Bellows v. United Electrical Mfg. Co.
Opinion of the Court
Claims 11, 12, 13, 16, 18, 19, 21, 23, 25, 26, 27, and 28 of the patent mentioned are in suit. Complainant charges infringement by the manufacture, use, and sale of certain telegraph keys invented by one Martin. Specimens of Martin’s keys are marked “Complainant’s Exhibit, Defendants’ Key,” and “Defendants’ Exhibit, Defendants’ Key.” Two questions are involved: First, the validity of the patent in suit; and, second, if valid, are the claims in issue infringed ?
I do not think, in view of the prior art, the patent in suit can be so broadly construed as to embrace or cover defendants’ key. If so broadly construed, the claims in suit cover keys of a prior patent to Martin, No. 732,648, and are invalid, because anticipated, and Coffee was not the first inventor.
There will be a decree dismissing the bill of complaint, with costs.
