Fromson v. Western Litho Plate and Supply Co., 853 F.2d 1568, 7 U.S.P.Q.2d 1606

Facts

Howard A. Fromson, the inventor and owner of a patent for a photographic plate used in planographic printing, initiated a patent infringement action against Western Litho Plate and Supply Co. The United States District Court for the Eastern District of Missouri found that Fromson's patent was valid and infringed by Western's grained-and-anodized plates. The court imposed a licensing agreement requiring Western to pay royalties at a rate of 0.825% on the infringing products. Western appealed the decision, challenging the validity of the patent and the reasonableness of the royalty.

Alleged infringer of patent on photographic plate for use in planographic printing did not carry its burden of overcoming presumption of patent's validity, notwithstanding its claims that district court had elevated that presumption to unsurmountable level and had otherwise acted improperly.

Issue

Did the infringer overcome the presumption of the patent's validity, and was the royalty rate imposed reasonable?

Did the infringer overcome the presumption of the patent's validity, and was the royalty rate imposed reasonable?

Rule

Analysis

The court determined that Western failed to meet its burden of proving the patent's invalidity, as it misinterpreted the prosecution history and did not provide sufficient evidence of prior invention. The court also found that the delay in bringing the infringement action was not due to bad faith on Fromson's part, thus laches did not bar recovery. However, the court concluded that the royalty rate of 0.825% was not reasonable given the circumstances and the evidence presented.

Who won?

The court's ruling emphasized that Western did not successfully challenge the presumption of validity and that the delay in bringing the action did not constitute laches. However, the court recognized that the royalty rate imposed was unreasonable, indicating that while Fromson won on the infringement issue, further proceedings were necessary to determine appropriate damages.
