Cox files suit against AT&T, city of Tempe, Ariz.

Cox Communications has filed a federal lawsuit against the city of Tempe, Ariz., alleging that the city's regulations favor Google Fiber.

"As set forth below, the city has violated federal law in a manner that directly harms Cox by establishing a discriminatory regulatory framework," said the complaint, which was obtained by the Atlanta Journal Constitution. "The city's regulatory framework imposes substantial statutory and regulatory obligations on providers of video services that the city deems to be cable operators (such as Cox). The city exempts from such rules and obligations providers of video services that the City deems not to be cable operators (such as Google Fiber). Legally, however, Google Fiber's proposed video offering is indistinguishable from Cox's cable service offering."

Cox is also suing AT&T for patent infringement, accusing the company's U-verse service of cribbing its technologies. Article
