GEORGE TOWN, Grand Cayman, March 26, 2007 (PRIME NEWSWIRE) -- O2Micro(r) International Limited (NasdaqGS:OIIM - News) (HKSE:0457.HK - News), a leading supplier of innovative power management, and security components and systems, announced today that judgment has been entered and permanent injunction granted in its lawsuit against Beyond Innovation Technology Co., Ltd. (``BiTek''), SPI Electronic Co., Ltd., FSP Group, and Lien Chang Electronic Enterprise Co., Ltd. in the United States District Court in Marshall, Texas, following trial in May 2006.

In a memorandum and order entered on March 21, 2007, the Court entered judgment against the defendants for willfully inducing the infringement of asserted claims of U.S. Patent Nos. 6,259,615, 6,396,722 and 6,804,129. The court also granted a permanent injunction preventing defendants, their officers, agents, servants, employees, and attorneys, and those persons acting in active concert or participation with them who receive actual notice of the order by personal service or otherwise from manufacturing, using, selling, offering to sell or importing into the United States any inverter controllers or modules that infringe those claims including but not limited to inverter controllers having model numbers BIT3105, BIT3106, BIT3107, BIT3193 or belonging to those same families or any colorable imitation of the inverter modules and/or inverter controllers that infringe and from otherwise infringing or inducing others to infringe for the life of the aforesaid patents.


The defendants were further ordered to label prominently their respective inverter controller or module products covered by the order and their accompanying product literature ``Not for Sale in, Use in, or Importation into the United States.'' O2Micro expects that the defendants will file further post-trial motions with the Court challenging the judgment and injunction. The defendants may also appeal the case to the U.S. Court of Appeals for the Federal Circuit.
