TAIPEI -- Taiwan Semiconductor Manufacturing Co. has launched retaliatory legal action against struggling U.S.-based rival Globalfoundries as it moves to protect its position as the world's largest contract chipmaker.
TSMC, which controls around 50% of the global chip market supplying over 460 developers including Apple, Huawei Technologies and Google, accused Globalfoundries of patent infringement in the U.S., Germany, and Singapore, demanding compensation and a ban on further product sales.
