(Nasdaq: AAOI), a leading provider of fiber-optic access network products for the cable broadband, internet datacenter, telecom and fiber-to-the-home (FTTH) markets, today announced that it has amended its previously filed complaint for patent infringement, Case No.: 3:23-cv-04787.

“Patents are extremely important to AOI’s optical transceiver business. Therefore, AOI is taking, and will continue to take the steps necessary to protect its intellectual property, including enforcing its patents against all alleged infringers,” said Dr. Thompson Lin, Applied Optoelectronics Inc. Founder, President and Chief Executive Officer.

AOI is a leading provider of fiber-optic access network products for the cable broadband, internet datacenter, telecom and fiber-to-the-home (FTTH) markets and has invested significantly in the development of its technology and in building its IP portfolio.

In the amended complaint, AOI is seeking monetary damages and a permanent injunction.
