Case law in the USA

Case law in the USA is the collection of rulings handed down by the courts that deal with patents in the USA. Case law provides the official interpretations of the legislation.

The highest court, the US Supreme Court, has not directly examined the question of the patentability of software ideas, but it has taken decisions on closely related patentable subject matter in a triplet of cases in the 70s and early 80s (Benson, Flook, Diehr), and in the 2010 Bilski v. Kappos case.

A lower court, the US Court of Appeals for the Federal Circuit (CAFC) has upheld many software patents.

It will take time for case law to be developed around the Bilski decision of 2010. See: patentability in the USA after Bilski.
