Inguran v. ABS Global — Federal Circuit Holds Judgment on Direct Infringement Does Not Preclude Later Induced Infringement Suit

The Federal Circuit reversed the dismissal of an induced patent infringement suit on res judicata grounds, holding that a prior judgment on direct infringement claims does not preclude a subsequent suit for induced infringement when the induced infringement claims are based on different operative facts and were not litigated in the first action.

Parus Holdings v. Google — Federal Circuit Holds PTAB May Disregard Evidence Incorporated by Reference in Violation of Procedural Rules

The Federal Circuit affirmed PTAB’s decision to disregard Parus Holdings’ evidence in IPR proceedings, holding that a patent owner’s attempt to incorporate arguments by reference through voluminous exhibits violates PTAB procedural rules and the APA does not require the Board to overlook that violation.

Blue Gentian v. Tristar Products — Federal Circuit Upholds Co-Inventor Correction for Expandable Hose Patent

The Federal Circuit affirmed that a nonparty who shared key design elements for an expandable hose with the named inventor at a pre-filing meeting was a co-inventor who should have been listed on the patents, and that his testimony was adequately corroborated by physical prototypes and documentary evidence—requiring correction of inventorship on all asserted patents.

Yita v. MacNeil IP — Federal Circuit Reverses PTAB’s Reliance on Secondary Considerations Tied Only to Known Prior Art Feature

The Federal Circuit reversed the PTAB’s reliance on commercial success as a secondary consideration of nonobviousness for car floor mat patents, holding that evidence of commercial success must be linked to the claimed combination as a whole, not to a single feature that was already present in the prior art—otherwise there is no nexus and the secondary consideration carries no weight.

Sanofi-Aventis v. Mylan Pharmaceuticals — Federal Circuit Reverses PTAB on Analogous Art Test for Drug Delivery Patent

The Federal Circuit reversed the PTAB’s obviousness ruling on a drug delivery device patent, holding that the Board misapplied the analogous art test by comparing a prior art reference to another prior art reference rather than to the challenged patent—an IPR petitioner bears the burden of showing that each prior art reference is analogous to the patent being challenged, not to other references.

HIP v. Hormel Foods — Federal Circuit Clarifies ‘Significant Contribution’ Standard for Joint Inventorship

The Federal Circuit reversed a district court’s addition of a joint inventor to a bacon-precooking patent, holding that contributing a preheating concept—when that concept was already known and not the novel element of the claimed invention—is an ‘insignificant’ contribution that does not satisfy the requirements for joint inventorship under the Pannu factors.

Arbutus Biopharma v. ModernaTX — Federal Circuit Affirms Invalidity of mRNA Lipid Nanoparticle Patent

The Federal Circuit affirmed that Arbutus Biopharma’s patent on stable nucleic acid-lipid particles (SNALPs) with non-lamellar morphology was inherently anticipated by an earlier Arbutus patent, holding that when the same formulation process disclosed in both patents naturally produces the claimed morphological structure, anticipation is established even without an explicit description of that structure in the earlier patent.

Intel v. PACT XPP Schweiz — Federal Circuit Reverses PTAB on Motivation to Combine in Multiprocessor Cache Patent

The Federal Circuit reversed the PTAB’s finding of no obviousness, holding that when two prior art references address the same technical problem and one provides a known technique for solving it, a skilled artisan would be motivated to combine them—the Board’s contrary conclusion contradicted the very logic of the KSR ‘known-technique’ rationale.

Regents of University of Minnesota v. Gilead Sciences — Federal Circuit Affirms Invalidity of Antiviral Drug Patent for Lack of Written Description

The Federal Circuit affirmed the PTAB’s ruling that the University of Minnesota’s antiviral drug patent—directed to phosphoramidate prodrugs of nucleoside derivatives—lacked adequate written description support for its broad genus claims, because the patent’s specification disclosed only a ‘laundry list’ of chemical moieties without adequately describing the full scope of the compounds being claimed.

Minerva Surgical v. Hologic — Federal Circuit Holds Trade Show Demonstration of Medical Device Prototype Triggers Public Use Bar

The Federal Circuit affirmed that Minerva Surgical’s demonstration of 15 fully functional endometrial ablation device prototypes at an industry trade show—more than a year before the patent’s priority date—triggered the public use bar of pre-AIA § 102(b) and invalidated the asserted patent claims, because the prototypes embodied every claim limitation and were demonstrated to sophisticated, unconstrained observers.

Grace Instrument v. Chandler Instruments — Federal Circuit Vacates Indefiniteness Finding, Reaffirms Primacy of Intrinsic Record Over Dictionary Definitions

The Federal Circuit vacated a district court’s indefiniteness finding for a viscometer patent, holding that the intrinsic record — not dictionary definitions — governs claim construction, and that terms of degree are not indefinite when the specification provides adequate context for a skilled artisan.

Genentech, Inc. v. Sandoz Inc. (2022) — Federal Circuit Holds Generic Drug Label Need Not Actively Promote Infringing Use to Support Inducement

The Federal Circuit affirmed that Sandoz’s generic pirfenidone label would not induce infringement of Genentech’s method-of-treatment patents, and also upheld invalidity of the liver function test patents as obvious, clarifying the inducement standard for drug labels in Hatch-Waxman litigation.

Corcept Therapeutics v. Teva — Federal Circuit on Method of Treatment Patent Eligibility for Drug-Disease Interactions

The Federal Circuit affirmed infringement of Corcept Therapeutics’ method-of-treatment patents covering combination therapy using mifepristone with a strong CYP3A inhibitor — finding that Teva’s ANDA label induced infringement and rejecting Teva’s challenge to the skinny label carve-out strategy Corcept had prevented through its method claims.

Kamstrup A/S v. Axioma Metering UAB — Federal Circuit Holds Product-By-Process Language Does Not Confer Patentability Without Structural Distinction from Prior Art

The Federal Circuit affirmed that product-by-process claim language — which defines a product in terms of the process used to make it — does not impart patentable weight unless the claimed process produces a product that is structurally and functionally different from the prior art.

Realtime Adaptive Streaming LLC v. Netflix, Inc. — Federal Circuit Upholds Attorneys’ Fees Sanction for Forum-Shopping Through Voluntary Dismissal and Refiling

The Federal Circuit affirmed an award of attorneys’ fees under the court’s inherent equitable powers, holding that a patent owner’s voluntary dismissal from one district followed immediately by refiling the same case in a different district constituted bad-faith forum shopping that warranted sanctions.

Koninklijke Philips N.V. v. Thales DIS AIS USA LLC — Federal Circuit Holds Speculative Customer Concerns Are Insufficient to Show Irreparable Harm for Preliminary Injunction

The Federal Circuit affirmed denial of a preliminary injunction, holding that speculative harms and generalized customer concerns about potential future harm do not constitute the concrete evidence of irreparable injury required to support preliminary patent injunctive relief.

Centripetal Networks v. Cisco Systems — Federal Circuit Vacates $2.75 Billion Award After Judge’s Failure to Recuse Over Spouse’s Stock Ownership

The Federal Circuit vacated a $2.75 billion patent infringement judgment against Cisco, holding that the trial judge was disqualified from hearing the case after discovering his wife owned Cisco stock — placing the stock into a blind trust did not satisfy the federal recusal statute’s divestiture requirement.
