Inventor-controlled NPE Ameranth, Inc. has filed its first complaint in over two years, suing DoorDash (2:22-cv-01776) in the Western District of Pennsylvania over the provision of the DoorDash Iguazu System Framework, a “real time event processing system” used in its delivery platform. The asserted patent, appearing in litigation for the first time, generally relates to an “intelligent web server computer” for use in “completing remotely initiated hospitality food/drink delivery or pick up ordering tasks”.
