GlobalFoundries Initiates Patent Infringement Lawsuits Against Tower Semiconductor

On March 26, 2026, GlobalFoundries, a prominent American semiconductor manufacturer, filed multiple lawsuits against Israel-based Tower Semiconductor, alleging infringement of 11 patents related to chip manufacturing technologies. The lawsuits were submitted to the U.S. District Court for the Western District of Texas and the U.S. International Trade Commission (ITC). GlobalFoundries aims to block the importation of chips produced by Tower Semiconductor that allegedly utilize its patented technologies without authorization.

GlobalFoundries and Tower Semiconductor operate within the specialty chip manufacturing sector, focusing on niche markets such as radio-frequency chips and silicon photonics. This sector contrasts with larger manufacturers like Taiwan Semiconductor Manufacturing Co. and Intel, which concentrate on high-performance computing chips. GlobalFoundries has committed to significant investments in its facilities, announcing a $16 billion expansion plan aimed at enhancing its research and development capabilities.
