Comcast IP Holdings I LLC v. Sprint Communications Co., No. 15-1992 (Fed. Cir. 2017)Annotate this Case
Comcast sued Sprint for infringement of the Low Patents, which are in the same patent family and are generally directed to methods of using Domain Name System (DNS) technology, such as the Internet, to initiate and route a phone call through a switched telecommunication system. A jury found that Sprint’s handling of certain phone calls infringed various claims and awarded Comcast a $7.5 million damages award. The district court denied Sprint’s motion for judgment as a matter of law or for a new trial, and added prejudgment interest to the damages award. The Federal Circuit affirmed, upholding findings that “[a] system with elements of both switches and a ‘datagram-based system’ is not necessarily outside the scope of a ‘switched telecommunication system.’”; “A ‘communication system’ is still a broader concept than a ‘switched telecommunication system’ even where the ‘switched telecommunication system’ has elements of a ‘datagram-based system,’ because a ‘switched telecommunication system’ at a minimum must have switches and function on a bearer network”; and that “parsing” was an automated process because it necessarily required a computer.
