AMD Files Patent Infringement Complaint Against 4 Companies

AMD Files Patent Infringement Complaint Against 4 Companies

AMD believes several companies copied their designs for processors. They filed patent infringement complaints against LG, MediaTek, Vizio, and Sigma Designs. The patents covered contemporary graphics processing including:

  • Unified shaders (‘133)
  • Parallel pipeline graphics system (‘506)
  • Graphics processing architecture employing unified shaders (‘454)
  • GPU architectures with unified shaders (‘967)

One of the products suspected of violating these patents is MediaTek’s Helio P10 SoC. This chip is used in smartphones designed by LG. It features the Mali T860MP2 GPU licensed from ARM (a third party developer). The SX7 (STV7701) SoC from Sigma is also named in the complaint. It is used in Vizio’s UHD TVs with HDR support. This chip features a quad-cluster GPU developed by ARM.

The LG 49UH6500 and Vizio’s E43U-D2 are two more examples of infringement cited by AMD. AMD is also accusing these products of damaging legitimate licensees of AMD’s IP.

AMD announced plans in 2014 to monetize their IP portfolio. They signed a deal with Tianjin Haiguang Advanced Technology Investment Co., Ltd last year. They agreed to develop server SoCs. This could have been a motivating factor for filing the complaint now.

AMD has requested that the US ITC issue a limited exclusion order and a cease and desist order to prevent imports of the products into the United States.
