SAN FRANCISCO, March 26 (Reuters) – GlobalFoundries on Thursday said it has sued Israel-based rival Tower ​Semiconductor, alleging that Tower Semiconductor infringed ‌on 11 GlobalFoundries patents that relate to manufacturing chips that go into smart phones and other electronic devices.

GlobalFoundries said it has filed ‌two ​complaints in the ⁠U.S. District Court for ⁠the Western District of Texas and one with the U.S. International Trade Commission (ITC). The Malta, New York-based semiconductor ​manufacturer said that the ITC case will seek to block the import ⁠into the U.S. of ⁠chips made by Tower Semiconductor ​that were made with technologies covered by ​the patents in the case.

Tower Semiconductor ‌did not immediately respond to a request for comment.

While large chip manufacturers such as Taiwan Semiconductor Manufacturing Co and Intel ⁠focus on making the fastest and smallest computing chips, GlobalFoundries and Tower Semiconductor are specialty ⁠chipmakers ‌that focus on niches such ⁠as radio-frequency chips and silicon ​photonics. ‌GlobalFoundries last year said it ​planned to ⁠spend $16 billion to expand its facilities in Vermont and New York, with a focus on research and development.
