Dyson v. Gambrill
Opinion of the Court
When this case was before me, in September, 1860, on the ex parte application of Mr. Dyson for the reissue of his patent of the 20th February, IS 19, so as to embrace in the reissue the differential motion of the stripper to his carding machine [see Ex parte Dyson, Case No. 4,228] I said in my opinion of the 21st September, 1800, at page six of the printed copy: “It is said the office may be deceived, and made the innocent instrument of deception by granting patents for the like invention to subsequent claimants. When this is so, the office, has only to declare one interference, and the truth can be brought out. At all events, the subsequent patentee can then bring his adversary face to face, and cross-examine his witness, and offer evidence on’his own part,” &e. And again, at page ten of the same printed opinion, I say: “If there be no claimant, or subsequent unexpired patent, for the same invention claimed on this reissue by Mr. Dyson, then I think Jeptha Dyson, the appellant, is entitled, on the proof, to his reissue as claimed by him; but, if there be such claimant, or subsequent unexpired patent, then I think an interference ought to be declared, and the parties litigant, heard on proof before the office.” After the return of my opinion and judgment of the 21st September, 1S00, to the office, it seems an interference v’as declared between Mr. Dyson, on his reissue claim and the unexpired patent of Gambrill and Burgee of the 27th February, 1S55, and reissued November 17th, 1S57. The principle of the improvement embraced in these interfering claims is doubtless the same, and the office, conforming to my decision, rightly declared the interference.
The four witnesses on whose ex parte evidence I relied in my opinion of the 21st September last on Dyson’s ex parte application for reissue have not been examined on the present interference. Gambrill and Burgee have had no opportunity to cross-examine them, — a right asserted by me in my former opinion, at page six, to belong to them. This evidence therefore is not in the present interference, and cannot be looked at or regarded by me now, and is so admitted by
So in this case my duty is to inquire into all the circumstances, which invalidate Mr. Dyson’s claim to the reissue asked for by him. It is not sufficient for Mr. Dyson to prove that he invented the improvement before Gambrill and Burgee. To get his reissue, he must prove the invention to have ■been made by him before the date of his •original patent, the 20th February, 1849. I must therefore overrule the appellant's 2nd •and 5th reasons of appeal, and I do, this 9th day of July. 1801, affirm the decision of the commissioner of patents of date 19th .March. 1861, refusing Mr. Dyson a reissue patent, as claimed, for the reasons above stated by me. I return herewith all the papers, models, and drawings with this, my opinion and judgment, this 9th day July, 1SG1.
