Entropic and other STBs hit by patent claim

DirecTV, Entropic, CyberTan and other set-top box suppliers have been named in a patent action by Canadian semiconductor company ViXS Systems and its US subsidiary, ViXS USA. ViXS is alleging that the technology companies are importing set-top boxes and other components that infringe four of its patents. The action seems to be a ‘tit for tat’ response to an action started by Entropic in May last year against ViXS.
The new complaint was filed April 17 with the US International Trade Commission. The full complaint states: “these companies have engaged in unfair trade practices by the importation, sale for importation, and sale after importation of certain set-top boxes (STBs), gateways, bridges, switches, and adapters and components thereof that infringe one or more claims of United States Patent Nos. 7,301,900 (the 900 patent), 7,099,951 (the 951 patent), 7,200,855 (the 855 patent), and 7,406,598 (the 598 patent) (collectively, the Asserted Patents).

The ITC complaint seeks to stop the importation into the US and sale after importation of a range of products, all of which include Entropic Multimedia over Coax (MoCA) chips or Entropic System-on-Chips (SoCs). For example, the ITC complaint lists several DirecTV STBs that include Entropic MoCA chips. In addition to the ITC action, ViXS will seek damages in US Federal Court through a separate filing.
