ZapFraud, Inc., an entity formed by Bjorn Markus Jakobsson, has initiated a litigation campaign, suing Barracuda Networks (1:19-cv-01687), FireEye (1:19-cv-01688), Fortinet (1:19-cv-01689), Mimecast (1:19-cv-01690), and Proofpoint (1:19-cv-01691) in separate cases filed in the District of Delaware. A single patent naming Jakobsson as sole named inventor, and which generally relates to secure electronic communications, is asserted in each complaint with the defendants accused of infringement through the provision of email security products and services that allegedly “protect customers against email-based targeted social engineering attacks known as Business Email Compromise”, including emails where the sender is impersonating someone else.

Inventor-controlled Crypto Research, LLC has filed its first case, asserting three related cryptography patents (8,086,866; 8,516,262; 8,990,576) against ASSA Abloy and HID Global (2:16-cv-01718). The patents-in-suit generally relate to the computation of one-way chains, and the new NPE accuses the defendants of infringement through validation services provided as part of their CoreStreet and ActivIdentity products.
