The Federal Circuit upheld that Tomofun's Furbo device does not infringe on DoggyPhone's patent as its notification system is user-initiated, not pet-initiated.
Judge Hughes highlighted the claim limitation requiring transmission to start based on pet input, stating that instead it begins based on user action.
The court emphasized the importance of the 'begins transmission' limitation, clarifying that the Furbo's structure does not satisfy the remote communication requirement.
This case underscores how precise language in patent claims can determine infringement outcomes, as a device's operational mechanics can dictate its legal status.
