Federal Circuit, Patent Subject Matter Eligibility

Constellation Designs v. LG Electronics — Federal Circuit Vacates § 101 Eligibility for Functional “Optimization” Claims, Affirms Eligibility for Specific Non-Uniform Constellation Claims

In a precedential opinion, the Federal Circuit drew a sharp § 101 line between functional ‘optimization’ claims that recite a result without specifying a concrete configuration and ‘constellation’ claims that recite specific non-uniform point arrangements. It vacated summary judgment of eligibility for the former and affirmed eligibility for the latter, while affirming the underlying jury verdict, willful-infringement finding, and damages award against LG.

VLSI Technology v. Intel — Federal Circuit Revives Multi-Core Patent Infringement Claims, Reverses Summary Judgment on Extraterritoriality and Prosecution Disclaimer

The Federal Circuit reversed summary judgment of noninfringement of a multi-core processor patent, holding that a pretrial stipulation establishing a 70% U.S. nexus applied to infringement — not just damages — and that prosecution history did not clearly disclaim the broader scope of apparatus claims.

Definitive Holdings v. PowerTEQ — Federal Circuit Affirms Engine Tuning Patent Invalidity Under On-Sale Bar

The Federal Circuit affirmed that U.S. Patent No. 8,458,689 — covering methods and apparatus for reprogramming automotive engine controllers — was invalid under the pre-AIA on-sale bar, holding that source code commands are not hearsay and that selling a device embodying a patented method triggers the bar even if the device’s inner workings were not publicly disclosed.

Fuente Marketing v. Vaporous Technologies — Federal Circuit Affirms TTAB Dismissal of X-Mark Trademark Opposition

The Federal Circuit affirmed the TTAB dismissal of cigar maker Fuente Marketing Ltd.s opposition to a vape-pen design mark, holding that despite overlapping goods and channels, the distinct commercial impression of Vaporous Technologies stick-figure design mark defeated likelihood of confusion with Fuentes standard-character X marks.

Federal Circuit, Utility Patent

Maxell v. Amperex Technology — Federal Circuit Reverses Indefiniteness Finding for Lithium-Ion Battery Patent

The Federal Circuit reversed a district court’s indefiniteness ruling on a lithium-ion battery patent, holding that two claim limitations are not contradictory—and therefore not indefinite—if they can both be satisfied simultaneously, even if one limitation makes an element optional while a narrowing limitation in the same claim makes that element mandatory.

Federal Circuit, Patent Subject Matter Eligibility

Chewy v. IBM — Federal Circuit Invalidates Web Advertising Patents Under § 101, Partially Reverses on Infringement

The Federal Circuit affirmed that IBM’s patent claims directed to identifying advertisements based on search queries are abstract ideas ineligible under § 101—using a conventional database to match ads with search results adds no inventive concept—while partially reversing on noninfringement, remanding one claim for further proceedings.

Federal Circuit, Utility Patent

Promptu Systems v. Comcast — Federal Circuit Reverses Claim Construction for Voice Recognition Cable TV Patents

The Federal Circuit vacated and remanded a district court judgment in a voice-recognition/cable-TV patent dispute, holding that the district court improperly narrowed several claim terms—including ‘back channel’ and ‘centralized processing station’—to specific features described in the specification rather than construing them according to their plain and ordinary meaning as understood by a skilled artisan.

Federal Circuit, Utility Patent

RAI Strategic Holdings v. Philip Morris — Federal Circuit Clarifies Written Description Standard for Claimed Ranges in Predictable Arts

The Federal Circuit vacated the PTAB’s written description rejection of e-cigarette patent claims directed to a heater-length range, holding that in predictable arts a narrower claimed range can be adequately supported by a broader disclosed range without requiring explicit disclosure of the specific narrower range—and that prior art statements made for unrelated purposes do not automatically establish motivation to combine.

Federal Circuit, Utility Patent

Weber v. Provisur Technologies — Federal Circuit Holds Confidential Operating Manuals Can Be Prior Art Printed Publications

The Federal Circuit reversed the PTAB, holding that operating manuals distributed to a limited number of customers with confidentiality notices still qualify as ‘printed publications’ and prior art under § 102, because the relevant inquiry is whether interested members of the public could locate the document through reasonable diligence—not whether the document was widely distributed.

In re GO & Associates — Federal Circuit Affirms ‘EVERYBODY VS. RACISM’ Fails to Function as Trademark

The Federal Circuit affirmed the TTAB’s refusal to register EVERYBODY VS. RACISM as a trademark for apparel, holding that the phrase functions as an informational, anti-racist message rather than as a source identifier — and confirming that widespread use of a phrase in an informational context undermines trademark registration.

Federal Circuit, International Trade Commission, Utility Patent

Roku v. ITC — Federal Circuit Holds Domestic Industry Economic Prong Can Be Satisfied by Investment in Patent-Covered Component Alone

The Federal Circuit affirmed the ITC’s finding that Universal Electronics satisfied the domestic industry requirement under Section 337 based on its investments in QuickSet technology — a patented component integrated into televisions — even though those investments did not cover the entire television product.

Federal Circuit, Utility Patent

CyWee Group v. ZTE — Federal Circuit Holds IPR Joinder New-Issue Bar Does Not Apply to Motions to Amend

The Federal Circuit held that the statutory prohibition barring time-barred, joined IPR parties from introducing new issues into a proceeding does not apply when a patent owner files a motion to amend its claims—a joined party may oppose such a motion even if it could not have raised new issues in the merits phase, because the patent owner itself opened the door to new issues by proposing amended claims.

Dexcom v. Abbott Diabetes Care — Federal Circuit Holds Forum Selection Clause Does Not Block IPR After Covenant Period Expires

The Federal Circuit affirmed that a settlement agreement’s forum selection clause requiring patent disputes to be filed in Delaware federal court did not bar Abbott from filing inter partes review petitions after the agreement’s covenant-not-to-challenge period expired—because the agreement had expressly permitted IPRs during the covenant period in certain circumstances, indicating the parties understood IPR as a distinct proceeding.

ParkerVision v. Vidal — Federal Circuit Upholds PTAB Claim Construction Based on Inventor Lexicography, Even Where It Conflicts with District Court

The Federal Circuit affirmed the PTAB’s claim construction of ‘storage element’ based on inventor lexicography in an incorporated-by-reference patent, holding that the PTAB is not bound by a conflicting district court construction and that Intel’s reply arguments were proper because they responded to a new claim construction first raised in the patent owner’s response.

Federal Circuit, Utility Patent

H. Lundbeck v. Lupin — Federal Circuit Affirms ‘Skinny Label’ Carve-Outs Block Hatch-Waxman Infringement Claims

The Federal Circuit affirmed that generic drug manufacturers who carve out patented indications from their drug labels—the so-called ‘skinny label’ strategy—do not infringe method-of-use patents covering those omitted indications under the Hatch-Waxman Act, and that brand-name companies cannot use narrow method patents to extend exclusivity beyond an approved indication.
