SAN FRANCISCO, Jan. 4, 2016 /PRNewswire/ -- RPX Corporation (NASDAQ: RPXC), the leading provider of patent risk management solutions, today released its 2015 NPE Activity: Highlights report—a first look at trends in patent litigation activity for 2015. Among the key findings are:

• NPE litigation activity rebounded in 2015 following what now appears to have been a slowdown in the latter half of 2014.
• The Eastern District of Texas continues to dominate as the venue of choice for NPEs. NPEs sued more defendants there in 2015 than in any year since 2009.
• Inter partes reviews (IPRs) and covered business method (CBM) petitions filed with the Patent Trial and Appeal Board (PTAB) that have reached final decision on patent validity have been, on average, successful. However, data also show that the PTAB's institution rates (allowing petitions to proceed to trial) were on the decline in 2014 and 2015.

The full report includes information and insight on NPE litigation volume, top plaintiffs and most targeted defendants, patent validity challenges (IPRs and CBMs), and the size of patent portfolios offered for sale.

The 2015 NPE Activity: Highlights report is available here.  

RPX will publish its annual series of full, detailed reports on NPE litigation, the NPE marketplace, and cost of NPE litigation over the next several months. Access previous editions at www.rpxcorp.com/reports.
