Securing $240 million and a jury verdict of willful infringement for Promptu in patent case against Comcast

Finnegan obtained a $240 million jury verdict for client Promptu in a patent infringement lawsuit against Comcast in the U.S. District Court for the Eastern District of Pennsylvania. The jury found that Comcast infringed Promptu’s patents covering voice recognition technology for TV and further determined that the infringement was willful.

Promptu filed suit alleging that Comcast’s voice enabled television products infringed Promptu’s voice recognition patents. After an adverse claim construction ruling led to stipulated non infringement to permit appeal, Finnegan successfully appealed to the U.S. Court of Appeals for the Federal Circuit. The Federal Circuit vacated an earlier judgment and remanded the case after concluding that the district court had construed key claim terms too narrowly. The remand cleared the way for Promptu to present its infringement case to a jury, which resulted in a $240 million verdict.

After nearly a decade of litigation, this verdict vindicates Promptu’s pioneering work in voice powered TV interfaces and confirms that Comcast’s products incorporated Promptu’s patented innovations.

Finnegan’s representation of Promptu has also included earlier victories at the Patent Trial and Appeal Board (PTAB), where Comcast’s inter partes review (IPR) challenges failed, confirming the strength of Promptu’s patent portfolio.
