Should business methods be eligible for patents?

This week's question concerns patent law. Traditionally, the courts have limited patent eligibility to inventions that involve machinery or physical transformations. Increasingly, innovations in the areas of software, medical diagnostics, and finance have raised questions concerning the eligibility of these inventions for patents because they may not deal directly with machinery or physical processes. Earlier this month, the Supreme Court heard the case of two individuals seeking patent protection for a business method of hedging risk in buying energy. On the opposing side, the attorney for the U.S. Patent and Trademark Office argued that though innovative business techniques "may be valuable ... they are not patent eligible because they don't deal in the realm of the physical." What do you think? Should business methods be eligible for patents?

New Pathway to Forming Hydrogen Storage Compounds

Scientists at the Carnegie Institution for Science have found that high pressure can be used to make a unique hydrogen-storage material. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen under pressure to form a previously unknown solid with unusual bonding chemistry.
