    It is immaterial whether the patentee had notice of the prior invention or not. If it was in actual use in any part of the world, however unlikely or impossible that the fact could come to the knowledge of the patentee, his patent for the same machine cannot be supported.

  2. whether a use is public or private is not a question of constitutional construction. It is a question of general law. It has as much reference to the constitution of any other State as it has to the State of Wisconsin. Its solution must be sought not in the decisions of any single State tribunal, but in general principles common to all courts.

  3. Whether the use of a railroad is a public or a private one depends in no measure upon the question who constructed it or who owns it. It has never been considered a matter of any importance that the road was built by the agency of a private corporation. No matter who is the agent, the function performed is that of the State. Though the ownership is private the use is public.

  5. A spur may, at the outset, lead only to a single industry or establishment; it may be constructed to furnish an outlet for the products of a particular plant; its cost may be defrayed by those in special need of its service at the time. But none the less, by virtue of the conditions under which it is provided, the spur may constitute at all times a part of the transportation facilities of the carrier which are operated under the obligations of public service, and are subject to the regulation of public authority. ... The uses for which the track was desired are not the less public because the motive which dictated its location over this particular land was to reach a private industry, or because the proprietors of that industry contributed in any way to the cost.

  6. To gather the streams from waste and to draw from them energy, labor without brains, and so to save mankind from toil that it can be spared, is to supply what, next to intellect, is the very foundation of all our achievements and all our welfare. If that purpose is not public, we should be at a loss to say what is. The inadequacy of use by the general public as a universal test is established.

  7. A mere experimental use is not the public use defined by the Act, but a single use for profit, not purposely hidden, is such. The ordinary use of a machine or the practise of a process in a factory in the usual course of producing articles for commercial purposes is a public use.
