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. These counts are smaller than the citation total above because most of the 6 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.

Under § 103, the scope and content of the prior art are to be determined; differences between the prior art and the claims at issue are to be ascertained, and the level of ordinary skill in the pertinent art resolved.”
