Microsoft strikes back at Lucent - News at GameSpot

"A long-simmering dispute over technology used in Microsoft's Xbox 360 game console has heated up. Defendant Microsoft, sued by Lucent Technologies in March for infringing on patents it owns, has filed a countersuit denying the Lucent claims and brings a few charges of its own.

In documents filed Monday in a US District Court in San Diego, not only did the console maker deny infringing on a 1993 Lucent patent which concerns MPEG-2 video encoding (Patent No. 5,227,878, titled "Adaptive Coding and Decoding of Frames and Fields of Video"), it argued that the initial claim of Lucent is invalid, reportedly due to Lucent's failure to disclose prior art when making its initial application with the US Patent and Trade Office.

Monday's counterclaim also accuses Lucent of infringing on a number of Microsoft-owned patents."
