Empire IP LLC affiliate Environment Sensor Systems LLC has filed two new complaints in its four-month-old litigation campaign, targeting Link 4 (2:16-cv-00897) and Swarm Technologies (2:16-cv-00898), following two suits earlier this month, one against HisGadget (2:16-cv-00857) and the other against Home Depot and Soil IQ (2:16-cv-00848). Meanwhile, fellow Empire affiliate Network Architecture Innovations LLC has resumed its own campaign after a nine-month hiatus, filing complaints against 2169061 Ontario (d/b/a CamFuze) (2:16-cv-00913), CC Network (2:16-cv-00914), Shoshoro (2:16-cv-00915), Spider Media (2:16-cv-00917), Youngtek Solutions (2:16-cv-00916), WebPower (2:16-cv-00912). This round of suits is the NPE’s first since its last wave of filings in November 2015.

A second NPE affiliated with Empire IP LLC has launched its first litigation campaign in the past week. Newly formed NPE Environment Sensor Systems LLC filed a single complaint on May 5 against Hunter Industries and SiteOne Landscape Supply, as well as ten John Does (2:16-cv-00480). Environment Sensor Systems alleges infringement of a single patent (7,231,298) generally related to an environment detection device that uses sensors to measure multiple conditions to determine what vegetation is capable of “thriving” there. The accused products include smart irrigation systems that contain various types of environmental sensors. This new lawsuit comes just two days after fellow Empire IP affiliate Theft Prevention Innovations LLC started a campaign of its own, asserting two security systems patents against multiple defendants.

In the second half of March 2016, RPX saw twelve patent transfers to known NPEs recorded with the USPTO. Several of those transactions involved patents that have already been asserted in litigation against operating companies.
