KSR vs Teleflex was a court case at the US Supreme Court. The opinion of the court was written by Justice Kennedy.

This case raised the bar for the "obviousness" test, saying that a:

combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.

This decision lead to a revision of the USPTO's examiner guidelines.[1]

For the period 2007-2010, it was the third most cited patent case by the CAFC.[2]
