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.

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.

Another entity formed by Bjorn Markus Jakobsson has kicked off litigation, RightQuestion LLC suing Samsung (2:21-cv-00238) over two biometric authentication patents. Targeted in the new Eastern District of Texas complaint is Samsung’s provision of Knox Vault, a secure information storage system that uses biometric authentication and is included in its Galaxy S21 smartphone. Each of Jakobsson’s prior litigation campaigns, the first filed through Crypto Research, LLC and the second, through ZapFraud, Inc. saw the asserted patents challenged with an early Alice motion—leading to very different results.
