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 696 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“* * * A process is reduced to practice when it is successfully performed.”
17 later decisions quote this exact passage · from the majority““It is a mistake to assume that reduction to use must necessarily be a commercial use. If Kratz discovered and completed, as we are convinced that he did, the first use of D. P. G. as an accelerator in making vulcanized rubber, he does not lose his right to use this discovery when he chooses to do so, for scientific purposes or purposes of publication, because he does not subsequently sell the rubber thus vulcanized, or use his discovery in trade, or does not apply for a patent for it. It is not an abandoned experiment because he confines his use of the rubber thus produced to his laboratory or to his lecture room. It is doubtless true that Kratz, by his course in respect to his discovery as to the use of D. P. G., has abandoned any claim as against the public for a patent, but that is a very different thing from saying that it was abandoned as against a subsequent discoverer or patentee.””
3 later decisions quote this exact passage · from the majority““A ‘cure’ is the successful completion of the chemical union or vulcanization of the rubber with the sulphur. The fact of a successful ‘cure’ for practical purposes is established by a simple and short method called the thumb and tooth test. By this test, rubber chemists settle the fact and determine by the resulting product the satisfactory quality of the stock or the mix for vulcanization and they become expert at it. If by this test the product is not well united chemically, it is said to be ‘under cured’ or ‘over cured,’ and then the operator changes the ingredients or the time of the process. When it is important to determine with greater exactness the tensile strength and degree of elasticity or other, qualities of the product, a special machine measure or test is used, but the thumb and tooth test is the frequent way of knowing a cure, and it is a satisfactory one for everyday use in business,””
