On Monday, Globalfoundries (GF), a chip maker based in Santa Clara, California, said it filed patent infringement claims in the US and Germany against 20 companies that use processors from rival Taiwan Semiconductor Manufacturing Company (TSMC).

"For years, while we have been devoting billions of dollars to domestic research and development, TSMC has been unlawfully reaping the benefits of our investments," said Gregg Bartlett, senior vice president, engineering and technology at GF in a statement. "This action is critical to halt Taiwan Semiconductor’s unlawful use of our vital assets and to safeguard the American and European manufacturing base."
