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 12 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““Of course we must find that the Board of Appeals erred in its decision before we can reverse it. The fact that strong equities may exist in favor of appellant does not justify us in finding error where none exists, but we think it is proper for us to consider these facts in determining the weight to be given to the fact that all of the tribunals of the Patent Office concurred in finding laek of patentability in appellant’s claims. We have a right to consider that a patent has been issued by the Patent Office, a patent covering the very claims here in issue, that such patent is beyond recall by it, and that it will be considered in any court as presumptively valid.””
