Taiwan Semiconductor Manufacturing Company (TSMC) is countersuing rival semiconductor manufacturer GlobalFoundries, alleging several instances of patent infringement related to the company's 40-nanometer, 28-nanometer, 22-nanometer, 14-nanometer, and 12-nanometer process nodes. As part of the lawsuit, TSMC is seeking "substantial monetary damages."
Now this is turning into a tit-for-tat ordeal, with countersuits filed in the US, Germany, and Singapore. TSMC said it is "ready for battle in the courts." TSMC also said it "demands injunctions to stop GlobalFoundries' manufacture and sale of infringing semiconductor products."
GlobalFoundries has responded to the countersuits, saying it is not intimidated by the "retaliatory litigation."
"TSMC has long used its dominant market position to exert pressure on its smaller competitors, and the retaliatory litigation filed today is in keeping with that history. We have confidence in our position and the legal process, and we are not intimidated by these actions," said Sam Azar, a GlobalFoundries executive.
