Fed. Cir. 24-1761 Panel Decision

DEFINITIVE HOLDINGS v. POWERTEQ

The Federal Circuit affirmed the invalidity of a patent under the pre-AIA on-sale bar, holding that a third-party sale of a device embodying the invention more than one year before the priority date renders the claims invalid regardless of whether the invention's details were publicly disclosed. The court further clarified that source code commands are not hearsay at summary judgment because they constitute instructions rather than statements of fact.

AbbVie, Inc. v. Brown

The United States Court of Appeals for the Fourth Circuit vacated a district court order denying a preliminary injunction against a Maryland statute restricting 340B drug distribution.

3rd Cir. 25-1831 Panel Decision

JOHNSON & JOHNSON, a New Jersey corporation; JANSSEN BIOTECH, INC., a Pennsylvania corporation v. SAMSUNG BIOEPIS CO. LTD., a Korean corporation

The Third Circuit affirmed the district court's denial of a preliminary injunction, holding that Janssen failed to demonstrate irreparable harm because monetary damages remain calculable despite market complexities. The court clarified that loss of market share in a breach of contract case does not automatically constitute irreparable injury absent proof that damages are practically impossible to quantify.

LEAH CAMPBELL and EMSURGCARE, EMERGENCY SURGICAL ASSISTANT v. UNITEDHEALTHCARE INSURANCE COMPANY; INSPERITY, INC and DOES, 1-10

The Ninth Circuit reversed a district court ruling that had upheld UnitedHealthcare's denial of benefits, holding that the insurer abused its discretion by failing to engage in a meaningful dialogue with the beneficiary. The court remanded the case for further proceedings, instructing the lower court to award attorneys' fees and impose statutory penalties for the insurer's failure to produce the administrative record.
