Summary

Background

The case involved the Commissioner of Patents and Trademarks and Bradley, arising from a dispute that reached the Supreme Court from the United States Court of Customs and Patent Appeals. The parties argued the case on October 14, 1980, and the Court issued its decision on March 9, 1981. The published disposition is a short per curiam statement. Numerous outside groups and companies filed supporting briefs: National Semiconductor urged reversal, several patent law associations and Applied Data Research urged affirmance, and Halliburton Services also filed a brief.

Reasoning

The Court’s entire text states only that the judgment below is affirmed by an equally divided Court. There is no signed majority opinion in the published decision explaining the Justices’ legal reasoning. The Chief Justice did not take part in consideration or decision of the case. Because the Court was evenly split, the Supreme Court did not produce a controlling authored opinion resolving the contested legal questions in the record before it.

Real world impact

As a practical matter, the immediate effect is that the lower court’s judgment remains in force for the parties involved, so the outcome reached below stands. The split decision records the strong interest of industry and patent-law groups, but the opinion itself does not set out new guidance or a detailed rule for other cases. The Court’s brief, per curiam affirmance leaves the underlying legal issues unresolved at the Supreme Court level.
