David Josiah Brewer,
United States v. American Bell Telephone Company…
“ So the government may well insist that it has higher rights in a suit to set aside a patent for land than it has in a suit to set aside a patent for an invention. There are weightier reasons why the government should not be permanently deprived of its property, through fraudulent representations or other wrongful means, than there are for questioning the validity of a temporary monopoly or depriving an individual of the exclusive use for a limited time of that whose actual use he claims to have made possible, and which, after such time, will be open and free to all. ”
