16 F. Supp. 115 | D. Del. | 1936
Motion to dismiss the supplemental bill of complaint as amended.
The grounds of the motion are that the Smith reissue letters patent No. 19,010 is prima facie invalid because of laches in thirteen years’ delay in applying therefor, and, further, that the supplemental bill of complaint as amended fails to set forth specific facts and circumstances justifying such delay.
A brief reference to the reissue statutes is illuminating. In the early days of our patent system the presence of one invalid claim in an original patent vitiated the whole patent. The act of 1832 (Act July 3, 1832, 4 Stat. 559) provided a remedy for reissue without penalty. The act of 1836 (Act July 4, 1836, 5 Stat. 117) provided a remedy by reissue where the patentee had claimed too much. Under this act two penalties were imposed if a patentee took a reissue: (1) A re-examination by the
The Smith reissue patent is not a broadened reissue. The new claims added by the reissue are all specifically narrower than the claims of the original patent. The rules of law with respect to the diligence required in filing applications for reissues differ as between broadened reissues and reissues in which the new claims are not broader but narrower. The “two year rule” applicable to broadened reissues does not apply to reissues in which the new claims are narrower than the claims of the original patent. In the case of a broadened reissue, the reissue expands the field covered by the patent beyond that which the claims of the original patent have indicated as the patentee’s exclusive field. If such expansion is to be permitted, prompt action on the part of the patentee should be required. In the case of a reissue in which the new claims are not broader but are narrower, there is no expansion beyond the field pre-empted by the original patenc. The same promptness of action required in the case of a broadened reissue is not necessary. In the case of narrower, as distinguished from broader, reissues, reasonable diligence is required after discovery of the defect in the original patent. Where there have been no facts or circumstances to bring the defect to the notice of the patentee or owner, his delay in discovering the defect may have continued without charging him with any lack of diligence and without affecting the validity of the reissue.
The amended supplemental bill avers: The original Smith patent was issued July 20, 1920. It was acquired by plaintiff November 12, 1932. The defect in the claims of the original patent was not discovered by or known to any of the prior owners. No use was made of the patent and no defect was discovered. These averments are sufficient to negative laches or unreasonable delay prior to November 12, 1932. It is further averred: Promptly upon the acquisition of the patent, the plaintiff caused the question of the adequacy of the specification and claims to be reviewed by a patent attorney and the defect still remained undiscovered until May 31, 1933, and plaintiff cannot be charged with any negligence or lack of diligence prior thereto. From May 31, 1933, when the defect was first discovered until the actual filing of the reissue application in October, 1933, a period of approximately four months, the owner of the patent was diligently engaged in the steps necessary to prepare the reissue application. The averment is that these steps were taken with all reasonable dispatch.
The averments of the supplemental bill as amended are sufficient to repel any inference of laches arising from delay. In view of these averments, it cannot be held as matter of law that there was inexcusable delay.
The invalidity of the patent on the ground of delay in applying for reissue affects only the new reissue claims. The invalidity of such claims on the ground of delay has no effect whatever on the claims carried over into the reissue identical in form with those in the original patent. In a Supreme Court case new claims added by reissue were held invalid on the ground of delay, but the court specifically held that the patent was valid so far as concerns a claim carried over into the reissue from
The motion to dismiss must be denied.
