Yesterday Entropic Communications, a designer and maker of semiconductors and “system-on-a-chip” (SoC) technology, filed a patent infringement action against fellow SoC maker ViXS Systems in district court in the Southern District of California.  Entropic alleges that ViXS infringes two patents that are essential to the home entertainment networking standards developed and promulgated by the Multimedia Over Coax Alliance, also known as the MoCA family of standards or MoCa specifications (MoCA is a trade group, not a recognized SSO or SDO, so some do not like to refer to the MoCA specifications as “standards”).  The MoCA specifications have been widely adopted and are marketed as “the universal standards for home entertainment networking,” allowing users to stream high-definition content at high speeds throughout a house using their existing coax network (e.g., for use in multi-room DVRs, gaming, etc.).
