Citation
561 U.S. 593 (2010)
Court
Supreme Court of the United States
Date
28 June 2010
Bench
Full Court; Kennedy J. delivered the controlling opinion

Facts

  • Bilski and Warsaw applied for a patent covering a method of protecting buyers and sellers of commodities against price changes.
  • The method involved:
  • identifying market participants with opposing risk positions;
  • entering transactions that balanced those risks;
  • applying mathematical relationships to energy-market hedging.
  • The Patent Office rejected the claims.
  • The Federal Circuit held that a process was patent eligible only if it:
  • was tied to a particular machine; or
  • transformed a particular article.
  • Bilski’s method satisfied neither branch.
  • The applicants appealed to the United States Supreme Court.

Issue

  • Whether the machine-or-transformation test is the exclusive test for patentable processes.
  • Whether business methods are categorically excluded from patents.
  • Whether Bilski’s hedging method was an unpatentable abstract idea.

Rule

  • Patent law extends to new and useful processes, but excludes:
  • laws of nature;
  • physical phenomena;
  • abstract ideas.
  • The machine-or-transformation test is a useful and important clue.
  • It is not the sole or exclusive test for every process, particularly as technology develops.
  • Business methods are not categorically excluded merely because they concern commerce.
  • However, describing an abstract economic principle as a series of steps does not make it patent eligible.
  • Limiting an abstract idea to a particular field or adding token post-solution activity is insufficient.

Application

  • Hedging against price fluctuation was a long-established economic practice.
  • Bilski’s claims broadly covered the concept of balancing risk between market participants.
  • The claims were not limited to:
  • a particular machine;
  • a specific technological system;
  • a defined industrial transformation.
  • Allowing the patent would risk granting control over the basic idea of commodity-risk hedging.
  • The Court rejected the Federal Circuit’s attempt to turn the machine-or-transformation test into an absolute statutory rule.
  • Future technologies might involve useful processes that do not fit neatly within either category.
  • Nevertheless, Bilski’s claims failed under the established abstract-idea exclusion.
  • The Court also declined to declare every business method unpatentable.
  • The statute’s wording and history did not support such a blanket exclusion.
  • Some business-related inventions might involve a genuine technological application.
  • Bilski’s application, however, did not claim a specific technical implementation.
  • It largely restated an economic concept and instructed users to apply it in the energy market.
  • Restricting the idea to one commercial field did not supply an inventive technological character.
  • The Court therefore avoided adopting an exhaustive eligibility test but confirmed that abstract economic principles remain outside patent protection.

Conclusion

  • The Supreme Court held that the machine-or-transformation test is not exclusive.
  • Business methods are not automatically unpatentable.
  • Bilski’s particular claims were nevertheless invalid because they sought to patent the abstract idea of hedging risk.
  • Use this case for: machine-or-transformation is an important indicator, but a process still fails where it merely claims an abstract economic idea without a concrete inventive application.
