Dainippon Screen Mfg. Co. Ltd. v. CFMT, Inc., et al.

This declaratory relief action requested a judgment of noninfringement and invalidity. We successfully appealed a jurisdiction dismissal (142 F.3d 1266))(reversing dismissal for lack of personal jurisdiction and giving opponent a “Chutzpah Award”). After remand, the patentee counterclaimed on four patents involving semiconductor cleaning and drying technology used in state-of-the-art semiconductor fabrication equipment. We presented claim construction arguments at several Markman hearings. Following a month-long jury trial, this case was successfully settled.
