Google co-founder Sergey Brin took square aim at the shortcomings of U.S. patent law during his onstage interview at the Code Conference, saying the system “could be improved greatly, by many metrics.” Specifically, he argued that business process patents, which cover new methods of doing business, should be eliminated. Brin added that patent holders should be required to put the protected technology to use, taking issue with what he called “patent trolls,” who often lock up intellectual property for the purpose of charging for its use, usually under threat of lawsuit.
