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 42 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.

One reason for this rule is that * * * the monopoly of a single invention might be * * * greatly extended.” Emphasis supplied)”
