The U.S. Court of Appeals for the Federal Circuit has reinstated a patent infringement lawsuit against Meta Platforms Inc., the parent company of Facebook and Instagram. The suit, filed by AlmondNet Inc. and its subsidiary Intent IQ LLC, alleges that Meta infringed on patents related to targeted advertising technologies.
The Federal Circuit’s decision, issued on September 3, 2025, found that the lower court had “implicitly construed” a critical claim term without providing AlmondNet the opportunity to challenge this interpretation. This procedural oversight led the appellate court to vacate the previous dismissal and remand the case for further proceedings. The court’s order is available here: Federal Circuit Order.
AlmondNet and Intent IQ specialize in developing technologies that enable advertisers to deliver targeted ads based on user behavior and preferences. They contend that Meta’s advertising platforms utilize methods covered by their patents without authorization. The reinstatement of this lawsuit underscores the ongoing legal challenges Meta faces concerning its advertising practices.
In response to the ruling, Meta stated that it respects the court’s decision and is prepared to defend its position as the case proceeds. The company emphasized its commitment to innovation and compliance with intellectual property laws.
This development adds to a series of legal battles Meta has encountered over its advertising technologies. In a separate case, the Federal Circuit upheld the invalidation of photo-tagging patents under 35 U.S.C. § 101, affirming that the claims were directed to abstract ideas without an inventive concept. Details of that decision can be found here: Federal Circuit Decision on Photo-Tagging Patents.
As the AlmondNet case returns to the lower court, the outcome could have significant implications for the digital advertising industry, particularly concerning the use and enforcement of patents in targeted advertising technologies.
