Plano Encryption Technologies, LLC (PET) has recently added cases against Alkami (2:16-cv-01032), Best Buy (2:16-cv-01049), Etsy (2:16-cv-01050), and Shutterfly (2:16-cv-01053) to its sole litigation campaign. The new complaints assert two patents (5,991,399; 5,974,550) generally related to security in online transactions, targeting the defendants’ mobile apps. At roughly the same time, the court granted dismissals, all but one with prejudice, in earlier cases in the campaign, all of which were brought against banks or providers of online and mobile banking applications.
