Rite-Hite Corp. v. Kelley Co.

Court of Appeals for the Federal Circuit
56 F.3d 1538 (1995)


Rite-Hite (plaintiff) sued Kelley (defendant) for infringing the ‘847 patent, which claimed a restraint safety device for truck loading docks. The district court found the patent valid and infringed by Kelley, who appealed to the Federal Circuit. The Federal Circuit affirmed the finding of validity and infringement, and remanded solely on the issue of damages Rite-Hite, on remand, sought lost profits based on two models of devices it sold; however, only one of those two models was covered by the ‘847 patent. The district court awarded damages based on lost profits as to both restraint devices. The district court also awarded lost profits for sales of competing unpatented but complementary leveling products, which are platforms sold with and operate in conjunction with the safety device by bridging the gap between the back of the truck and the dock. Kelley appealed the damages determination to the Federal Circuit.
