 The court notes that "simple logic" suggests that trying again with new addresses, rather than failed addresses, as directed by the patented method, would have been obvious to try.The Federal Circuit rejected Perfect Web's arguments that the patent satisfied a long-felt need because they failed to provide any evidence of improved efficiency beyond "bare assertion".The court, referencing Asyst Techs., Inc. v. Emtrak, Inc., suggested that any proof of long-felt need would be insufficient to "overcome [the] strong prima facie showing of obviousness."
