Motorola Mobility has filed a patent lawsuit against Apple in a Florida federal court. The phone maker is accusing Apple of infringing on six patents related to messaging, antennas, software and data filtering with its mobile devices, Reuters said. Motorola also argued that Apple’s iPhone 4S specifically infringes on one of its patents. Just two weeks ago, the International Trade Commission (ITC) ruled that Motorola’s handsets did not infringe three Apple patents. The Mannheim Regional Court in Germany also ruled to ban sales of various iPhone and iPad models in December, although Apple has been given the opportunity to remove the infringing technology from its devices to avoid a ban in the country.
