Marc Brown was interviewed by the EE Times for its May 2 issue regarding the U.S. Supreme Court's ruling on KSR v. Teleflex. While the decision clearly rejected a "rigid rule" test, the Court wasn't explicit about what takes its place. “What they have been less clear about is what the new test is. Some of the most controversial patents of recent years have been so-called ‘business method’ patents, such as a company patenting a particular way of doing business. One such example is a long-running case involving eBay and its 'buy it now' option, which a jury decided violated a patent held by a small company, MercExchange. Business method patents already are difficult to get, and this ruling will make it even more so. They're going to be much more prone to attack," said Mr. Brown.
