Powell v. Home Depot U.S.A., Inc., No. 10-1409 (Fed. Cir. 2011)Annotate this Case
Plaintiff designed a radial arm saw guard and sold eight prototype units for use by defendant, a major retailer, at stations for cutting lumber. Defendant contracted with another to make copies of the guard for all of its stores at a lower price. The district court concluded that plaintiff had not committed inequitable conduct and declined to hold plaintiff's patent unenforceable. The court made findings of willful infringement and bad faith litigation and awarded enhanced damages and attorney fees. The Federal Circuit affirmed, finding the willful infringement and damages determinations are supported by substantial evidence. The trial court properly construed the claim terms "dust collection structure" and "table top."
