Finesse Wireless v. AT&T Mobility (Fed. Cir., September 24, 2025) 2024-1039

This episode concerns an opinion from the United States Court of Appeals for the Federal Circuit regarding the case of Finesse Wireless LLC v. AT&T Mobility LLC and others. The court addresses an appeal by the defendants, AT&T and Nokia, against a district court's denial of Judgment as a Matter of Law (JMOL) regarding the noninfringement of U.S. Patent Nos. 7,346,134 and 9,548,775, which relate to methods for mitigating intermodulation product interference in radios. The Federal Circuit ultimately found that the jury's verdict of infringement for both patents was not supported by substantial evidence, particularly pointing to contradictory expert testimony regarding the patented methods. Consequently, the court reversed the denial of JMOL for noninfringement of all asserted claims and vacated the substantial damages award of over $166 million. The ruling details the technical reasons for noninfringement, focusing on the lack of evidence that the accused radios performed key claim limitations in both patents.
