141 F. 378 | S.D.N.Y. | 1905
The patent is only %y2 years old, and has not been adjudicated. That circumstance alone, however, is not enough to overcome the presumption of validity arising from issue by the Patent Office. It must also appear that from common knowledge, or by reason of some display of the prior art, there is reasonable ground for doubting the existence of patentable novelty. Fuller v. Gilmore (C. C.) 121 Fed. 129; Lambert v. Vibrator Co. (C. C.) 138 Fed. 82.
In addition to the device first described, the patentee on page 2, lines 27 to 68 of the specification, sets forth a modified form of his bolt anchor. It is so arranged that the interior corrugations are interrupted, and interrupted in such a manner that at intervals two or more of. the corrugations engage with the threads of the screw; the threads being left free in the spaces between. And these intervals of engaging corrugations are so spaced that screws having threads of different pitch may be used with the same anchor bolt. This is possible, because all screws are made with a definite number of threads to the inch. In none of the prior patents is there the slightest indication of any such interior arrangement accomplishing such a result. In the patent which is relied upon as the best reference (Loffehardt, 665,536)the dowel pins, which may be considered to be the equivalents of interior corrugations, are shown as engaging each alternate thread, and it is apparent that they are not adapted for use with screws of varying pitch. If Loffehardt’s dowels were located at intervals of an inch apart, a different question would be presented. The suggestion of a mode of insuring general adaptability would have been made, and Newton’s device with greater engaging surface might be considered a mere improvement to be narrowly construed. But upon the showing of the art here presented Newton’s device is entirely novel, it certainly is useful, and so far as appears exhibits patentable invention. The eighth claim fully and clearly covers this “modified form” of bolt anchor.
Upon giving a bond in the amount of $1,000, conditioned that in the ■ event of defendant’s success at final hearing complainant will pay all damages resulting from the operation of preliminary injunction, complainant may have such injunction as prayed. The injunction, however, will be suspended for 30 days to give defendant opportunity to review this decision. The record is so brief that appeal can be perfected and record printed within ten days; and, since the rules give preference to such an appeal, it can be heard at December session of the court of appeals.
