Summary

Background

Hartford‑Empire owned a "gob feeding" patent and had earlier won a judgment finding another company guilty of infringement. Hartford used that earlier judgment and a spurious Clarke article in later suits to obtain infringement decrees against Shawkee and several other manufacturers. Shawkee raised suspicions about the Clarke article while an appeal was pending but lacked direct proof until government evidence appeared in a later antitrust case.

Reasoning

The Court asked whether the differences in timing and procedure meant the later judgments should still stand. It concluded they should not. Hartford had successfully used the earlier judgment without revealing its prior misconduct, and its failure to disclose the fraudulent scheme aggravated the prior deception practiced on the Patent Office and the courts. For that reason the Court reversed the Circuit Court of Appeals, directed that the prior appellate mandate be recalled, ordered the district court’s infringement judgment set aside, and denied Hartford all relief under the patent.

Real world impact

Companies like Shawkee that were previously ordered to pay or stop using the patented method are freed from those obligations for now and may return to district court to pursue further relief. The Court also allowed Shawkee and the others to seek an accounting of costs, payments made under the judgments, and damages caused by Hartford’s unlawful use of the patent. Those remedies will depend on further proceedings in the district court.

Dissents or concurrances

A separate opinion by Justice Roberts (joined by two others) agreed with reversal but would have sent the parties back to seek leave to file a bill of review in the district court instead of the majority’s direct directives.
