The Supreme Court affirmed the judgment of patent ineligibility in "Bilski v. Kappos". It did not endorse the use of the machine-or-transformation test as the sole test, but said it was only a "useful clue" to making the determination. The Court's majority also declined to hold business methods categorically patent ineligible. Four Justices, however—Justice Stevens, concurring, joined by Justices Breyer, Ginsburg, and Sotomayor—would have held all business methods patent ineligible, on the basis of the historical background of the patent clause of the Constitution. In a separate concurring opinion by Justice Breyer, he listed points on which the Court unanimously agreed. One point was that the "State Street Bank" case was not a correct statement of the law.
