In re Deckler, 977 F.2d 1449, 24 U.S.P.Q.2d 1448

Facts

The appellant, Deckler, sought a patent for an improved seed planter. In an interference proceeding, the Board awarded priority of invention to Grataloup, who had filed a foreign patent application. Although Deckler was the first to reduce the invention to practice, he suppressed it until after Grataloup's priority date. The Board later affirmed the examiner's rejection of Deckler's claims, stating they were not patentably distinct from the claim involved in the interference.

The appellant Deckler seeks a patent for an improved seed planter. In an interference proceeding under the 'old' rules between Deckler and Grataloup, involving a claim the examiner had suggested to Deckler, the Board awarded priority of invention to Grataloup.

Issue

Whether the Board correctly ruled that the losing party in an interference proceeding was not entitled to a patent covering claims that that party admits are patentably indistinguishable from the claim involved in the interference.

The sole issue in this appeal from the Board of Patent Appeals and Interferences (Board), is whether the Board correctly ruled that the losing party in an interference proceeding was not entitled to a patent covering claims that that party admits are patentably indistinguishable from the claim involved in the interference.

Rule

Under principles of res judicata and collateral estoppel, a judgment in an action precludes relitigation of claims or issues that were or could have been raised in that proceeding. This means that if a party loses an interference proceeding, they cannot obtain a patent for claims that are not patentably distinct from the claims involved in that interference.

Under principles of res judicata and collateral estoppel, judgment in action precludes relitigation of claims or issues that were or could have been raised in that proceeding.

Analysis

The Board applied the principles of res judicata and collateral estoppel to reject Deckler's claims, as they were found to be patentably indistinguishable from the claim on which he lost the interference. The Board reasoned that allowing Deckler to obtain a patent for these claims would lead to an unfair situation where two patents could be issued for the same inventive concept, which is contrary to the intent of patent law.

The Board correctly noted the unfortunate consequences that would follow if the interference judgment were not given that preclusive effect. There would be a second interference between Deckler's claims 'and the claims of Grataloup. Furthermore, this interference would be declared with respect to subject matter identical to the subject matter of the count in the original Deckler/Grataloup interference.'

Conclusion

The court affirmed the Board's decision, concluding that Deckler was barred from obtaining a patent for claims that were not patentably distinct from the claim involved in the interference.

The decision of the Board is AFFIRMED.

Who won?

Grataloup prevailed in the interference proceeding, which was pivotal in determining the outcome of Deckler's appeal. The Board's decision was based on the principle that only one patent should issue for inventions that are not patentably distinct from each other. Since Deckler conceded that his claims were indistinguishable from the interference count, the Board correctly applied res judicata and collateral estoppel to bar his claims.
