This cause has been before hoard and considered. Hayes v. Bickelhoupt, 21 Fed. Rep. 567. A rehearing has been granted and had as to the second claim of reissue 8,675, the second and third claims of 8,688, and the second and third claims of 8,689, on account of mistake of models of patent for those relied upon to show infringement, and of error in reference to former decisions upon the same patents. It was said by Judge Benedict, in Hayes v. Seton, 12 Fed. Rep. 120, that the second claim of 8,675 appeared to be for the same invention described in the original patent. He states no comparison of this claim of the reissue with those of the original. Its basis must be the first claim of the original. That is for an arrangement and this for a combination of parts. There are parts in each not mentioned in the other. They may be said to appear to be the same, by considering the parts specified in the claim of the reissue, and not mentioned in the claim of the original, as implied from the specification of the original into the claim, by the words, “as specified,” in the claim. What is said there as to infringement of this claim indicates this construction. A moulding secured by rivets, bolts, etc., to form a brace, is one of the elements of the combination of the reissue not specified as such in the arrangement of the original. The alleged infringement did not have that, and it was held not to be an infringement. The alleged infringement here does not appear to have that, and does not appear to be an infringement. Construed to cover the infringement, the reissue would depart from the original, and constructed to follow the original it does not appear to be infringed.
Claim 2 of 8,688 appears to be identical with claim 1 of the original, and has once been held valid, in view of the alleged anticipating devices. Hayes v. Bockel, 11 Fed. Rep. 87. It was held not to be infringed because the gutters were not under cover of the bases which supported the glass in Hayes v. Seton, supra, and Hayes v. Dayton, 20 Fed. Rep. 690. Here the alleged infringement has the
It is urged that infringement has not been properly proved because no expert has been called to show and explain how the defendant’s structures infringe the different claims of the patents, and many cases in which it is held that infringement must be proved have been cited. There can be no question but that infringement, if not admitted, must be proved by competent evidence. There does not appear to be any prescribed method of proof by experts, however. Explanations of matters not commonly or readily understood may be necessary, but when it is proved that the defendant has done what is plainly an infringement, further proof to establish the fact would not seem to be necessary. It is urged that the bill should be dismissed because it set forth that all the claims of all the patents were infringed in one structure to avoid multifariousness, and that this was denied in the answer and shown to be untrue by the proofs. But all the claims held to be valid and to be infringed are infringed by one structure, the Sherwood studio building, therefore this position is not tenable. The orator appears to be entitled to a decree that claims 2 and 3 of 8,688, and claim 3 of 8,689, are valid and have been infringed by the defendant, but not to costs, because he prevails on account of a dis
Let there bo a decree for the orator for an injunction and an account, without costs, accordingly.
