Narrative Opinion Summary
This case involves a patent interference dispute between a French corporation, Stryker Spine, and the defendants, Biedermann Motech GmbH and DePuy Spine, Inc., reviewed by the United States District Court for the District of Columbia. Stryker sought judicial review of the PTO's Board of Patent Appeals and Interferences' decision under 35 U.S.C. § 146, contesting the Board's declaration of a single interference count between its '460 Patent and the defendants' '431 Application. Stryker argued that the Board should have recognized two distinct inventions: 'intersecting bores' and 'intersecting planes.' The court previously denied Stryker's motions for summary judgment, leading to a bench trial. During the trial, expert witnesses from both sides presented their analyses, focusing on whether the proposed counts were patentably distinct. The court concluded that the inventions were not distinct, as both could be considered obvious to a person of ordinary skill in the art, affirming the Board's decision to maintain a single interference count. Consequently, Stryker's remaining claims, dependent on a redefined interference count, were dismissed, resulting in a judgment in favor of the defendants and the dismissal of Stryker's action.

Application: Stryker failed to meet the burden of proving that the existing interference count comprised two distinct inventions.
Reasoning: A party seeking to redefine counts must prove that the existing count comprises two distinct inventions, where prior art for one would not anticipate or render the other obvious.
Judicial Review under 35 U.S.C. § 146subscribe to see similar legal issues
Application: The court reviews the Board of Patent Appeals and Interferences' decision de novo, focusing on whether an interference count was properly declared.
Reasoning: Judicial review under this section is a hybrid of an appeal and a trial de novo, where legal questions are reviewed de novo and factual determinations for clear error.
Obviousness and Patentabilitysubscribe to see similar legal issues
Application: The court determined that the claims in question were not patentably distinct, as a person of ordinary skill in the art would find the inventions obvious.
Reasoning: Consequently, the Court determined that claim 1 is obvious in light of claim 18, and vice versa, concluding that Stryker’s proposed interference Counts 2 and 3 do not depict patentably distinct inventions.
