KSR International Co. v. Teleflex Inc.

KSR International Co. v. Teleflex Inc. is a 2007 U.S. Supreme Court case that addressed how courts should determine if a patent claim is obvious and therefore not valid. The Court emphasized that obviousness should be judged based on the common sense of a person skilled in the field, considering factors like prior inventions and knowledge. This ruling made it more challenging to get patents for ideas that are straightforward or predictable, aiming to prevent overly broad patents that could stifle innovation. The decision clarified the criteria for patentability, balancing innovation protection with public access.
