AT&T (2:24-cv-00588) is the latest defendant to be added to the sole litigation campaign of Quantum Technology Innovations, LLC (QTI), launched in April 2022. In the new Eastern District of Complaint, AT&T is accused of infringing a single patent—generally related to a server running a computer program for distributing content over a network—through the provision of the AT&T Content Delivery Network (CDN). At issue is the alleged use of a “geographically distributed network of edge servers or Points of Presence (POPs) to provide immediate content access for the end users”.
