The U.S. International Trade Commission has said it will investigate and examine certain graphics systems, their components, and digital television transmission devices and their components manufactured by Taiwan’s Realtek and Hong Kong’s TCL Industries Holdings (and its subsidiaries). The products listed in the documents that have raised patent infringement issues are shipped in the United States, so the case falls under the jurisdiction of USITC.
AMD and ATI filed a complaint on May 5, 2022. It requires companies to ban the sale of products in the production of which their intellectual property might be used. In particular, in their complaint, the companies allege that the defendants in the case infringed five patents related to various graphics technologies.
ATI’s patents related to texture unpacking technologies, graphic architectures with unified shaders, and multi-threaded graphic processor systems were called into question. As for AMD, we are talking regarding patents related to the methods and implementation of the transfer and synchronization of data and events, as well as to the processor unit, which is responsible for asynchronous task scheduling.
The USITC commission will begin its investigation on July 1. It can take up to 45 days, following which the department will announce its decision.
