PALTALK HOLDINGS VS. MICROSOFT

By Chris Bennett, Tudor Carsten, Michael R. Coburn, Sarah Dale-Harris, Pablo Guzman, Danielle (Dani) Lemon, Chris Metcalfe and David Spratley

PalTalk Holdings has instituted legal proceedings against Microsoft on the basis that Microsoft's Halo and Xbox infringe its patents related to "controlling interactive applications over multiple computers".

Microsoft is challenging the validity of the patents and PalTalk's claim that the patents are worth $90 million.

These patents were originally registered by MPath Interactive who had many meetings with Microsoft regarding this technology.

The Washington State Patent Law Blog reports that Microsoft's motion for a partial summary judgment has been denied on the basis that Microsoft "has not met its burden of showing that the two patents were anticipated by clear and convincing evidence".
