DoggyPhone LLC v. Tomofun LLC, decided 21 Nov 24

The case is about DoggyPhone's patent infringement lawsuit against Tomofun. The lower court granted summary judgment to Tomofun, finding its "Furbo" device did not infringe DoggyPhone's patent for a remote pet communication system. The appellate court affirmed, focusing on the key claim limitation requiring transmission initiation in response to pet input. The court held that the Furbo's user-initiated transmission, triggered by a notification, did not satisfy this limitation, thus supporting the non-infringement ruling. The court did not need to address the other two grounds for summary judgment.
