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 [...]

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 [...]

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).
