  • District Court: patent is invalid
  • Court of Appeals: patent is valid
  • Supreme Court: patent is invalid


  • patentability is said to come from combination of heater and standard paving machine
  • radiant-heat burner patented in 1956 by Schwank
  • operation of the heater is not dependent on operation of the paving machine


  • combination of heater and paving machine is a convenience; does not produce a "new or different function"; combination NOT greater than the sum of parts
  • filled a long-felt want; commercial success
    • does not prove nonobviousness
