Last week, RPX reported that Rampart Asset Management LLC—formed in Texas by Peter J. Hardigan—had expanded its memory controller campaign with a case against TI, preceded by 2021 suits against each of NXP Semiconductors and Renesas Electronics. The asserted patents are a small subset of the more than 80 US patents assets that Rambus Inc. assigned to another entity, apparently also under Hardigan’s control, in August of last year.

In the first half of August 2016, RPX saw five patent transfers to NPEs recorded with the USPTO. Assignees include IP Valuation Partners LLC—affiliates of which have collectively filed nearly 50 patent infringement suits to date—and France Brevets. Also, a newly formed NPE controlled by the manager of Multiplayer Network Innovations, LLC, which in 2014-2015 sued over 25 operating companies, received a patent from Rovi Corporation.

In the second half of April 2015, RPX saw 13 transfers of patents recorded with the USPTO.

September 27, 2012 – Rambus announced that it has entered into a six year patent license agreement with Fujitsu Semiconductor Limited for patented technology included in Fujitsu’s integrated circuit products.
