Brooks v. Dunlop Mfg., Inc., No. 12-1164 (Fed. Cir. 2012)Annotate this Case
Under 35 U.S.C. 292(a) it is unlawful to engage in specified acts of false patent marking, such as affixing a mark that falsely asserts that the item is patented, with intent to deceive the public. Prior to 2011, the statute authorized private parties (relators) to bring a qui tam or informer’s suit for violations, but did not specify procedures or authorize the government to file its own suit to collect the penalty. The 2011 AIA eliminated the qui tam provision, but authorized actions for damages by any person “who has suffered a competitive injury as a result of a violation.” The AIA provides that marking products with expired patents is not a violation and that it applies to all pending cases. In 2010, Brooks sued, alleging that Dunlop marked a guitar string winder with the number of a patent that was both expired and invalidated. The AIA was enacted while the case was stayed, pending the outcome in another case. The district court held that the application of the AIA to pending actions did not violate the Due Process Clause and that the legislation rationally furthered a legitimate legislative purpose. The Federal Circuit affirmed.
