The Patent Trial and Appeal Board (PTAB) saw the number of petitions for AIA review in November hold fairly steady at 111 (compared to October’s 128) as the US Supreme Court continued its review of the constitutionality of inter partes review (IPR) in Oil States v. Greene’s Energy Services, for which oral arguments were held on November 27. Among the NPEs targeted by petitions brought in November were publicly traded Quarterhill Inc. and Xperi Corporation, prolific litigant Brian Yates, and several privately held NPEs waging networking campaigns, including Alacritech, Inc.; Iridescent Networks, Inc.; Monument Patent Holdings, LLC; MyMail Ltd.; and Oyster Optics LLC. The PTAB also instituted trial in November for other IPRs against Alacritech and Quarterhill and for an IPR against Plectrum LLC. Final decisions issued by the Board in November include one in the automotive campaign waged by Paice LLC and in IPRs against InfoGation Corporation and VoIP-Pal.com, Inc., both of which saw their patents survive review.

The Patent Trial and Appeal Board (PTAB) continued to see petitions for AIA review filed against prolific litigants in July, including a wave of petitions against Uniloc Corporation Pty. Limited across four separate campaigns, with petitions also brought against General Patent Corporation, Intellectual Ventures LLC (IV), Papst Licensing GmbH & Company Kg, and Quarterhill Inc. Meanwhile, throughout July, the Board instituted trial for inter partes reviews (IPRs) filed in semiconductor campaigns waged by Harvard University and the California Institute of Technology, with trial also instituted in campaigns related to network data compression (Realtime Data LLC), servers and data management (IV), and anti-malware technology (Finjan Holdings, Inc.). Final decisions issued by the Board in July included one that cancelled claims from a patent that has been asserted by Rothschild Connected Devices Innovations, LLC, an NPE controlled by inventor Leigh M. Rothschild, against more than 60 defendants.

The Patent Trial and Appeal Board (PTAB) saw 54 petitions for AIA review brought against NPEs in May, up from 20 such petitions filed in April. May PTAB filings included a resurgence in petitions against publicly traded NPEs, including Acacia Research Corporation; Pendrell Corporation; Quest Patent Research Corporation; VoIP-Pal.com, Inc.; Xperi Corporation (f/k/a Tessera Holding Corporation); and Wi-LAN Inc. (WiLAN) (which was renamed to Quarterhill Inc. on June 1). A variety of private litigants were also hit by PTAB petitions in May, including Blackbird Tech LLC, Global Equity Management (SA) Pty. Ltd., General Patent Corporation, Realtime Data LLC, and Uniloc Corporation Pty. Limited.

Alacritech, Inc., a company founded by SCSI creator and Adaptec founder Larry Boucher, has resumed its long-dormant litigation campaign with three suits against CenturyLink (2:16-cv-00693); Dell (2:16-cv-00695); and SMS InfoComm, Wistron, and Wiwynn (2:16-cv-00692). The defendants are accused of infringing a group of eight networking patents through various servers, data centers, and services related to network infrastructure. These lawsuits are Alacritech’s first since the company switched its business model to patent licensing and assertion in 2013, after ceasing production of a line of network interface cards (NICs).
