ITC rules in favor of Finnegan clients

An administrative law judge with the U.S. International Trade Commission (ITC) found that cold cathode fluorescent light ("CCFL") inverter circuits produced by Finnegan client Monolithic Power Systems do not infringe a patent owned by complainant O2 Micro.  O2 Micro had previously withdrawn infringement allegations based on three other patents earlier in the case.  The ALJ also found that laptop computers and flat screen monitors incorporating the accused MPS chips sold by Finnegan clients ASUSTeK Computer and ASUS Computer International did not infringe the same patent.  Further, the ALJ found that O2 Micro's own products do not practice the patented technology and, as a result, there was no domestic industry, a necessary showing in an ITC case.  MPS and its customers were found to have not violated Section 337.
