Recent SEC filings suggest ever shakier financial ground for Quest Patent Research Corporation (QPRC), as the publicly traded NPE approaches trial in one of its open campaigns, litigated by subsidiary Semcon IP Inc.; revives a second campaign, litigated by subsidiary Mariner IC Inc.; and discloses the acquisition of yet another group of patents from Intellectual Ventures LLC (IV) by a third subsidiary, CXT Systems, Inc. The new defendants targeted by Mariner IC are Acer (2:18-cv-00068), ASUS (2:18-cv-00069), Bose (2:18-cv-00067), Schneider Electronics (2:18-cv-00070), and Sharp (2:18-cv-00071). The patents asserted generally relate to anchoring a semiconductor die to prevent cracking, with the accused products across the campaign being chips made from certain semiconductor dies, as well as products that contain such chips. Meanwhile, Semcon IP faces jury selection on April 2 in the Eastern District of Texas in cases filed against MediaTek, STMicro, and ZTE over separate patents, also acquired from IV.
