GlobalFoundries sues TSMC for patent infringement, seeks ban on certain products

U.S.-based chipmaker GlobalFoundries Inc. sued its larger rival Taiwan Semiconductor Manufacturing Co. Ltd. for patent infringement.

GlobalFoundries claims that chip manufacturing technologies used by TSMC infringed 16 of its patents. The company is pursuing an order to stop the import of products containing chips produced with the infringing technologies into the U.S. and Germany. GlobalFoundries did not specify the products affected by the alleged infringement but listed QUALCOMM Inc., Google LLC, Apple Inc., NVIDIA Corp. and Lenovo Group Ltd. among TSMC's affected customers.

The company is also seeking "significant" damages from TSMC based on the Taiwanese company's alleged unlawful use of its technology.

For its part, TSMC called the allegations baseless and said it would "fight vigorously, using any and all options" to protect its proprietary technologies.
