Google LLC v. Wildseed Mobile, LLC: Date Argued: February 4th, 2026; Docket Number: 24-2178

Case Summary: In Google LLC v. Wildseed Mobile, LLC (Docket No. 24-2178), argued before the U.S. Court of Appeals for the Federal Circuit on February 4, 2026, the case involves a complex patent dispute following a rare split decision from the Patent Trial and Appeal Board (PTAB).The factual record centers on several patents held by Wildseed Mobile relating to mobile advertising and user interface technologies, which Wildseed claimed were infringed by Google’s YouTube platform and Android advertising services. In the underlying administrative proceedings, Google successfully challenged the validity of these patents, leading the PTAB to issue a final written decision that invalidated key claims as obvious over prior art. However, the PTAB’s decision was notably non-unanimous, featuring a rare dissent from an administrative patent judge who argued that certain unique aspects of Wildseed’s "time-shifted" advertising innovations were not properly accounted for in the majority’s obviousness analysis. On appeal, the primary factual and legal dispute focuses on whether the PTAB correctly applied the standards for novelty and non-obviousness and whether the board’s findings were supported by substantial evidence.
