Three April 2020 assignments from operating companies to NPEs were recently recorded with the USPTO—two from Xerox and subsidiary Palo Alto Research Corporation (PARC) to an IP Edge LLC affiliate, comprising over 130 US assets; and one from Huawei to an NPE with ties to EVS Codec Technologies, LLC, whose codec campaign asserting former VoiceAge patents remains active.

Yet another set of patents originating with VoiceAge Corporation has now been asserted in NPE litigation, this time in partnership with Fortress Investment Group LLC. In December 2018, VoiceAge announced a “strategic transaction” with Fortress under which the investment firm would license VoiceAge’s portfolio related to the Enhanced Voice Services (EVS) wideband audio codec—with that portfolio assigned to Fortress “affiliate” VoiceAge EVS, LLC. That entity has now asserted five of those patents in litigation, accusing HMD Global (1:19-cv-01945) of infringement through the provision of Nokia-branded smartphones supporting EVS and alleging that the patents-in-suit are essential to that standard. VoiceAge has stated that its transaction with Fortress is designed to “advance . . . [VoiceAge’s] strategic objective of diversifying revenues from [its] IP assets”. This deal follows another partnership between VoiceAge and publicly traded Acacia Research Corporation that appears to have started in 2014, leading to the launch of a litigation campaign that year through Acacia subsidiary Saint Lawrence Communications LLC. That campaign remains active after being revived in August 2018 by licensee EVS Codec Technologies, LLC, with Saint Lawrence later dragged back into the campaign over a standing dispute.

Recently formed Texas NPE EVS Codec Technologies, LLC has kept a portfolio of wideband audio patents in litigation, filing suit against Huawei (2:18-cv-00346), LG Electronics (LGE) (2:18-cv-00343), and ZTE (2:18-cv-00344) on nearly the same day that saw the last case in a prior campaign closed. The defendants are accused of infringement through the provision of mobile devices supporting the Enhanced Voice Services (EVS) codec via Ultra HD Voice compatibility. LGE and ZTE were both defendants in the prior campaign as to devices supporting a predecessor of Ultra HD Voice/EVS (the AMR-WB, or HD Voice, codec) waged by Saint Lawrence Communications LLC, a subsidiary of publicly traded NPE Acacia Research Corporation. Acacia recently announced a significant shakeup in both its executive team and board of directors.
