Facts

This case involves a petition for rehearing regarding the infringement of reissued letters patent No. 4372, granted to Nelson W. Green for an improvement in constructing artesian wells. The original patent was granted in 1868, and the application was filed in 1866. The circuit court dismissed the bill, ruling the patent invalid due to prior public use of the invention more than two years before the patent application. The appellants argued that this prior use was without Green's knowledge or consent, while the appellee contended that such consent was not necessary to invalidate the patent.

Issue

Whether the patent was invalid due to prior public use of the invention more than two years before the application for the patent, regardless of the patentee's knowledge or consent.

Whether the patent was invalid due to prior public use of the invention more than two years before the application for the patent, regardless of the patentee's knowledge or consent.

Rule

Analysis

The court analyzed the facts surrounding the public use of the invention, determining that the invention had indeed been used by others more than two years before Green's application. The court emphasized that the relevant statute does not require the patentee's consent for prior use to invalidate the patent. The appellants' argument regarding the necessity of consent was found to be unsupported by the statute's language.
