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.
““If the appellee had been more interested in promoting or exploiting its patent than in selling its Tret-O-Lite it would have been a very simple matter to fix a royalty fee of so many cents per gallon whether purchased from the appellee or from outsiders. Indeed, no other course on the part of a pat-entee who is selling a commercial product to use in the patented process he owns would seem to quite meet the claim that the practice of combining the price of a royalty and of the product in the same unit without separation tends to promote a monopoly in the product if the patent monopoly is not waived.””
