Interdigital Communications LLC et al v. Nokia Corporation et al DC

The Patent Trial and Appeal Board (PTAB) saw activity in a variety of notable campaigns throughout February 2018, with petitions for inter partes review (IPR) filed against publicly traded Quarterhill Inc. as well as Fundamental Innovation Systems International LLC, Intellectual Ventures LLC, Realtime Data LLC, and Uniloc Corporation Pty. Limited. The Board also instituted trial in February for IPRs against General Patent Corporation, Oyster Optics, LLC, and Uniloc. In addition, the PTAB issued final decisions throughout February in IPRs against a range of different patent owners, including publicly traded NPEs (Acacia Research Corporation; InterDigital, Inc.; and VirnetX Inc.), an individual inventor (Daniel L. Flamm), and privately held plaintiffs (ChanBond, LLC; Makor Issues & Rights Ltd.; Papst Licensing GmbH & Company Kg; and Personalized Media Communications, LLC).

The Federal Circuit has affirmed a Delaware jury’s October 2014 infringement verdict for InterDigital, Inc. in the NPE’s case against ZTE (1:13-cv-00009). In a decision issued on November 3, the court upheld District Judge Richard G. Andrews’s post-trial ruling that the jury’s finding of infringement as to three wireless communications patents had been properly supported by the evidence, also affirming Judge Andrews’s construction of a key claim term (2016-2362). That verdict issued in the first of two trials in the same lawsuit, the second of which culminated in a finding of noninfringement for ZTE as to a fourth patent in April 2015.
