Among the patent assignments recorded during the first week of November were multiple transfers from Intellectual Ventures LLC (IV)—two to affiliates of IP Valuation Partners LLC (d/b/a IPVal) (which currently has multiple ongoing campaigns asserting former IV patents), and one to a new NPE with an apparent connection to Cotman IP. The week also saw the recording of transactions between IQ Holdings, LLC and IPVal; Panasonic and PanOptis Equity Holdings LLC; and Microsoft and General Patent Corporation.

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.

In the first half of December 2015, RPX saw 14 patent transfers to NPEs recorded with the USPTO. A number of those transactions involved patents that have recently been asserted in litigation against operating companies.
