Delaware plaintiff Secure Ink LLC has filed its first litigation, suing Box (6:24-cv-00072) and Dropbox (6:24-cv-00074) in the Western District of Texas, DigiSigner (2:24-cv-00076) in the Eastern District of Texas, and DocuFirst (4:24-cv-00417) in the Southern District of Texas over a single patent generally related to an “electronic mortgage closing document processing system”.
