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 10 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““Nor does the question, whether the use of an invention is public or private, depend upon the number of times it is used, or upon the number of persons to whom its use is known. If an inventor, having made his device or design, gives or sells it to another without restriction for use by him or injunction of secrecy, and it is so used, such use is public, even though it, and knowledge of it, may be confined to one person. We further recognize that the use may be public, although concealed by the nature of the invention itself; and, further, that the use of a single specimen, even in a factory and in the presence only of the employees may be public.” [Emphasis supplied.]”
