Multiple Delaware NPEs under the same apparent control have each taken over the litigation of patents—earlier passed to a Texas entity for assertion—after the patents have boomeranged back. Most recently, Circuit Ventures LLC assigned a family of circuit monitoring patents to Texas entity Wireless Monitoring Systems LLC, which asserted them in litigation from November 2016 to January 2019 before assigning the family back. Circuit Ventures has sued NXP Semiconductors (6:19-cv-00275) and Pepprl + Fuchs (4:19-cv-01515) in April 2019 and Honeywell (1:19-cv-00857), Link Interactive (1:19-cv-00856), and Scout Security (1:19-cv-00858) so far in May. Likewise, Universal Cipher LLC assigned a single patent generally related to “dynamic” text generation to Cumberland Systems, LLC, which asserted it in litigation from May 2017 to May 2018 before returning the patent to Universal Cipher, which has now sued Best Buy (2:19-cv-00160), Target (2:19-cv-00163), and Wal-Mart (2:19-cv-00164) over it. These reversals, as well as other assignment activity, suggest a return to Delaware for these and other NPEs affiliated with the same patent attorney, perhaps motivated by a recent Federal Circuit opinion clarifying that targets of letter-writing campaigns can seek declaratory judgments in their home districts, rather than risk being sued elsewhere.

Connext DDS Secure is the latest password management system, provided by Real-Time Innovations (RTI), to draw the attention of Cumberland Systems, LLC, which has filed four new lawsuits, one each against Cisco (6:18-cv-00112), Lockheed Martin (3:18-cv-00554), Raytheon (6:18-cv-00110), and Siemens (6:18-cv-00111) over their alleged use of the system.

Cumberland Systems, LLC has filed cases against four more customers based on their alleged use of a password management system provided by Keeper Security. The sole patent-in-suit generally relates to password encryption, and the defendants in this second round of suits in Cumberland Systems’s campaign are AT&T (AT&T Mobility) (6:17-cv-00570), Chipotle (6:17-cv-00569), JPMorgan Chase (6:17-cv-00571), and Texas Freight Services (6:17-cv-00572). The first round, filed in May, hit five other alleged customers of Keeper Security—Edmunds, Marriott, Sony, True Media, and Verizon; all nine of these companies are identified as Keeper Security customers on that provider’s website (and/or on websites that compare various software products). All five of the earlier cases were dismissed, some without prejudice, within a couple months of filing, as were cases against two alleged customers of Sookasa’s password management platform. The other three first-round defendants, all alleged LastPass users, were dismissed simultaneously on September 18.
