The Federal Circuit vacated and remanded the district court’s summary judgement of noninfringement, finding that the lower court had improperly construed the claim term “pull cord.” The district court had erroneously limited the term to a directly pulled cord that lacks a handle. The Federal Circuit determined that these restrictions were unsupported by the intrinsic evidence and directed the district court to apply the correct claim construction in accordance with the Federal Circuit’s guidance and redetermine infringement using the correct claim construction.Continue Reading Federal Circuit Vacates Summary Judgement: Limitations from Specifications Should Not Have Been Imported Into the Claims

Cir. 2025) – On March 7, 2025, the Federal Circuit affirmed the Patent Trial and Appeal Board’s inter partes review (“IPR”) decisions invalidating all claims of three AliveCor patents. Previously, the International Trade Commission (“ITC”) had found certain Apple Watch products infringe two of the three patents. Continue Reading You Snooze, You Lose: Federal Circuit Emphasized Once Again the Importance of Preserving Issues for Appellate Review

In Restem, LLC v. Jadi Cell, LLC, No. 2023-2054 (Fed. Cir. Mar. 13, 2025), the Federal Circuit upheld the Patent Trial and Appeal Board’s decision holding that U.S. Patent No. 9,803,176 (“the ’176 patent”) was not inherently anticipated by a prior art process, because the prior art process did not inevitably result in the claimed cell marker expression profile.Continue Reading Federal Circuit Clarifies Anticipation Analysis for Product-By-Process Claims

In a significant decision, the Federal Circuit reversed the U.S. International Trade Commission’s (ITC) finding that claims of U.S. Patent No. 10,508,502 (502 Patent) were invalid under 35 U.S.C. § 101. The opinion addresses critical issues in patent eligibility jurisprudence, particularly regarding composition-of-matter claims and provides additional clarity for patent owners facing § 101 challenges.Continue Reading Federal Circuit Clarifies § 101 Patent Eligibility for Composition-of-Matter Claims

The U.S. Supreme Court has once again been urged to revisit 35 U.S.C. § 101, the statute governing patent eligibility. Audio Evolution Diagnostics, Inc. (AED) filed a petition for writ of certiorari, challenging the Federal Circuit’s summary affirmance under Rule 36 of a ruling that invalidated its patents under the Alice/Mayo framework. Should the SCOTUS take up the case, this presents an opportunity for the Court to clarify the boundaries of patent eligibility and address concerns over the Federal Circuit’s handling of such cases.Continue Reading Patent Eligibility: The Call for Supreme Court Clarity and for an End to Summary Affirmances

The U.S. Copyright Office’s January 2025 report on AI and copyrightability reaffirms the longstanding principle that copyright protection is reserved for works of human authorship. Outputs created entirely by generative artificial intelligence (AI), with no human creative input, are not eligible for copyright protection. The Office offers a framework for assessing human authorship for works involving AI, outlining three scenarios: (1) using AI as an assistive tool rather than a replacement for human creativity, (2) incorporating human-created elements into AI-generated output, and (3) creatively arranging or modifying AI-generated elements.Continue Reading The Copyright Office’s Latest Guidance on AI and Copyrightability

Novartis Pharmaceuticals Corporation v. Torrent Pharma Inc., No. 23-2218 (Fed. Cir. 2025) — On January 10, 2025, the Federal Circuit reversed the district court’s opinion that claims of a Novartis patent are invalid for lack of adequate written description, but affirmed the district court’s finding that the claims were not proven invalid for lacking enablement or being obvious over the asserted prior art. The Federal Circuit emphasized that the proper analysis for enablement and written description challenges is focused on the claims and after-arising technology need not be enabled or described in the specification—even when the after-arising technology is found to infringe the claims because the issues of patentability and infringement are distinct. “It is only after the claims have been construed without reference to the accused device that the claims, as so construed, are applied to the accused device to determine infringement.”Continue Reading Federal Circuit Highlights the Importance of Separating Claim Construction and Infringement Analysis When Dealing with After-Arising Technology
