Well, I dont know if this is old news or not, since it seems to have been brewing for a while.. But apparently Ultra is suing every Modular PSU maker out there :P.. here's an exerpt from the article and the link:
" Ultra filed the suit in the United States District of Florida Orlando Division and named as defendants no less than 22 of the top power supply makers. Named in the suit as defendants are Antec, Inc., Channel Well Technology Co. Ltd., Channel Well Technology Co. U.S.A., Inc., Corsair Memory, Inc., Enhance Electronics Co. Ltd., E-Power Technology/PCMCIS, SPI Electronic Co. Ltd., FSP Group USA Corp., Koolance USA, Mushkin, Inc., OCZ Technology, Sea Sonic Electronics Co. Ltd., Silverstone Technology, Inc., Spire-Bytecom Fanner Corporation, Tagan Technology Co. Ltd., Tagan Technology Co., Thermaltake Technology Co. Ltd., Thermaltake, Inc., Topower Computer Industrial Co. Ltd., Topower Computer U.S.A., Inc., Zalman Technology Company Ltd. and Zalman USA, Inc.
Unlike most other patent infringement lawsuits, Ultra Products is not seeking an injunction against the 22 other companies. Ultra argues that since the other manufacturers were informed in 2006 and early 2007 (shortly after the patent was granted) they willfully infringed on Ultra's intellectual property. Thus, Ultra is seeking up to triple damages against the power supply manufacturers -- the maximum allowed by law. "
