Opinion:
EACOMBE, Circuit Judge.
The questions involved in this appeal have been several times judicially determined adversely to defendant.
There is no serious contention that defendant's device is substantially different from the devices found to be infringements in the earlier cases.
The patent was first held valid and infringed by Judge Cross, sitting in the district of New Jersey. Johns-Pratt Co. v. Freeman (D. C.) 201 Fed. 356. His decision was affirmed by the Circuit Court of Appeals, for the Third Circuit, 204 Fed. 288, 122 C. C. A. 512. Subsequently a motion for preliminary injunction, after a long argument, was granted by Judge Thompson in the Eastern District of Pennsylvania, the defendant being the Economy Fuse Company; no written opinion was filed. Infringement was also found in the case of Johns-Pratt Co. v. Sachs Co., decided in this court (175 Fed. 70, 99 C. C. A. 92); the validity of the patent was not there passed upon, as defendant was in privity with the inventor who could not be heard to assert its invalidity. The patent, prior art, etc., were very fully considered in the opinions in the Freeman Case.
There is no prior art in this record which was not before the Circuit Court of Appeals in the Third Circuit, except possibly the Downes patent, 640,371. That patent was discussed by the court, but it assumed that it was later than Sachs. It now appears that the application for the Downes patent antedated Sachs'. That circumstance, however, is unimportant because Downes shows, not only a plurality of small wires or strips instead of Sachs' thin flat strip of extended area, but also an "air space about the middle of the fuse-link," which Sachs eliminates by entirely filling the containing box with nonconducting material.
We concur with the judges in the Third Circuit and with Judge Hazel in the conclusion that no one .prior to the patentee had combined in one structure the thin flat strip of metal, of extended area, embedded within and entirely isolated by a filling material, which was in contact with a maximum amount of surface of the strip as a result of its thinness and wideness and which strip was connected to terminals of greater conductivity within the case which held the filling material about the strip. It seems unnecessary to add anything to the discussion of the case? in the Third Circuit and in the later opinion of Judge Hazel in the case now on appeal.
The decree is affirmed, with costs.
