Commission Finds No Violation In Investigation 337-TA-666

On July 19, the Commission issued the public version of its opinion affirming on modified grounds ALJ Gildea's finding that no violation of section 337 occurred in Inv. No. 337-TA-666, Certain Cold Cathode Fluorescent Lamp Inverter Circuits and Products Containing the Same. ALJ Gildea's initial finding, released on April 19, 2010, found (1) that complainant O2 Micro had not satisfied the technical prong of the domestic industry requirement, (2) that none of the products manufactured by respondents Monolithic Power Systems, ASUSTeK Computer and Asus Computer International infringed U.S. Patent No. 7,417,382, (3) that respondent Microsemi's LX1691 and LX1693 products did infringe the '382 patent, and (4) that the '382 patent was valid and enforceable.

After deciding to review ALJ Gildea's initial determination, the Commission reversed the ALJ's finding that the complainants did not satisfy the domestic industry requirement.  However, the Commission also reversed ALJ Gildea's finding that the LX1691 and LX1693 products of respondent Microsemi Corporation infringed the patent at issue, and left undisturbed his rulings as to the remaining respondents, finding that no Section 337 violation had occurred.
