Federal Circuit patent decisions

Federal Circuit, Utility Patent

Actelion Pharmaceuticals v. Mylan — Federal Circuit Vacates Infringement Judgment, Requires Extrinsic Evidence for pH Claim Construction

The Federal Circuit vacated an infringement judgment in an ANDA case involving pulmonary hypertension drug patents, holding that the district court erred by construing ‘a pH of 13’ based solely on intrinsic evidence when the parties submitted competing extrinsic evidence—including textbooks explaining how chemists understand significant figures in pH values—that the court was required to consider.

Great Concepts v. Chutter — Federal Circuit Rules Fraudulent Incontestability Declaration Cannot Cancel a Trademark Registration

The Federal Circuit reversed the TTAB’s cancellation of Great Concepts’ DANTANNA’S restaurant trademark, holding that filing a fraudulent Section 15 incontestability declaration does not give the Board authority to cancel the underlying registration — fraud after registration has limited remedies under the Lanham Act.

Design Patent, Federal Circuit

Columbia Sportswear v. Seirus — Federal Circuit Rules Design Patent Comparison Prior Art Must Match the Same Article of Manufacture

In a precedent-setting design patent case, the Federal Circuit held that comparison prior art used to defend against infringement must be drawn from the same article of manufacture claimed in the design patent — prior art from a different type of product cannot be used to confuse the ordinary observer comparison.

Federal Circuit, Utility Patent

Netflix v. DivX — Federal Circuit Clarifies ‘Field of Endeavor’ Standard for Analogous Art in Obviousness Analysis

The Federal Circuit held that the PTAB applied an unduly strict standard when it rejected Netflix’s analogous art argument in an IPR, ruling that petitioners need not perfectly articulate the ‘field of endeavor’ in magic words—what matters is whether the prior art reference and the challenged patent share the same substantive technical field.

Federal Circuit, Utility Patent

Volvo Penta v. Brunswick — Federal Circuit Vacates PTAB Obviousness Finding for Failure to Properly Weigh Secondary Considerations

The Federal Circuit vacated the PTAB’s finding that Volvo Penta’s stern drive patent was obvious, holding that the Board improperly dismissed evidence of secondary considerations—including copying, commercial success, and industry praise—when competitors’ own recognition that the product’s success came from the unique patented features established the required nexus.

Federal Circuit, Utility Patent

Rembrandt Diagnostics v. Alere — Federal Circuit Clarifies When IPR Petitioner Reply Arguments Are Permissible

The Federal Circuit affirmed that IPR petitioner reply arguments expanding on cost and time savings as a motivation to combine were not impermissibly new—they properly responded to the patent owner’s opposition and were a fair extension of the efficiency rationale raised in the original petition—and held that a patent owner waives a ‘new theories’ objection by making only a general objection without identifying which theories are allegedly new.

Federal Circuit, Utility Patent

In re Float’N’Grill — Federal Circuit Limits Reissue Patents to Inventions Explicitly Disclosed in the Original

The Federal Circuit affirmed rejection of a reissue patent application that tried to broaden claims beyond the original patent’s single disclosed embodiment, holding that reissue claims must be directed to the same invention explicitly described in the original patent—not to undisclosed alternatives to elements the inventor treated as necessary to the invention.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Patent Subject Matter Eligibility

Sanderling Management v. Snap — Federal Circuit Invalidates Promotional Content Distribution Patents Under § 101

The Federal Circuit affirmed that patents claiming a method for distributing digital promotional content—loading branding images when a user’s GPS location matches a specified geographic area—are directed to the abstract idea of providing information based on meeting a condition, and contain no inventive concept that transforms the claims into patent-eligible subject matter.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility 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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.

Federal Circuit, Patent Subject Matter Eligibility

ChromaDex v. Elysium Health — Federal Circuit Holds Isolated Vitamin B3 Supplement Patent Invalid Under § 101

The Federal Circuit affirmed that patent claims directed to isolated nicotinamide riboside (NR)—a form of vitamin B3 found naturally in cow’s milk—are directed to a natural phenomenon and ineligible under § 101, because the claims effectively read on milk with only the isolation step as a difference, and that step adds no inventive concept.

Federal Circuit, Utility Patent

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.

Federal Circuit, Utility Patent

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.
