Cox Communications Inc. sued a Sprint Nextel Corp. (S) 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 yesterday 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 said in court papers.
“We aren’t commenting on this case,” Stephanie Vinge- Walsh, a Sprint spokeswoman, said in an e-mailed statement.
Cox provides video, high-speed Internet and telephone services. Sprint provides wireless, wireline and Internet access, among other services.
The case is Cox Communications v. Sprint Communications, 12cv487 U.S. District Court, District of Delaware (Wilmington).
