The Federal Circuit vacated and remanded the PTAB's decision regarding Anticipation in the case of American Science and Engineering v. Stewart. The invention consists of an X-Ray inspection system designed for moving objects, which requires two perpendicular pencil beam directions concerning the object's trajectory. In the IPR, PTAB had previously indicated some claims were anticipated by "Seppi," prompting AS&E to appeal. The Federal Circuit found that the Board did not sufficiently support its conclusions, specifically not demonstrating that Seppi's scatter detectors could detect radiation from the required two sources.
The Federal Circuit vacated and remanded the PTAB's anticipation conclusion, identifying gaps in the Board's analysis concerning the X-Ray inspection system claims.
The invention involves an X-Ray inspection system for moving objects, requiring two pencil beams shot in perpendicular directions.
AS&E argued the PTAB's finding was lacking in substantial evidence, alleging that it did not properly address critical aspects of Seppi's scatter detectors.
The central complaint highlighted that the Board failed to establish that Seppi's detectors could recognize scattered radiation from the two beam sources.
