Trial is set for early June in the Western District of Texas case brought by Caddo Systems, Inc., as owner of the asserted patents, and exclusive licensee 511 Technologies, Inc. against Microchip Technology. District Judge Alan D. Albright is in receipt of a slew of pretrial motions, a hearing concerning which was held on May 18. Two days later, the plaintiffs filed a new case in the campaign, this one in the Eastern District of Texas against Texas Instruments (4:22-cv-00434), following up a week later with separate suits against LightInTheBox (2:22-cv-00732), in the Western District of Washington, and Progress Software (1:22-cv-10815), in the District of Massachusetts. Asserted are overlapping sets of patents generally directed to hierarchical menu navigation, with infringement allegations again targeting the provision of nested menus on product platforms and/or company websites.
