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 11 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““But the specification authorizes a claim for the process of sulphonating rosaniline with fuming sulphuric acid in given proportions, without regard to the anhydrous condition of the'rosaniline or the density of the sulphuric acid employed, and the terms of the process claim are commensurate with such a process. The process claim must therefore be construed as embracing the conversion of the rosaniline by means of fuming sulphuric acid, without respect to the anhydrous condition of the rosaniline, or the peculiar strength of the fuming acid. Thus1 construed, the process claim is void for want of noyelty. The art of sulphonating dyestuffs by combining them with the elements of sulphuric acid, and converting them into sulpho-aeids, is very old. The proofs show that prior to the date of the invention of Holliday it was well known in the art that, owing to the character of nnsnlphonated indigo, the coloring matter thereof could not he employed, either alone or mixed with other coloring matters, where the process of dyeing or printing required the employment of an acid or acid mordant; and that the indigo, by being snlphonated, could bo converted into new coloring matter, possessing acid properties, and retaining substantially its original color when used in an acid bath. The proofs also show that the process for sulphonating indigo was substantially the same as the process of the Holliday patent, disregarding the reference to the degrees Beaume; and the treatment of the rosanilin”
