Narrative Opinion Summary
In this case, the United States Court of Appeals for the Federal Circuit reviewed an appeal involving the rejection of patent claims under 35 U.S.C. § 101 for being non-statutory subject matter. The court examined the jurisdiction and authority of the Board of Patent Appeals and Interferences, focusing on whether the Board's reconsideration constituted a valid rehearing. The Commissioner of Patents' authority to form new panels and the interpretation of 'rehearings' under 35 U.S.C. § 7(b) were central issues. The court concluded that Alappat's claimed invention, a digital oscilloscope rasterizer, qualifies as a machine and thus constitutes patentable subject matter, reversing the Board's rejection. The court also addressed procedural concerns regarding the Board's composition, emphasizing that procedural challenges were waived by the parties. The decision underscored the importance of interpreting means-plus-function claims in line with disclosed structures, while reaffirming the Commissioner's supervisory oversight over the Board. Despite dissenting opinions on procedural and jurisdictional grounds, the court maintained its jurisdiction to review the merits, ultimately ruling in favor of patentability for Alappat's claims.
