How has the statute of limitations been interpreted in the history of patent litigation?

Campbell v. City of Haverhill, 1895, 155 U.S. 610, 15 S.Ct. 217, 39 L.Ed. 280, which dealt with problems arising from the lack of a limitations period in federal statutes concerning patents, laid down the guide that the state statute of limitations applicable to the federal right was that applicable to state actions of a similar nature.

We have been cited to no Oregon law which controls on the limitations problem. Our research develops Shelton v. Paris, 1953, 199 Or. 365, 261 P.2d 856, 858, which may assist with its definition of a "liability created by statute."
