Virginia Innovation Sciences, Inc. (VIS) has filed a second case against Amazon (2:17-cv-00422), asserting two patents already at issue in a separate, July 2016 suit against the defendant, as well as two patents newly asserted in the campaign, one of which issued on the date the complaint was filed, August 8. That same day, VIS filed yet another case against HTC (3:17-cv-00560), asserting two patents not among the multiple, related patents already at issue between the two defendants. In January 2017, those patents, also asserted against Amazon, were invalided under Alice, as patent-ineligibly drawn to the abstract idea of “converting a video signal for a mobile terminal to an ‘alternate display terminal’”. VIS has appealed that ruling to the Federal Circuit (2017-1482), as litigation before the district court continues.
