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.

Using Aerospace Approach, Engineers Design Wave Energy System

Aerospace engineers from the U.S. Air Force Academy are applying the principles that keep airplanes aloft to create a new wave energy system that is durable, efficient, and can be placed anywhere in the ocean - regardless of depth. While still in early design stages, computer and scale-model tests of the system suggest higher efficiencies than wind turbines.

NASA's Algae Bioreactor Licensed to Algae Systems, LLC

Earlier this year, NASA introduced an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel and a variety of other products. The NASA bioreactor is an Offshore Membrane Enclosure for Growing Algae (OMEGA), which won't compete with agriculture for land, fertilizer, or freshwater.
