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.

Saint Lawrence Communications LLC has filed suit against Amazon (2:19-cv-00027), asserting a familiar set of five data compression patents in a new complaint that targets a long list of devices supporting the Adaptive Multi-Rate-Wideband (AMR-WB) audio codec for speech. The accused products include the Fire Phone, various Fire TV products, various Kindle Android tablets, and various Echo and Alexa products (including those running Amazon’s Android-based Fire OS). Saint Lawrence, a subsidiary of Acacia Research Corporation, pleads ownership of the patents asserted; last August, EVS Codec Technologies, LLC—claiming the exclusive right to grant licenses covering products practicing the Enhanced Voice Standard (EVS) for voice services over LTE/4G networks—asserted the same five patents in suits filed against Huawei, LG Electronics (LGE), and ZTE. The Saint Lawrence Communications complaint acknowledges a “prior settlement and license agreement” with Amazon but further alleges that “Amazon is not currently licensed to the patents asserted in this Complaint with respect to the activities accused of infringement”.

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.
