregating its investment across multiple asserted patents. Certain Replacement Automotive Lamps (II), Case No. 337-TA-1292 (USITC Mar. 22, 2024).

In late 2021, Hyundai filed a complaint seeking an investigation under 19 U.S.C. § 337 based on alleged infringement of 21 design patents, each covering a different automotive headlamp or taillamp. In response, two of the proposed respondents filed a request seeking early disposition of the economic prong of the domestic industry under the Commission’s 100-day program. Hyundai filed a response opposing the 100-day program request based on the complexity of the issues. The Commission instituted the investigation and denied the 100-day program request, but when setting the procedural schedule, the CALJ scheduled an early evidentiary hearing on the economic prong of the domestic industry pursuant to the Commission’s pilot program for interim initial determinations. Following that initial hearing, the CALJ issued an interim initial determination finding that Hyundai had satisfied the economic prong of the domestic industry requirement. After the full evidentiary hearing, the CALJ issued a final initial determination finding a violation of § 337 by the respondents based on infringement of all asserted patents. The Commission decided to review both the initial and final determinations.

On review, the Commission reversed the finding that the complainant had satisfied the economic prong of the domestic industry requirement. As the Commission explained, where DI products do not have overlapping protection across common asserted patents, a complainant must treat each product as requiring a separate DI showing. The Commission cannot aggregate investments in articles covered by one patent with investments in articles only covered by a different patent. Here, because each DI product practiced only one of the asserted design patents, to satisfy the economic prong Hyundai was required to demonstrate that the investments in each product were independently significant. The Commission also held that investments in plant and equipment (§ 1337(a)(3)(A)) cannot be combined with employment of labor or capital (§ 1337(a)(3)(B)) and concluded that Hyundai had mistakenly aggregated its investments from both prongs.

Commissioner Schmidtlein filed an opinion concurring with the outcome but declining to join the majority opinion based on her view that it went beyond what was necessary to dispose of the investigation.

Distinguishing Drinkware—Provisional Priority Determined Differently in Pre- and Post-AIA Patents

by Alexander Piala, PhD | Nov 30, 2023 | America Invents Act, Patents

In a precedential final written decision, the Patent Trial & Appeal Board concluded that a patent does not need to contain a claim supported by a provisional application’s disclosure to draw priority to that provisional for prior art purposes post America Invents Act (AIA). Penumbra, Inc. v. RapidPulse, Inc., IPR2021-01466, paper 34 (PTAB Mar. 10, 2023) (designated precedential Nov. 15, 2023) (Melvin, Cotta, Wisz, APJs).

Penumbra filed an inter partes review (IPR) petition targeting a patent directed to a “thrombectomy system,” which is a system for removing blood clots in the brain. Penumbra challenged the claims on four different grounds, and each included the Tiegen reference. Therefore, the petition would fail if the Tiegen reference was not prior art.

The challenged patent was filed on July 18, 2019, and drew priority to a provisional application filed on October 24, 2018. Tiegen drew priority to two provisional applications—one dated December 12, 2018, and another dated July 24, 2018. Whether Tiegen was prior art thus depended on whether the challenged patent could draw priority to its provisional application, and whether Tiegen could draw priority to its July 24, 2018, provisional. RapidPulse challenged Tiegen on both bases.

First, the Board assessed the proper priority date for the challenged patent. The Board explained that in order for the patent to draw priority to its provisional application, that provisional application had to provide written support for the challenged patent’s claims. Penumbra argued that the challenged patent’s provisional application did not have written support for the claimed “prevent[ing] forward flow.” RapidPulse responded, arguing that the disclosure of a “minimal amount of momentum from the fluid column” disclosed the claimed “preventing forward flow.” Forward flow generates momentum from the fluid column, so minimizing momentum required preventing fluid flow, according to RapidPulse. RapidPulse also pointed to embodiments that had substantially no forward flow from the distal end of the system.

Penumbra responded by explaining that the provisional application required forward flow in some embodiments, and nothing in the specification stated that the flow should be prevented. The Board agreed, explaining that the provisional application included embodiments with forward flow, and while the provisional recited some embodiments with small amounts of forward flow, the provisional did not indicate that the low forward flow was significant. The Board observed that “one cannot disclose a forest in the original application, and then later pick a tree out of the forest.”

Having determined that the priority date of the challenged patent was July 18, 2019, the Board turned to the priority date of Tiegen. The Board distinguished the present case over Dynamic Drinkware, a 2015 US Court of Appeals for the Federal Circuit case. Dynamic Drinkware states that for prior art purposes, a prior art patent can only draw priority to a provisional application if the prior art patent contains a claim supported by that provisional application. The Board explained that Dynamic Drinkware does not apply post-AIA. Instead, the Board found that, based on the language of AIA 35 [...]
