  • On April 30, the Supreme Court handed down its highly anticipated decision in KSR International Co. v. Teleflex, Inc. The Court ruled that the Federal Circuit's "teaching, suggestion, or motive" test cannot rigidly be applied as a mandatory threshold showing in the assertion of an "obviousness" defense to patent infringement. Continuing the theme set forth in its recent eBay v. MercExchange decision, the Court criticized the mechanical application of patent doctrine to issues that call for flexibility and the appreciation of nuance.
