The Supreme Court in KSR International Co. v. Teleflex Inc. clarified its 1966 decision in Graham v. John Deere, avoiding the sea change to a synergy-based standard that many had expected—and perhaps feared. KSR has raised the bar set in Graham for seeking patent protection—by providing a flexible test for obviousness—while simultaneously making it easier for accused infringers to defend themselves. Moreover, KSR will change the strategies of both patent prosecutors and litigators.
