Global Technology filed patent infringement lawsuits against CreaLights

Applied Optoelectronics announced that its subsidiary Global Technology has filed two lawsuits for patent infringement against Suzhou CreaLights Optoelectronics Technology in China. The two complaints, filed on December 8, 2023 in the Suzhou Intermediate People’s Court of the People’s Republic of China, allege that at least the CreaLights 100G QSFP28 CWDM4 optical transceiver module infringes AOI’s Chinese patent No. ZL201780050835.X, entitled “Optical transceiver with a multiplexing device positioned off-center within a transceiver housing to reduce fiber bending loss”, which was filed on August 18, 2017, and the CreaLights 100G QSFP28 CWDM4 and 100G QSFP28 PSM4 optical transceiver modules infringe Global Technology’s Chinese patent No. ZL201720846636.7, entitled “High speed optical transceiver module”, which was filed on July 13, 2017. “We believe that CreaLights is infringing two of our key optical transceiver patents. As a company promoting innovation, AOI understands the critical role of intellectual property, and we will vigorously defend our patents. Therefore, we have filed this lawsuit as a step to protect our intellectual property,” said David Kuo, Senior VP & Chief Legal Officer.
