Longtime Leadership at Acacia Steps Aside as Board Members Resign and New Texas NPE Asserts Saint Lawrence Sub’s Patents

August 8, 2018

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.
