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.

PTO Proposes Patent Fee Increases

by Amol Parikh | May 4, 2023 | Patents

The US Patent & Trademark Office (PTO) announced proposed patent fee increases. Patent fees would increase by about 5% across the board because of inflation.

Certain fees would be increased by substantially more than the 5% inflationary increase to reduce subsidization from other fee sources. For example, the overall design patent fees would increase by 48%, based on a 27% increase in filing, search and examination fees and a 76% issue fee increase. The PTO also proposes a 100% increase in the excess claim fee for each claim over 20, and a 25% increase in the fee for each independent claim over three. Because the costs of reviewing patent term extensions is complex, the PTO proposes fee increases of 196% to 468%. The PTO also proposes a fee of $500 for filing an After Final Consideration Pilot (AFCP) 2.0 request, and new fees for filing an information disclosure statement (IDS) that causes the number of applicant-provided citations to exceed 50, 100 or 200 citations, respectively.

To offset the loss of future maintenance fee payments, the PTO proposes fees of $1,500 for continuing applications filed more than three years from the earliest benefit date and $3,000 for continuing applications filed more than seven years from the earliest benefit date.

Other proposed fee increases are intended to expedite the patent examination process. For example, the PTO proposes a 25% increase in the fee for a second request for continued examination (RCE) and an 80% increase for a third or subsequent RCE. The fee for a terminal disclaimer filed after the first action on the merits and before a final rejection would increase by 194%. After a final rejection or notice of allowance, the fee would increase by 371%. On or after a notice of appeal, the increase would be 547%, and the proposed increase for filing a terminal disclaimer in an issued patent would be 724%.

The PTO further proposes increasing Patent Trial & Appeal Board America Invents Act (AIA) trial fees by 25%. The PTO also proposes new fees for inter partes review (IPR) and post grant review (PGR) petitions that exceed the word count limits. For example, the PTO proposes a 50% higher fee for petitions that exceed the word count limit by up to 50%, and a 100% higher fee for those that exceed the limit by up to 100%.

A public hearing is scheduled for May 18, 2023. Those wishing to present oral testimony at the hearing must submit a written request by May 11, 2023. Written comments on the proposed fees will be accepted until May 25, 2023.

The PTO anticipates that the fee changes will be implemented around January 2025.

More details, including a complete list of the proposed fee increases, can be found on the PTO website.

Branding Function Patent Yet Another 1[01] to Bite the Dust

by Thomas DaMario | Apr 20, 2023 | Patents

Addressing the patentability of claims directed to digital image branding functions, the US Court of Appeals for the Federal Circuit affirmed a district court’s determination that claims across three related patents were invalid under 35 U.S.C. § 101 for lacking patent-eligible subject matter. Sanderling Mgmt. Ltd. v. Snap Inc., Case No. 21-2173 (Fed. Cir. Apr. 12, 2023) (Chen, Cunningham, Stark, JJ.)

Sanderling owns three patents, each titled “Dynamic Promotional Layout Management and Distribution Rules.” The three patents share a common specification and are generally directed to a method using distribution rules to load digital imaging branding functions to users when certain conditions are met. The specification explains that a distribution rule is “a rule used in determining how to target a group of end users, for instance, a rule that determines that only a group of end users having certain characteristics and/or match a certain requirement.”

Sanderling asserted each of the three patents against Snap in the Northern District of Illinois. Snap moved to transfer venue to the Central District of California and to dismiss the case under Fed. R. Civ. P. 12(b)(6) for failure to state a claim based on the allegation that the asserted patents’ claimed ineligible subject matter under § 101. After the case was transferred, the Central District of California found the claims patent ineligible and granted Snap’s motion to dismiss. Sanderling appealed.

The Federal Circuit reviewed the decision by engaging in the two-step Alice framework for subject matter eligibility. Under step one, the Court determined that the claims were directed to the abstract idea of providing information—in this case, a processing function—based on meeting a condition (e.g., matching a GPS location indication with a geographic location). The Court explained that for computer-related inventions, the relevant question is whether the claims are directed to an improvement to computer functionality or to an abstract idea. The Court found that the claims in issue were not directed to an improvement in computer functionality, but instead to the use of computers as a tool—specifically, a tool to identify when a condition is met and then to distribute information based on satisfaction of that condition.

Even if directed to an abstract idea, patent claims may still be eligible under step two of the Alice framework if there are additional features that constitute an inventive concept. The Federal Circuit, however, found that the claims failed this step also. The Court explained that if a claim’s only inventive concept is the application of an abstract idea using conventional and well-understood techniques, the claim has not been transformed into a patent-eligible application of an abstract idea. The distribution rule of the asserted claims was just that: the application of the abstract idea using common computer components. Accordingly, the Court affirmed the district court’s decision that the patent claims were invalid under § 101.

Practice Note: On appeal, Sanderling argued that the district court erred at step one of the Alice analyses by failing to construe certain claim terms that were allegedly crucial to the determination. [...]

Patent Law Principles Apply to Claim Scope: Orange Book Delisting and Listing and Regulations

by Benjamin Ediger, Ph.D. | Mar 9, 2023 | Patents

The US Court of Appeals for the Federal Circuit ordered that the only Orange Book patent asserted in a lawsuit must be delisted since its claims were directed to the computer-implemented distribution system and not a method of use. Jazz Pharms., Inc. v. Avadel CNS Pharms., LLC, Case No. 23-1186 (Fed. Cir. Feb. 24, 2023) (Lourie, Reyna, Taranto, JJ.)

Jazz Pharmaceuticals holds a new drug application (NDA) for Xyrem, an oral sodium oxybate solution prescribed to help those with certain narcolepsies manage cataplexy. Sodium oxybate itself is no longer covered by patents because it has been used in relation to narcolepsy since the 1960s. For this reason, Jazz built its patent portfolio around Xyrem’s formulation, use and distribution.

Jazz uses a single-pharmacy distribution system for Xyrem, known as a risk evaluation mitigation strategy (REMS). Implementing REMS was a condition of Xyrem’s US Food & Drug Administration (FDA) approval because it mitigates safety risks of dangerous active pharmaceutical ingredients such as sodium oxybate. One of Jazz’s patents is directed to this REMS distribution system. Abbreviated New Drug Application (ANDA) 505(b)(2) NDA (Hybrid NDA) approval is similarly conditioned on implementing a REMS that is sufficiently comparable to any that the NDA holder must implement. The FDA eventually determined that single-pharmacy systems were unnecessary for Xyrem and potentially detrimental.

Avadel submitted a hybrid NDA for a drug that requires only a single nightly dose, unlike Xyrem, which requires a patient to wake up during the night to ingest a second dose. Avadel’s application also proposed a more lenient REMS that utilizes multiple pharmacies. In view of these differences, Avadel believed that it could avoid a lengthy FDA approval process because all of Jazz’s Xyrem Orange-Book-listed patents seemed addressable without making any Paragraph IV certifications. As for the REMS patent, Avadel filed a statement under 21 U.S.C. § 355(b)(2)(B) because the patent was listed as claiming a method of use and Avadel was not seeking approval for the REMS system to which that patent’s claims were directed.

Jazz sued Avadel asserting seven patents, of which the REMS patent was the only Orange-Book-listed patent. Avadel asserted a counterclaim requesting that the district court order Jazz to delist the REMS patent from the Orange Book. The district court subsequently held a Markman hearing finding that the REMS patent’s claims were directed to a system and not a method. The district court granted Avadel’s motion for judgment on the pleadings, finding that the REMS patent did not claim “the drug for which the application was approved” and thus had to be delisted from the Orange Book. Jazz appealed.

Jazz argued that because the FDA permitted the REMS patent to be Orange Book listed, Avadel was prohibited from availing itself of the statutory delisting provision. The Federal Circuit disagreed, concluding that the language of the delisting provision was only concerned with whether a listed patent met the provisions’ conditions at the time of the triggering litigation.

Jazz also argued that there was no evidence that Congress imported patent-law [...]

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 [...]

ANDA Filing Alone Insufficient for Induced Infringement of Method Patent

by Tessa Kroll | Jan 5, 2023 | Patents

The US Court of Appeals for the Federal Circuit upheld a district court’s findings of invalidity and noninfringement in a Hatch-Waxman case involving two sets of method patents directed to modulating dosages of pirfenidone, a drug used to treat idiopathic pulmonary fibrosis (IPF). The Court found that the first set of patents were obvious over the prior art and standard medical practice, while the second set were not directly infringed in light of actual physician prescription practice. Genentech, Inc. v. Sandoz Inc., Case No. 22-1595 (Fed. Cir. Dec. 22, 2022) (Newman, Lourie, Prost, JJ.) (Newman, J., dissenting).

Sandoz submitted two abbreviated new drug applications (ANDAs) for approval to market a generic version of pirfenidone, which Genentech sells under the brand name Esbriet®. Genentech sued Sandoz under the Hatch-Waxman Act, asserting that Sandoz’s generic version would induce infringement of two sets of patents: one directed to modifying dosages of pirfenidone in patients with abnormal liver biomarkers (LFT patents), and the other directed to avoiding adverse interactions in patients also taking fluvoxamine (DDI patents).

The LFT patents are directed to methods of administering pirfenidone to a patient who has exhibited Grade 2 abnormalities in liver function biomarkers alanine transaminase (ALT) and/or aspartate transaminase (AST) in response to pirfenidone. The LFT patents generally recite the following administration options:

Temporarily reducing the dose before returning to the full dose
Maintaining the full dose
Reducing the dose
Temporarily discontinuing pirfenidone before returning to the full dose
Temporarily discontinuing pirfenidone before returning to a reduced dose.

Sandoz’s proposed label included a “Dosage Modification due to Elevated Liver Enzymes” section, which stated that if a patient exhibits grade 2 elevations of ALT and/or AST, “[t]he full daily dosage may be maintained, if clinically appropriate, or reduced or interrupted (e.g., until liver chemistry tests are within normal limits) with subsequent re-titration to the full dosage as tolerated.” Genentech argued that these instructions constituted induced infringement of the LFT patents. The district court disagreed and held that the LFT patents were obvious over the prior art and standard medical practice and that the defendant would not induce infringement because the labels “merely described” the infringing uses but did not recommend them.

The DDI patents are directed to methods for avoiding adverse interactions between pirfenidone and fluvoxamine and generally involve the steps of discontinuing fluvoxamine or modifying the dose of pirfenidone and continuing fluvoxamine. Sandoz’s proposed label warned of the adverse interactions between pirfenidone and fluvoxamine and stated that fluvoxamine should be discontinued prior to administering pirfenidone or the dose of pirfenidone should be reduced. Genentech similarly argued that these instructions constituted induced infringement of its DDI patents, but the district court held that there was insufficient evidence for infringement because Genentech had not shown that a patient would actually be prescribed both pirfenidone and fluvoxamine in practice.

Genentech appealed the district court’s holdings with respect to both the LFT and DDI patents.

LFT Patents

The Federal Circuit first observed that “varying doses in response to the occurrence [...]

Delayed Disclaimer: Patent Owner Arguments Made during IPR Not a Claim Limiting Disclaimer in That Proceeding

by Aashish Kapadia | Nov 29, 2022 | Patents

Repeating a conclusion from an earlier non-precedential opinion in VirnetX, the US Court of Appeals for the Federal Circuit held that the Patent Trial & Appeal Board (Board) need not accept a patent owner’s arguments as a disclaimer in the very same inter partes review (IPR) proceeding in which those arguments are made. CUPP Computing AS v. Trend Micro Inc., Case Nos. 2020-2262, 2020-2263, 2020-2264, at *11 (Fed. Cir. Nov. 16, 2022) (Dyk, Taranto, Stark, JJ.)

CUPP Computing is the owner of three related patents each entitled “systems and methods for providing security services during power management mode.” After CUPP sued Trend Micro for patent infringement, Trend Micro filed petitions for IPR against all three patents, asserting that several claims of CUPP’s patents were obvious over two prior art references. The Board instituted all three IPR and found all challenged claims unpatentable as obvious. CUPP appealed.

The Federal Circuit affirmed the Board’s conclusions. The principal issue concerned CUPP’s argument that the Board erred in claim construction. In CUPP’s view, all of the evidence required the claimed “security system processor” be remote from a “mobile device processor.” The Court rejected CUPP’s arguments. Starting with the claims, the Court found that they simply required that the two processors be different. Although some claims required the security system to send a wake signal to or communicate with the mobile device, that language did not support CUPP’s remoteness construction. As the Court explained, just as an individual can send a note to oneself via email, a unit of the mobile device can send signals to and communicate with the same device. Indeed, some of the claims teach communication via an internal port of the mobile device, which was consistent with a preferred embodiment disclosed in the specification in which the two processors could be within the same mobile device.

The Federal Circuit then addressed CUPP’s disclaimer arguments. The Court agreed with the Board that CUPP’s statements made during the original prosecution were far from clear and unmistakable, being susceptible to several reasonable interpretations that are contrary to CUPP’s construction. The Court also agreed with the Board that CUPP’s arguments during the Trend Micro IPRs do not qualify as a disclaimer for purposes of claim construction. While a disclaimer made during an IPR proceeding is binding in subsequent proceedings, the “Board is not required to accept a patent owner’s arguments as disclaimer when deciding the merits of those arguments.”

As the Federal Circuit explained, expanding the application of disclaimers to the proceedings in which they are made—as CUPP proposed—is rife with problems. IPR proceedings are more similar to district court litigation than they are to initial examination, and it is well established that disclaimers in litigation are not binding in the proceeding in which they are made. Further, CUPP’s proposal would effectively render IPR claim amendments unnecessary, as patent owners would be free to change the scope of their claims retrospectively without regard to the protections provided by the IPR claim amendment process, such as [...]

EU Unified Patent Court Announces Intent to Launch on April 1, 2023

by Dr. Henrik Holzapfel and Paul Devinsky | Oct 20, 2022 | EU Update, Patents

The EU Unified Patent Court (UPC) announced a launch date of April 1, 2023, however, the announced date should be regarded as a statement of intent for it could change. The launch timing has been the subject of various delays and setbacks, several due to unresolved legal issues. The UPC has also published an almost final list of judges. German Federal Court of Justice Judge Klaus Grabinski, who played a key role in drafting the UPC Rules of Procedure, will head the UPC. The majority of UPC judges will only be engaged with their UPC activities part-time (about 50% or 20% of their total work commitment).

The UPC judges are set to receive special training starting in March 2023, only one month prior to the announced launch date of the UPC, leading many to doubt that the April 1 date will be met. Once the new court is operational, owners of European patents will be able to litigate patent disputes across most EU Member States in a single proceeding, eliminating the need to proceed on a country-by-country basis.

Assuming the announced launch date is maintained, the “sunrise period” before the UPC becomes fully operational will commence on January 1, 2023. This sunrise period will last for three months, during which patent owners that do not wish for their existing European patents to be subject to UPC jurisdiction may opt out of such jurisdiction by filing a formal notification to that effect. The European Patent Office has also announced that during the sunrise period, European patent applicants whose applications are ready for grant will, if they wish, be able to delay the formal grant of the application until the UPC becomes operational so that unitary patent protection can be obtained.

The UPC has issued an implementation roadmap for events leading up to the entry into force of the UPC Agreement, with the court opening its doors and starting to receive cases as of April 1, 2023.

PTO Requests Comments on Initiatives to Ensure Patent Robustness, Reliability

by Amol Parikh | Oct 13, 2022 | Patents

The US Patent & Trademark Office (PTO) is seeking public input and guidance on proposed initiatives directed at bolstering the robustness and reliability of patents. The request for comments was spurred in part by US President Joe Biden’s July 9, 2021, executive order on Promoting Competition in the American Economy, and a June 8, 2022, letter from Senators Leahy, Blumenthal, Klobuchar, Cornyn, Collins and Braun raising concerns about patent thickets.

The PTO identified four broad topics and initiatives that it is considering:

Prior Art Searching
Support for Patent Claims
Request for Continued Examination (RCE) Practice
Restriction, Divisional, Rejoinder and Non-Statutory Double Patenting Practice.

The PTO seeks comments on 11 main questions and several sub-questions. The first five questions are directed to the PTO initiatives while questions six through 11 address concerns raised by the senators.

PTO Initiatives

How should the PTO facilitate an applicant’s submission of prior art that is not accessible in the Patents End-to-End Search system (e.g., “on sale” or prior public use)?

How, if at all, should the PTO change claim support requirements and/or continuation practice?

How, if at all, should the PTO change RCE practice?

How, if at all, should the PTO limit or change restriction, divisional, rejoinder and/or non-statutory double patenting practice?

Provide any other input on any of the proposals listed under the PTO initiatives.

Senator Inquiries

How would eliminating terminal disclaimers, thus prohibiting patents that are obvious variants of one another, affect patent prosecution strategies and overall patent quality?

Should patents that are tied together by a terminal disclaimer because of an obviousness-type double patenting rejection stand or fall together if their validity is subsequently challenged?

Should the PTO require a second look by a team of patent quality specialists before issuing a continuation patent on a first office action?

Should there be heightened examination requirements for continuation patents?

Should the PTO implement a rule change that requires any continuation application to be filed within a set timeframe of the ultimate parent application?

If filing fees were increased to cover the actual cost of obtaining a patent, would this increase patent quality? And if the fees for continuation applications were increased, would applicants be less likely to file continuations for obvious variants?

Among the proposals under consideration are whether to require applicants to identify corresponding support in the original disclosure for each claim in a continuation application, whether applications should be reassigned to a different examiner after a set number of RCEs are filed, whether the PTO should adopt the unity of invention standard, and whether divisionals should be filed within a set time period.

Comments must be received by January 3, 2023, to ensure consideration.
