#35-usc--101

The Federal Circuit affirmed that a patent claiming natural language processing using case-based reasoning on a metadata database is ineligible under 35 U.S.C. § 101, establishing that applying established AI techniques to new fields does not overcome patent ineligibility.

CAFC affirmed dismissal, holding the asserted software claims were directed to the patent‑ineligible abstract idea of asynchronous presentation review, not a specific technological improvement.
