Opinion

TUTTLE, District Judge.

This suit involves reissue patent No. 16,817 issued December 13, 1927, on an application of J. H. Smith; the original application was filed September 20, 1920. No question is here raised as to the propriety of the reissue, and it is therefore held that the reissue is a valid one if the claims state subjeet-matter patentable over the prior art. No question of infringement is involved, and the case turns solely on the validity of the claims of the reissue patent.

The patented claims are drawn to a boring tool having a head and cutters of more than one diameter with cutting ribs of the smaller diameter running substantially the entire length of the head and cutting ribs of larger diameter starting at a point somewhat removed from the working end of the head and running substantially the rest of the length of the head in overlapped relation with the cutters of smaller diameter. The testimony shows that Mr. Smith designed the patented tool as an improvement over the old stepped eounterbore; that is, a tool in which the several diameters were all located on the same cutting rib. This old stepped eounterbore is capable of enlarging an already present hole to two or more diameters, or enlarging the hole and performing facing operations. However, when the old tool is ground back in sharpening, ordinarily the life of the tool will be no greater than the shortest distance between two diameters. The reason for this is that in grinding back the portions of ribs of larger diameter, the grinding nicks into what becomes the rib parts of smaller diameter.

Smith made a very decided improvement over this stepped counterbore. The tool, instead of being so limited in its life, can be ground back to substantially the full length of the shortest cutting rib. This rib may be made of considerable length, and consequently the life of the tool is very much greater, for each diameter has an entirely independent rib. Furthermore, the ribs can be sharpened with less difficulty because they are independent. Again, other advantages flow from the independence of the ribs, especially in conducting away heat generated in the cutting operations. This independence for each cutting rib of different diameter has also made possible quite a high development in this tool in the way of multiple cutting operations by a single cutter. It has made it possible to perform a number of simultaneous facing, boring, and chamfering operations, all with one tool, and in which the working edges of the separate ribs are closely grouped when considering their relative location along the length of the tool. This would not be commercially practical in the old stepped counterbore, for the reason that the life of the tool would be so short, due to the dose grouping of these cutting edges on one blade, that its use would result in a very high tool expense.

Approaching the issues here involved from this angle of the case as presented by the plaintiff’s proofs, the patented invention indicates decided genius and decided worth. I find a decided improvement also over the multiple diameter tool with removable blades.

The defense centers chiefly around a prior use of a tool by the Ohio Brass Company, at Mansfield, Ohio, and the Thomas patent, No. 805,170. This prior use at Mansfield, according to the accepted doctrine, must be proved beyond a reasonable doubt. Fur[943]*943thermore, the proofs must satisfy the court that this tool was used by the Ohio Brass Company with some degree of success.

The court has read the depositions taken at Mansfield, and has also listened to what counsel have had to' say about these depositions, letting them point out any portions on which they rely. There has been testimony here in open court of one witness who testified that he was with the Ohio Brass Company at Mansfield during the period involved, and that many years before the patent in suit the drawings here in evidence were made, and that one tool that I have seen was made, and that the tools were used.

Now I have no doubt whatever about the genuineness of these drawings. I have given careful consideration to the attack made on them, but I am convinced that the drawings are genuine and that there is not fraud or perjury in connection therewith. I find there is record proof here of the drawings and the time they were made, tracing it back from the inventory sheet made in 1920, listing the tool by number. This identifies it with the drawings and it is listed as a tool made in 1913. Using the best judgment I have in the way of testing what is safe to rely upon and what is not safe, recognizing fully that I ought not to use this at all unless I am satisfied beyond a reasonable doubt that it is genuine, I have no reasonable doubt at all, and I must say, in performing my duty, that I have no reason to doubt but what they made the drawings back in 1913 — or about that time, the exact date is not important, because it is so many years before the patent in suit that we are not confronted with any nicety of hours, or days, or weeks, or months, but a period of years intervening. One of those old tools made from that drawing is here in court as an exhibit, to wit, Exhibit 1.

Of course, it is possible for anybody to be mistaken, but as to the fact that those drawings were made at the time alleged, and the tools were made and used, and that this is one of them, seems to me about as near positive as anything can be in the way of proof about events that happened long ago.

The degree of success of this Mansfield tool is not so plain. I am satisfied that the tool made at Mansfield was not anywhere near as sueessful as the present tool of the plaintiff, but I do not understand that that is the test, measuring its success by the present success and present usefulness. I am satisfied that they made it and that they used it. It was an operative tool, and I think therefore it comes into this lawsuit and must be dealt with as part of the prior art.

This is one of those eases where the patentee knew nothing about the prior use, and the court can hardly help feeling sorry that there actually was this prior use. It did not help the applicant at all. What was done at Mansfield was not published, was not patented, and the amount that it helped the world, of course, was pretty limited. But so long as I find, as I do, beyond a reasonable doubt, that it was done, that it was used, and with mechanical success sufficient to bring it into the art, I am forced to consider it. I say almost reluctantly that I reach this conclusion, but that is part of the patent game. Every man who makes an invention undoubtedly retravels roads that have been traveled by somebody else; he has never seen the scenery, and it is new to him. He does just as much work as if the other man had not blazed the trail at all. This is one of the injustices of the law that cannot be cured, and necessarily so, and any attempt to cure it would be attended with greater misfortunes than the one I have pointed out.

The Thomas patent in a way belongs to the same category, but of course the patentee might have found the Thomas patent upon a search. The Mansfield tool clearly recognized the advantage of getting away from the stepped tool. It recognized the desirability and advantage of having cutting blades entirely separate and distinct, so that they could be ground. It carried with it also the advantage of saving the tool from overheating, which I think is considerable, for this tool had a greater body of metal to carry away the heat than the edge that was doing the cutting.
