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 14 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“[t]he policy of the Patent Office in permitting product-by-process type claims to define a patentable product, where necessary, has developed with full cognizance of. the fact that in infringement suits some courts have construed such claims as covering only a product made by the particular process set forth in the claim and not to the product per se.”
2 later decisions quote this exact passage“We must approach the issue of patentability in terms of what would have been obvious to one of ordinary skill in the art at the time the invention was made in view of the sum of all the relevant teachings in the art, not in view of first one and then another of the isolated teachings in the art.”
