District Court infringement determination vacated in L&W v. Shertech

The CAFC found, contrary to the district court, that L&W had not acknowledged embossments separate the layers of its heat shields.

There was an issue of inconsistent jury verdicts, and the CAFC cited Minn. Min. v. Chemque, 303 F.3d 1294. Perkin-Elmer v. ComputerVision, 732 F.2d 888, is also cited.
