TriMas Corp. today (April 22) announced that the federal district court in Colorado entered multiple summary judgment rulings in favor of TriMas’ Cequent Americas business in a patent infringement lawsuit against Wyers Products Group Inc.

TriMas reported in a news release that the dispute involved multiple patents for hitch receiver locks and universal trailer coupler locks. In its decision, the federal court ruled that Wyers’ UMAX50 and UMAX100 universal trailer coupler locks, which Wyers sells under the Trimax brand, infringe Cequent’s U.S. Patent No. 6,722,686 (Cequent’s ‘686 patent). The federal court also rejected Wyers’ claim that Cequent’s ‘686 patent is invalid.

The federal court further determined that Cequent did not infringe, as a matter of law, the two patents that Wyers raised in this dispute, U.S. Patent Nos. 7,121,121 and 6,672,115.
