How later courts describe this case

  • “These factors were entitled to weight in determining whether the improvement amounted to invention and should, in a close case, tip the scales in favor of patentability.”
  • secondary considerations important because claim not clearly obvious
  • simplicity of itself does not negate invention

Headnotes

  1. Patent Law — Standard of Review Concurrent findings of fact made by the district court and the circuit court of appeals in a patent infringement suit will not be set aside unless clearly erroneous, and it must be a strong case for the Supreme Court to disturb such concurrent findings of two lower courts. 321 U.S. at 278
  2. Patent Law — Patentability — Invention The fact that a patented means, viewed after the event, appears simple and such as should have been obvious to those working in the field does not suffice to negative invention; where a long-felt problem in a crowded art went unsolved for half a century despite widespread awareness of the defects, and the eventual solution achieved marked commercial success, those factors are entitled to weight in determining whether the improvement amounts to invention and, in a close case, tip the scales in favor of patentability. 321 U.S. at 279
  3. Patent Law — Validity Defenses to a patent infringement suit based on asserted insufficiency of the description of the invention and on alleged file-wrapper estoppel will not be sustained where the proofs do not support them. 321 U.S. at 279
  4. Patent Law — Infringement A patent is infringed where the accused device, though substituting structure and material, does no more than make a choice of mechanical alternatives and thereby practices the principle disclosed by the patent; conscious copying of the patentee's commercial product supports a finding of infringement. 321 U.S. at 278
  5. Patent Law — Patentability — Question of Law (Dissenting Opinion) Whether the thing patented amounts to a patentable invention is a question of law to be decided by the courts; patents should not be granted for microscopic structural or mechanical improvements, and invalidating a patent is appropriate where the alleged discovery does no more than apply knowledge long the universal possession of all peoples. 321 U.S. at 280–281 (Black, J., dissenting)
