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 4 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““ * * * , These tests were sufficient to-prove conclusively the character of vulcanization attained. If laboratory tests and laboratory construction of inventions were to be rejected in eases of this kind, it would seem to us that it would lead to very grave consequences for future inventions. It may be that there are in the field of invention certain articles in which laboratory tests and laboratory manufacturing would hardly be regarded as a reduction to practice', but we do not think vulcanization of rubber can be placed in that class. * * * “True enough, those! who contemplate great expenditures in manufacturing establishments and equipment ofttimes apply many different teste in order to determine the commercial expediency of wholesale manufacture, but, because this is a practice among careful and responsible manufacturers, it does not follow that such a practice is the measure by which the patent tribunals should determine the question of reduction to practice in a ease like that at bar.””
