In its long awaited decision in KSR International Co. v. Teleflex, Inc., 127 S. Ct. 1727 (April 30, 2007), the United States Supreme Court has completely changed the patent landscape. The Court held that the test used by the Federal Circuit Court of Appeals to determine obviousness under 35 U.S.C. §103 is incorrect. Because of KSR, it will now be harder to get patent claims allowed and easier to invalidate issued patents.
In KSR, Teleflex sued its competitor KSR, in the Eastern District of Michigan for patent infringement of Teleflex’s patent for an automobile pedal assembly. The invention combined an electronic sensor with an automobile pedal so that the pedal position could be communicated to a computer controlling the automobile’s throttle. KSR contended that the relevant claims of Teleflex’s patent were obvious under section 103.
