CompFox AI Summary
This is a patent infringement suit where Kothmann Enterprises, Inc. (KEI) alleged that Trinity Industries, Inc. (Trinity) infringed two of its patents, U.S. Patent No. 6,022,003 (the ’003 Patent) and U.S. Patent No. 6,505,820 (the ’820 Patent), with its roadside safety devices, the MPS-350 and TRACC. Trinity denied infringement and asserted the patents were invalid. The court granted KEI's motion for summary judgment regarding ownership of the patents. However, the court found that Trinity's MPS-350 and TRACC devices did not infringe the asserted claims of either the ’003 or the ’820 Patent, literally or under the doctrine of equivalents, thus granting Trinity's motions for non-infringement. Furthermore, the court denied Trinity's motions for summary judgment regarding the invalidity of the ’003 and ’820 Patents, concluding that they were not invalid for lack of a written description or anticipation by prior art.
