TomTom launches countersuit against Microsoft

One of the top GPS manufacturers, TomTom has filed a patent infringement against Microsoft. The suit alleges that Microsoft is infringing on at least four patents held by TomTom by releasing the popular Microsoft Streets and Trips software program.

The complaint is launched in response to a lawsuit filed by Microsoft against TomTom last month. Their complaint alleges that TomTom infringed on eight of their patents by using Microsoft’s file allocation table technology.

Despite the new complaints launched by TomTom, Microsoft is not expected to withdraw their original lawsuit. In a statement issued yesterday by Microsoft, the company has said, “We are reviewing TomTom’s filing, which we have just received. As has been the case for more than a year, we remain committed to a licensing solution, although we will continue to press ahead with the complaints we initiated in the U.S. District Court for the Western District of Washington and the International Trade Commission.”
