Shipping & Transit, LLC appears to have taken over a vast and infamous litigation campaign that was initiated by ArrivalStar SA and Melvino Technologies Limited over a decade ago. Since April 2015, Shipping & Transit has sued 56 companies, mostly retailers, over a group of former ArrivalStar patents generally related to shipment tracking and scheduling (6,904,359; 6,975,998; 7,030,781; 7,400,970). Shipping and notification services (e.g. an e-mail to a customer that includes a tracking link) have been the accused products throughout this campaign, and that focus continues in the latest suits, filed last week against Campmor (2:15-cv-08635), Freshpair (2:15-cv-08638), Glasses USA (2:15-cv-08641), and Suntek Systems (9:15-cv-81529). Out of the 55 cases filed in this campaign, only 15 remain active. Most have been dismissed with prejudice, many within three months of filing.
