What the complaint alleges

GATX Corporation sued Big Will Enterprises Inc. in the U.S. District Court for the Northern District of Illinois, seeking a declaratory judgment that GATX does not infringe eight patents owned by BWE. GATX alleges that BWE, a non-practicing entity, sent a demand letter accusing GATX's PIVOT railcar telematics system of infringement and threatening litigation unless licensing fees were paid.
