The on-sale bar is an extraordinarily (some would argue needlessly) complex body of patent law in all but the simplest cases.

The patent owners were asked how much effort was required to produce their inventions and how much monetary value their patents had been worth. The median effort to create the patentable invention was 1 person-year, with 10% of the patent owners requiring 2 or more person-years.
Egbert v. Lippmann, 104 U.S. 333 (1881), was a case in which the Supreme Court of the United States held that public use of an invention bars the patenting of it.
