Power management and security components supplier O2Micro International Ltd. has filed a patent infringement lawsuit in the Eastern District of Texas against both Sony Corp. and Rohm Co. Ltd. of Japan for allegedly violating three patents related to certain Sony LCD TVs and other LCD products containing certain Rohm integrated circuits. The three patents asserted in the infringement suit are U.S. Patent Nos. 6,804,129, 6,501,234 and 6,707,264. O2Micro (Santa Clara, Calif.) will seek enhanced damages for willful infringement of its patented technology and injunctions against importation or sale of these products into the United States.

FYI: The US Patent mentioned here (US5453863) was used by Kent to cause the bankruptcy of ADS. Now, the EPO unanimously decided that its disclosure is insufficient to teach the invention – and that is after Kent's entire senior technical staff appeared to personally try to convince & explain to the EPO otherwise.

Cheers,

Abe
