211 F. 473 | N.D. Ohio | 1913
This case is a suit charging infringement of the Niesz reissue patent, No. 13,163, of November 1, 1910, relating to disc harrows. The Niesz patent was issued to the Bucher & Gibbs Plow Company, the complainant herein, as the assignee of Prank B. Niesz, the inventor. Original patent No. 916,361, of which the patent in suit is a reissue, was dated March 23, 1909, and the application for the reissue was filed July 19, 1910. The original and reissued patents a.re for the same invention and both for a new type of harrow. The new patent was issued under the provision of Revised Statutes, § 4916 (U. S. Comp. St. 1901, p. 3393), and chiefly for the reason that the claim of the original patent was defective, incomplete, and insufficient for the purpose of protecting the invention disclosed and described in the original patent. Complainant commenced the manufacture and sale of the device in controversy in August, 1908, and by June, 1909, had sold 678 harrows. In May, 1909, the defendant purchased one of •the complainant’s harrows, involving the claims of the invention here in controversy.
The reissue patent contains six claims, but the fourth claim is perhaps the broadest. It provides:
“(4) In a harrow, the combination, with a front harrow frame, and adjustable disc shafts carried thereby, of a rear harrow frame flexibly connected at its front end to .the front frame at the point between the ends of the front frame, separate disc frames vertically pivotally connected to the rear frame, means adjustably turning the frames on their vertical pivots, and horizontal slidable engaging members between the disc frames and the rear frames to prevent a tilting movement of .the disc frames.”
The defendant contends that the invention sought to be protected by the reissue patent was a different invention from that covered by the
. As bearing upon the prior art, defendant has set up seventeen patents. Nine of them, Galt & Tracy (two), Nauman, Little, La Dow, Sharp (two), Lingren, and Wildman, consist of a single disc harrow. Five of these patents, Wilson, La Dow 388,567, Wright, Clark 712,996, and McVicar, are for a rigid double-disc harrow. It is quite probable that by combining various of these patents, and by making certain changes, removing certain parts, or reorganizing some of the parts which are found in these various patents, the structure claims by the Niesz patents can be built up. It is argued that Niesz had before him these prior structures, disclosed by these patents, and that the combining of these structures into the harrow of the Niesz invention was an obvious thing to do; that any mechanic would do it. It does seem simple, yet nevertheless it never was done before, and the novel combination of Niesz’s evidently presented great utility, as shown by the adoption of this device by the defendant company.
The five patents showing efforts in the double-disc harrow field fail to disclose the combination and arrangement of parts which are the subject-matter of the Niesz patent in suit, which combination has undeniable advantages. It is important to determine whether the proper foundation for the granting of the reissue patent has been laid.
The claim of the original Niesz patent is:
“In a disc barrow the combination of a front and rear disc frame, the rear disc frame consisting of parallel bars journaled intermediate their ends and a connecting bar, a head secured to said connecting bar and spaced plates secured to the head and means for rocking the rear disc frames upon their pivoted points, substantially as and for the purpose specified.”
The structure of the defendant is' practically a copy of the structure made by the complainant, with the .exception that the anti-tilting devices are different in form and the manner of location, but perform ■ substantially the same functions.
The defendant, being in possession of these facts, cannot well claim an estoppel against the reissue patent. No intervening rights accrued .to the defendant in this case upon which, in equity, it can rely. The
“From this summary of the authorities it may be regarded as the settled rule of this court that the power to reissue may be exercised when the patent is inoperative by reason of the fact that the specification, as originally drawn, was defective or insufficient, or the claims were narrower than the actual invention of the patentee, provided the error has arisen by inadvertence or mistake, and the patentee is guilty of no fraud or deception; but that such reissues are subject to the following qualifications: First. That it shall be for the same invention as the original patent, as' such invention appears from the specification and claims of such original. Second. That due diligence must be exercised in discovering the mistake in the original patent, and that, if it be sought for the purpose of enlarging the claim, the lapse of two years will ordinarily, though not always,” be held as abandonment “to the public to the same extent that a failure by the inventor to apply for a patent within two years from the public use or sale of his invention is regarded by the statute as conclusive evidence of an abandonment of the patent to the public. Third. That this court will not review the decisions of the commissioner upon the question of inadvertence, accident, or mistake, unless the matter is manifest from the record; but that the question whether the application was made within a reasonable time is in most, if not all, such cases a question of law for the court.
“To hold that a patent can never be reissued for an enlarged claim would be not only to override the intent of the statute, but would operate in many cases with great hardship upon the patentee. The specification and claims of a patent, particularly if the invention be at all complicated, constitute one of the most difficult legal instruments to draw with accuracy, and, in view of the fact, that valuable inventions are often placed in the hands of inexperienced persons to prepare such specifications and claims, it is no matter of surprise that the latter frequently fail to describe with requisite certainty the exact invention of the patentee, ah error either in claiming that which the patentee had not in fact invented, or in omitting some element which was a valuable or essential part of his actual invention. Under such circumstances, it would be manifestly unjust to deny him the benefit of a" reissue to secure to him his actual invention, provided it is evident that there has been a mistake, and he has been guilty of no want of reasonable diligence in discovering it, and no third persons have in the meantime acquired the right to manufacture or sell what he had failed to claim. The object of the patent law is to secure to inventors a monopoly of what they have actually invented or discovered, and it ought not to be defeated by a too strict and technical adherence to the letter of the statute, or by * * * artificial rules of interpretation.”
I accordingly reach the conclusion that the Niesz reissue patent is for a novel combination of elements, evidencing a new type of double-disc harrow; that the defendant’s structure is an infringement of the reissue patent; that the reissue patent is for the same invention as that described and claimed in the original patent; that the original patent was defective and.insufficient with reference to its single claim; that the defendant’s structure includes all of the elements of the insufficient claim of the original patent; that the defendant cannot utilize the doctrine of equitable estoppel or intervening rights.
A decree may be drawn in favor of the complainant.
