Comcast Sues Sprint Over Four Telecommunications Patents

February 27, 2012

(Updates with excerpt from complaint in second paragraph.)

Feb. 23 (Bloomberg) -- Comcast Corp., the largest U.S. cable company, sued a unit of Sprint Nextel Corp. over four telecommunications patents.

Comcast “has been irreparably harmed by that infringement and will suffer additional damages,” unless the court prevents additional infringement, lawyers for the company said in a complaint filed Feb. 21 in Delaware federal court.

Scott M. Sloat, a spokesman for Overland Park, Kansas-based Sprint, said the company couldn’t immediately comment on the lawsuit.

Comcast contends that services provided by Sprint, the nation’s third-largest wireless phone company, misappropriate technology used for accessing communication data, determining a telephone number and optimizing a telephony network.

Comcast last week filed a separate suit against Sprint claiming infringement of four other telecommunication patents in federal court in Philadelphia. Sprint sued Philadelphia-based Comcast and three other cable companies in December alleging infringement of patents related to transmitting phone calls over digital lines.

The case is Comcast v. Sprint, 12-cv-00205, U.S. District Court, District of Delaware (Wilmington).
