The Verdict & Legal Analysis
Outcome
The Federal Circuit **affirmed** the prior ruling against Wireless Discovery LLC in a per curiam decision from Judges Chen, Stoll, and Cunningham. The appeal was dismissed, ending a 482-day legal battle without a damages award or injunctive relief in favor of the plaintiff.
Key Legal Issues
The per curiam decision reinforces the Federal Circuit’s consistent scrutiny of location-based network patents. Location-based patent litigation often turns on claim construction disputes and §101 subject matter eligibility challenges under *Alice Corp. v. CLS Bank International*. While specific grounds weren’t detailed, the affirmance indicates the lower court’s reasoning, likely around these issues, was well-grounded and withstood appellate review.

Four U.S. patents: US9264875B2, US10334397B2, US10321267B2, and US9357352B1 — all covering location-based social network discovery and interaction tracking systems.
The court issued a per curiam affirmance, indicating the lower court’s ruling was upheld on all challenged grounds. The appeal was ultimately dismissed without a detailed published opinion.
It reinforces the difficulty NPEs face in sustaining multi-patent infringement assertions against mobile platforms when claim construction and invalidity defenses are well-developed at the district level.
