On January 24, 2017, AMD filed a complaint against several prominent tech companies, requesting that the ITC commence an investigation pursuant to Section 337. The basis for the complaint: some of these companies (namely, LG, MediaTek, VIZIO, and Sigma) unlawfully import into or sell inside the U.S. products which infringe on AMD's graphics intelectual property - namely, on U.S. Patent Nos. 7,633,506 (the '506 patent), 7,796,133 (the '133 patent) and 8,760,454 (the '454 patent) (collectively, the "asserted patents".
According to the complaint, these patents generally relate to architectures for graphics processing unit (GPU) circuitry. The '506 patent relates to "a graphics processing architecture that enables a large amount of graphics data to be rendered to a frame buffer". The '133 patent relates to specialized "texture" processing circuitry that is employed by GPUs. Lastly, the '454 patent relates to a "unified shader" hardware architecture for GPUs. The complaint specifically refers to various televisions and smartphones, specifically, towards the graphics processing systems within those televisions and smartphones - as infringing products.
