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.
