In 2010, the Supreme Court denied patent protection for a system for processing how "commodities buyers and sellers in the energy market can protect, or hedge, against the risk of price changes". Business method patents are no longer eligible under the United States Patent Act, 35 U. S. C. §101.
Purely abstract ideas such as business methods are not patentable.
