Document:
'''Case law in the USA''' is the collection of rulings handed down by the [[USA patents courts and appeals|courts that deal with patents]] in the [[USA]].
The highest court, the [[US Supreme Court]], has not examine [[patentable subject matter]] since the 1981 case [[Diamond v. Diehr (1981, USA)|Diamond v. Diehr]]. This case was interpreted by some as validating software patents, but this position is far from clear. Since then, the [[US Court of Appeals for the Federal Circuit]] (CAFC) has upheld many software patents.
A change occurred in 2008 when the CAFC rejected a [[business method patent]] in the case [[in re Bilski]]. The test they used, known as the [[machine-or-transformation test]], also narrows or closes the scope for patenting software ideas. The Supreme Court is reviewing this new test in the [[Bilski v. Kappos]] case.
The highest court, the [[US Supreme Court]], has only ruled on certain aspects of the software and [[patentable subject matter]]. From the 70s and early 80s, there's [[Gottschalk v. Benson (1972, USA)|Benson]], [[Parker v. Flook (1978, USA)|Flook]], and [[Diamond v. Diehr (1981, USA)|Diehr]]. More recently there's [[Bilski v. Kappos|Bilski (2010)]] and [[Alice v. CLS Bank ruling by US Supreme Court on 19 June 2014|Alice v. CLS (2014)]] and one important non-software case, [[Mayo ruling by US Supreme Court on 20 March 2012|Mayo (2012)]].
A lower court, the [[US Court of Appeals for the Federal Circuit]] (CAFC) has upheld many software patents but the Bilski and Alice rulings by the Supreme Court should reduce the CAFC's ability to continue doing so.
