SANTA CLARA, Calif.: #25GPON--Cambridge Industries USA, Inc. (CIG USA), a Delaware corporation headquartered in Santa Clara, California, today announced that it has filed Petitions with the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office for Inter Partes Review (IPR) of U.S. patents asserted by Applied Optoelectronics, Inc. (AOI, NASDAQ:AAOI) in AOI’s infringement action, which is pending in the United States District Court for the Northern District of California.

The Petitions seek the cancellation of all claims in the patents as unpatentable, which, as demonstrated in CIG USA’s Inter Partes Review Petitions, are invalid due to anticipation or obviousness. Decisions on whether to institute the IPRs are expected by mid-2025, well in advance of the scheduled District Court trial date in June 2026.

CIG USA remains firmly committed to upholding fairness, integrity, and the true purpose of intellectual property rights—to foster innovation and protect legitimate contributions, not to obstruct healthy competition.
