Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work.

“Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.”
5 later decisions quote this exact passage · from the dissent“Our reference in Christensen to the mathematical equation as being “at the point of novelty” does not equate to a holding that a claim may be dissected, the claim components searched in the prior art and, if the only component found novel is outside the statutory classes of invention, the claim may be rejected under 35 U.S.C. § 101 . That procedure is neither correct nor within the intent of Congress, for the reasons we stated in [In re Bernhart, 417 F.2d 1395 , 57 CCPA 737 , 163 USPQ 611 (1969)].”
