In re Fought – On November 4, 2019, the Federal Circuit reversed the PTAB , finding Appellant’s claims were not anticipated on the grounds that a preamble term, “travel trailer”, was limiting. When determining the scope of “travel trailer”, the Federal Circuit looked to extrinsic evidence (Woodall’s RV Buyer’s Guide) and found that “travel trailer” is a specific type of recreational vehicle that includes living quarters. Therefore, “travel trailer” is a structural limitation and not just a mere statement of intended use, as the government asserted. The court remanded the case for further proceedings consistent with the interpretation of “travel trailer” as a limiting term.
