Z4 files second MS lawsuit
Having only yesterday won $140 million in damages from Microsoft, Z4 Technologies has today renewed its legal assault, filing another lawsuit. The second suit is an extension of the first, charging that the same product activation patents found to be violated earlier were also broken in the creation of Office and Windows Vista. Microsoft insists that it has done nothing wrong, and is now reviewing the case; the company's odds may not be good however, as legal precedent is already on Z4's side.
