RPX took note of seven patent transfers to NPEs recorded during the first half of September 2016. Assignees included Mobile Synergy Solutions, LLC (which has ties to Monument Patent Holdings, LLC and Dominion Harbor Group, LLC); Silkeen LLC (a newly formed NPE apparently connected to IP Edge LLC); and Blackbird Tech LLC. NPEs controlled by Monument Patent Holdings or IP Edge have collectively filed over 280 patent infringement cases so far this year, and Blackbird Tech, which has waged 11 litigation campaigns to date, has filed 30 cases in 2016.

In the first half of May 2016, RPX saw nine patent transfers to NPEs recorded with the USPTO. At least three of those transactions involved patents that have already been asserted in litigation against operating companies.

For the first half of April, RPX saw 20 transfers of patents recorded with the USPTO.
