Jury bans Ultra Clean gas delivery system

December 3, 2007 – A jury has ruled for a permanent injunction against Ultra Clean manufacturing, selling, or importing its Predator gas delivery systems or “colorably similar” products into the US, and must pay rival Celerity royalties for past infringing sales plus interest as well as legal costs.

The ruling follows two-year litigation between Celerity and Ultra Clean, initially over eight patents but earlier this year reduced to one (finding two Celerity patents valid, but only one infringed upon, regarding modular gas delivery technology).

The ruling “validates Celerity’s strategy to invest in developing advanced modular substrate technology supporting our customer’s next generation semiconductor manufacturing solutions,” said David Somo, SVP of sales and marketing at Celerity, in a statement.

Ultra Clean noted that its payments amount to $13.9K in royalty damages (plus
$523.91 in pre-judgement interest), and the overall judgement plus legal costs “is not expected to have a material adverse effect on UCT’s operating results or financial condition.”
