In the suit, VIZIO, a U.S. company based in Irvine, California, alleges that Funai, acting alone and in concert with others, infringes numerous VIZIO patents in its manufacturing, importation and distribution of high definition televisions.  Funai manufactures and distributes high definition televisions for declining market share brand names, including Philips, Magnavox, Emerson, Sylvania, and Symphonic.
VIZIO is seeking an injunction prohibiting Funai from importing and selling infringing high definition televisions and is also seeking award of damages for millions of past infringing sales.

Previously, Funai sued VIZIO for patent infringement, resulting in a controversial and long-running court battle between the two companies that has not been entirely resolved. Subsequently, Vizio sued Funai for antitrust and unfair competition, because they thought that Funai had inappropriately acquired the rights to one US patent in particular, and had then “unfairly discriminated against VIZIO in the licensing and enforcements” of the patent.
