Cox sues Sprint unit over alleged patent infringement

Cox Communications Inc. sued a Sprint Nextel Corp. unit in Delaware federal court, seeking a ruling that it doesn’t infringe 12 Sprint telecommunications patents and that the patents aren’t valid.

Cox, based in Atlanta, also contends Sprint Communications Co. is infringing two of its patents for data management, according to a complaint filed in Wilmington.

“There is a substantial controversy between the parties of sufficient immediacy and reality,” and “the Cox entities do not infringe any valid and enforceable claim of the Sprint patents,” Cox lawyers said in court papers.

The Delaware lawsuit stems from a related complaint filed by Overland Park, Kansas-based Sprint in December in Kansas City, alleging Cox infringes the 12 patents.

Scott Sloat, a spokesman for Overland Park-based Sprint Nextel spokesman, didn’t immediately return voice and e-mail messages seeking comment on the lawsuit.

Cox provides video, high-speed Internet and telephone services. Sprint provides wireless, wireline and Internet access, among other services.
