KSR v. Teleflex: http://www.supremecourtus.gov/opinions/06pdf/04-1350.pdf
Held: the standard of "obviousness" used by the Federal Circuit is too narrow. This should lead to a greater invalidation of patents on the grounds that they do not satisfy the requirement of the paptent statute that improvements or inventions be "non-obvious."
