In October 2003, LeapFrog filed a complaint in the federal district court of Delaware against Fisher-Price, alleging that the Fisher-Price PowerTouch toy violated LeapFrog's patent. The court returned a verdict in favour of the defendant, Fisher-Price.
Tom Kalinske, Leapfrog’s Chief Executive Officer, said: "We have, and always will, vigorously defend our patented technology. LeapFrog's proprietary technology allows us to create some of the most innovative educational products available, and these products provide both a highly engaging and an effective learning experience.
"Technology-based patent litigation is very complex and challenging. Nonetheless, we will continue to defend our intellectual property rights in the future."
