Federal Circuit Year in Review (posted 01/01/25)

In 2024, the Federal Circuit issued eighteen opinions labeled “precedential” that were related to patent law. Quotations below omit citations and internal quotations. Here is a break-down:

Anticipation / Obviousness

Cytiva Bioprocess R&D AB v. JSR Corp.: Non-obviousness of novel compounds

  • Reasonable expectation of success is not needed for motivation to combine for claims directed to an inherent property of an otherwise obvious composition or process.
  • Lead-compound analysis not required when the prior art expressly suggests the modification
  • Obvious to try is obvious under § 103 when there is a design need or market pressure exists to solve the problem and there are a finite number of identified, predictable solutions.

Palo Alto Networks, Inc. v. Centripetal Networks, LLC et al.: Motivation to combine (Patent challenger appeals from unsuccessful IPR.)

  • Patentability determinations based on obviousness must “clearly explain[] its holding or rationale regarding motivation to combine and whether the proposed combination teaches the . . . limitation.”
  • “Arguments that 'attack the disclosures of the two references individually' lack merit.”

Pfizer Inc. v. Sanofi Pasteur Inc.: Optimization of result-effective variables (Patent owner Pfizer challenges IPR holding of invalidity.)

  • If a claimed parameter would have been recognized as result-effective, the optimization of that parameter is normally obvious.

Virtek Vision Internat'l ULC v. Assembly Guidance Systems, Inc.: Motivation (Patent owner Virtek and patent challenger Aligned Vision cross-appeals IPR findings of a subset of challenged claims invalid.)

  • KSR did not do away with the requirement that there must exist a motivation to combine various prior art references in order for a skilled artisan to make the claimed invention. Here, the court quoted KSR stating “when there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense.” However, because the patent challenger failed to articulate any rationale or motivation for combining the references, it was “error of law” for PTAB to conclude that selection of one known coordinate system over another was obvious.

Prior Art

Sanho Corp. v. Kaijet Tech. Int'l Ltd.: Excluding prior art under § 102(b)(2)(B) (Patent owner Sanho appeals invalidity finding by PTAB.)

  • A non-confidential, but otherwise private sale of a product embodying an invention does not qualify as a “public disclosure” for an exemption of prior art under 35 U.S.C. § 102(b)(2)(B).

Weber v. Provisur Tech.: Printed publication requirement. (Patent challenger Weber appeals PTAB holding that Provisur's patents were not invalid.)

  • No minimum number of occasions of access is dispositive of the public accessibility inquiry.
  • It's sufficient to meet public accessibility requirement for a product manual to be obtained (1) upon purchase and (2) upon direct request.”

Design Patents

LKQ Corp. v. GM Global Tech. Operations, LLC: Design Patent Nonobviousness (Patent challenger LKQ appeals PTAB decision upholding GM's design patent on a vehicle front fender.)

  • The court overturned the Rosen-Durling test for obviousness analysis of design patents.

Claim Construction

IOENGINE, LLC v. Ingenico Inc.: Printed matter doctrine (Fed. Cir. reversed PTAB's invalidation of claims related to portable data processing devices.)

  • “Encrypted communications” and “program code” are not claimed for the content they are communicating, therefore they are not “printed matter” and the printed matter doctrine does not apply.

Pacific Biosciences of California, Inc. v. Personal Genomics Taiwan, Inc.: “For identifying a single biomolecule”

  • The PTAB's construction of the phrase, “for identifying a single biomolecule” properly required an apparatus to have the capability to characterize (determine the identity of) a biomolecule by examining that biomolecule alone, with no copies created to form an ensemble for examination.

Written Description

RAI Strategic Holdings v. Philip Morris Products: Claimed ranges (Appeal by patent owner RAI of post-grant review finding invalidity.)

  • A broader range of a variable in the application as filed provides written description support for a narrower claimed range if the disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed range. The court looked to whether the broad described range pertains to a different invention than the narrower (and subsumed) claimed range.

Procedural Determinations

ZyXEL Communications v. Unm Rainforest Innovations: Motion to Amend [MTA] Pilot Program. (ZyXEL appeals PTAB's grant to UNMRI's motion to amend and finding claim 8 nonobvious; UNMRI cross-appeals on other findings.)

  • The MTA Pilot Program is designed to allow reply briefs to address and correct errors.

SoftView LLC v. Apple Inc.: Estoppel (Patent owner SoftView appeals PTAB invalidation of all claims based on estoppel)

  • 37 C.F.R. § 42.73(d)(3)(i) is authorized by 35 U.S.C. § 316(a)(4), and the PTO therefore did not exceed its rulemaking authority in promulgating it.
  • Not patentably distinct is equivalent to substantially the same and goes beyond common law by calling for a comparison between the claims an applicant is obtaining and the finally refused or canceled claim.
  • The Board can employ principles of obviousness under KSR in determining whether a claim is patentably distinct from a prior canceled claim under 37 C.F.R. § 42.73(d)(3)(i).

Cywee Group Ltd. v. ZTE (USA), Inc.: Joint IPR petitioners (Patent owner Cywee appeals IPR decision holding original and proposed amended claims unpatentable.)

  • Where an active party to an IPR patent challenge no longer meaningfully engages in the IPR proceeding by not filing an opposition brief to a motion to amend, a passive party can file an opposition brief to a motion to amend, even where the passive party agreed to assume the primary role only if the active party ceases to participate in the IPR.

Koss Corp. v. Bose Corp.: Mootness/Issue Preclusion

  • Filing a (second) amended complaint does not nullify an interlocutory order, where therefore merges with a court's final judgment.

Platinum Optics Tech. v. Viavi Solutions: Standing (Patent challenger PTOT appeals a final written decision from IPR.)

  • A party does not need Article III standing to appear before an administrative agency, but standing is required once the party seeks review of an agency's final action in a federal court.

Speck v. Bates: Interference - (Junior party Speck appeals PTAB's decision awarding priority to Bates.)

  • A long-standing exception to section 135(b)(1), wherein an applicant can file its claim after the critical period but 'had already been claiming substantially the same invention as the patentee' during the critical period, are not time-barred. The underlying issue is . . . whether amendments to the Bates '591 application after the critical date changed the claims so that they are not substantially the same as the claims before the critical date. The Board denied Specification's motion to dismiss because it found that the later amended claims did not differ materially from the claims in other patents and patent applications Bates owned that were filed prior to the critical date because 'Speck had not directed the Board to a material limitation of the Bates involved claims that is not present in the earlier Bates claims.

Voice Tech v. Unified Patents: Appealing after Request for Rehearing (Patent owner Voice Tech appeals from PTAB finding all challenged claims obvious.)

  • An argument not repeated in a Request for Rehearing is not forfeited: “The regulatory requirement that a rehearing request 'identify all matters the party believes the Board misapprehended or overlooked' . . . simply requires the party to identify the issues it wishes to present for rehearing. . . .”

Administrative Procedure Act

Google LLC v. EcoFactor, Inc.: Claim construction and APA (Fed. Cir. vacated PTAB's claim construction.)

  • The Administrative Procedure Act requires that parties are given notice and an opportunity to address changes in claim interpretation​.
    • “The Board may adopt a claim construction of a disputed term that neither party proposes without running afoul of the APA. The Board, however, cannot, without notice and opportunity for the parties to respond, change theories midstream by adopting a claim construction in its final written description that neither party requested nor anticipated. [. . .] [B]ecause Google had notice of the contested claim construction issues and an opportunity to be heard, the Board's claim construction of Claim 1 did not violate the APA.”

Pfizer Inc. v. Sanofi Pasteur Inc.: Director Review (Patent owner Pfizer challenges IPR holding of invalidity.)

  • Failure to abide by notice-and-comment rulemaking in promulgating Director Review procedures is “harmless” unless a party can show prejudice.

Caselaw retrospectives: (04/02/21)

This is a compilation of recent caselaw and high-level subject matter and holdings taken from a recent seminar on the topic:

Supreme Court Cases

Am. Axle & Mfg., Inc. v. Neapco Holdings LLC (response due 3/31/21)

Section 101 case involving a process for balancing a vehicle axle. The issues are

  1. What standard determines whether a patent claim is “directed to” a patent-ineligible concept under step 1 of the Supreme Court’s two-step framework for determining whether an invention is eligible for patenting under 35 U.S.C. § 101; and
  2. whether patent eligibility (at each step of the Supreme Court’s two-step framework) is a question of law for the court based on the scope of the claims or a question of fact for the jury based on the state of art at the time of the patent.

Indefiniteness

7,587,446 Patent Claim 1:

1. A method of transferring media data to a network coupled apparatus, comprising:

(a) maintaining a personal information space identified with a user including media data comprising a directory of digital media files the person al information space being coupled to a server and a network; [. . .]

6,757,696 Patent Claim 1:

1. A controller for a synchronization system, comprising:

a user identifier module;

Synchronoss Techs., Inc. v. Dropbox, Inc., 987 F.3d 1358 (Fed. Cir. 2/12/21)

Claim contains impossibility. Stated the court:

“Here, the asserted claims of the ’446 patent are nonsensical and require an impossibility—that the digital media file contain a directory of digital media files. Adopting Synchronoss’s proposal would require rewriting the claims, but “it is not our function to rewrite claims to preserve their validity.” Allen, 299 F.3d at 1349. We therefore hold that the claims are indefinite as a matter of law under § 112, paragraph 2.”

Means+function. Stated the court:

“If a claim term invokes § 112, paragraph 6, we apply a two-step process for construing the term. The first step is to identify the claimed function. Williamson, 792 F.3d at 1351. The second step is to determine whether sufficient structure is disclosed in the specification that corresponds to the claimed function. Id. If the specification fails to disclose adequate corresponding structure, the claim is indefinite. Id. at 1351–52.
[. . .]
The term “user identifier module” appears in all asserted claims of the ’696 patent. . . . The corresponding text cited by Synchronoss, however, does not detail what a user identifier module consists of or how it operates.
[. . .]
It is not enough that a means-plus-function claim term correspond to every known way of achieving the claimed function; instead, the term must correspond to “adequate” structure in the specification that a person of ordinary skill in the art would be able to recognize and associate with the corresponding function in the claim. See Williamson, 792 F.3d at 1352. Because the term “user identifier module” fails in this regard, we hold that the term is indefinite and, thus, the asserted claims of the ’696 patent are invalid.

1. A method of separation of automobile shredder residue comprising the steps of:

providing automobile shredder residue as a result from a ferrous sorting recovery system;

introducing said automobile shredder residue into an auto mobile shredder residue sorting, non-ferrous recovery system;

non-magnetically sorting magnetic fuzz from said automobile shredder residue with said automobile shredder residue sorting, nonferrous recovery system;

wherein said sorted magnetic fuzz is substantially free of recyclable materials.

IQASR LLC, v. Wendt Corp., 825 Fed App'x 900 (Fed. Cir. Sept. 15, 2020

The Fed. Cir. affirmed district court finding of invalidity based on indefiniteness on claim term “magnetic fuzz” and “low susceptance microparticles.” Stated the court:

  • “In construing these terms, the court found 'magnetic fuzz' indefinite, rendering independent claim 1 (and thus the remaining claims, all dependent from claim 1) indefinite.”
  • “When a term 'has no ordinary and customary meaning,' it is a 'coined term,' raising the question of 'whether the intrinsic evidence provides objective boundaries to the scope of the term.' Iridescent Networks, Inc. v. AT&T Mobility, LLC, 933 F.3d 1345, 1353 (Fed. Cir. 2019) (citing Interval Licensing LLC v. AOL, Inc., 766 F.3d 1364, 1371 (Fed. Cir. 2014).”
  • “Ultimately, to discern 'magnetic fuzz,' an artisan has to find the low susceptance microparticles,4 and then identify which low susceptance microparticles are disassociated magnetically active microparticles. Because the multiple layers of definitions are all open-ended and non-limiting, a skilled artisan must wade through a morass of uncertainty and contradiction to get to this point. It is this word salad of inconsistent indirect definitions and examples that so flummoxed the district court. We agree with the district court that '[t]he lack of a meaningful description of what constitutes magnetic fuzz prevents a person skilled in the art from knowing when it is present and how to address it.' Decision at *7. A technical degree or industry experience does not confer the ability to transcend patent ambiguity.”
  • “IQASR argues that magnetic fuzz is definite because 'the skilled artisan would presumably be familiar with what clogged the non-ferrous recovery system and would thereby recognize magnetic fuzz.' Appellant’s Br. 43 (emphasis omitted). But this asserts a subjective view of the claims that improperly allows 'the

scope [to] vary from day-to-day and from person-to-person,' providing 'a moving target that may change over time.' Icon Health & Fitness, Inc. v. Polar Electro Oy, 656 F. App’x 1008, 1016 (Fed. Cir. 2016).

Infinity Computer Prods. v. Oki Data Ams., Inc., 987 F.3d 1053 (Fed. Cir. Feb. 10, 2021)

The court here held that “Indefiniteness may result from inconsistent prosection history statements where the claim language and specification on their own leave uncertainty that, if unresolved, would produce indefiniteness.”
