RightQuestion LLC, an entity controlled by inventor Bjorn Markus Jakobsson, has launched a second litigation campaign with separate suits against AT&T (2:24-cv-00094) and Verizon (2:24-cv-00091) in the Eastern District of Texas. The plaintiff asserts three patents broadly directed to call authentication technologies, with the defendants accused of infringement through the provision of cellular networks that support the Call Protect service and STIR/SHAKEN protocols.

RavenWhite Licensing LLC has sued Home Depot (2:23-cv-00423) and Walmart (2:23-cv-00418) over the use of certain web tracking technologies (e.g., beacons, cookies, and pixels) and provision of their respective online advertising systems, Retail Media+ and Walmart Connect. The plaintiff describes one of the two patents-in-suit as generally related to “an advanced machine-to-machine automation technique that stores encoded information at a client device on the basis of network resource requests determined by a server” and the other as broadly directed to “improved advertising systems that enable tiered bidding, cross-selling, and retargeting in online marketing systems”.

Bjorn Markus Jakobsson has moved patents around, from prior plaintiff RightQuestion LLC to Carbyne LLC this past December and then from Carbyne to Carbyne Biometrics, LLC just last week. Carbyne Biometrics has accused Apple (1:23-cv-00324) of infringing six of those received assets—three characterized as “Authentication Patents” and three, as the “Fraud Reduction Patents”—in a new Western District of Texas complaint that targets the provision of “all of its M-series Macs and A-series iOS devices”. At issue is its authentication framework, comprised of the Secure Enclave, Face ID, Touch ID, and related tools (e.g., the Apple Cash fraud prevention tools). One of the six patents appeared in an Eastern District of Texas case between RightQuestion and Samsung that ended in July 2022.
