December 3, 2007 — /PRNewswire/ — MILPITAS, CA — Celerity, Inc., a technology leader in precision instruments and advanced gas and liquid delivery solutions for the global semiconductor and electronics industries, announced today the U.S. District Court for the Northern District of California issued a permanent injunction in Celerity’s patent infringement suit against Ultra Clean Holdings, Inc., and its subsidiary Ultra Clean Technology Systems and Service, Inc., Menlo Park, CA (“UCT”). The court’s order prohibits UCT from manufacturing, selling, and importing any Predator or “colorably similar” products into the United States.

In June, a unanimous jury validated Celerity’s U.S. Patent Nos. 6,435,215 and 6,394,138, and found that UCT’s Predator product infringed on Celerity’s patented modular gas delivery technology used in semiconductor manufacturing and other related industries requiring high-precision process control.

In addition to the permanent injunction, the court ordered that UCT pay Celerity royalties for past infringing sales by the Predator product, plus interest, as well as for costs incurred while prosecuting this action.

“This is a landmark victory for us as it validates Celerity’s strategy to invest in developing advanced modular substrate technology supporting our customer’s next generation semiconductor manufacturing solutions,” says David Somo, senior vice president of sales and marketing at Celerity.
