Béné v. Jeantet

Syllabus

<p>The reissued' letters' patent No. 8637, granted to John Béné March 25, 1879, for an improvement in the process of refining and bleaching hair, is limited to the second claim and is to- be construed as a patent for a' process 'of refining hair by treating it in a bath composed of a solution of chlorine salt dissolved in an excess of muriatic acid; but within that limit it is a pioneer invention and is entitled to receive a liberal construction.</p> <p>The testimony of two experts in a patent suit being conflicting, and the evidence of one being to facts within his knowledge which tended to show that there was no infringement, while that of the other, who was called to establish an infringement, was largely the assertion of a theory, and the presentation of arguments to show that facts testified to by the other could not exist; Held, that no case of infringement was made out.</p>
