Court of Appeals for the Eleventh Circuit July 9, 1982, No. 80-5333 (Manufacturing Research Corp. v. Graybar Electric Co.)

VANCE, Circuit Judge:

This appeal involves the validity of three patents held by plaintiffs for manual and hydraulic cable benders. After a jury trial, the district court held the three patents valid and held that defendant had infringed them by manufacturing and marketing two cable benders, one manually operated and one hydraulically operated. We reverse and remand for further proceedings.
