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 35 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““A comparison of the two patents requires an interpretation of the original patent in the light of the state of the art at the date when the application for it was filed. And we have the material for ascertaining its meaning in that view by means of the evidence on that point contained in the record, which, although objected to on the ground that no prior knowledge or use of the invention claimed had been specifically set up in the answer as a defense, was nevertheless admissible for the purpose of defining the limits of the grant in the original patent, and the scope of invention described in its specification.””
