Opinion

WALLACE, District Judge.

The plaintiff, Hughes Tool Company, a Delaware corporation, brings this action against the defendant, R. W. Ford, a resident of Ada, Oklahoma, to:

(1) Enjoin the defendant from future infringement and to recover damages for past infringement of plaintiff’s Letters Patent No. 1,856,627, No. 1,983,316 and No. 2,333,746 relating to roller rock bits used in drilling for oil and gas.

(2) Enjoin the defendant from acts of trespass upon and conversion of and to recover damages for past trespasses and conversions of plaintiff’s drill bits.

(3) Enjoin the defendant from further interference with and to recover damages for past interference with the plaintiff’s lease agreements, whereby the plaintiff leases, rather than sells, the drill bits which it manufactures.

The defendant admits certain acts of welding on the worn cutter teeth of bits of various series of plaintiff’s manufacturer but expressly denies that such acts constituted an infringement of lawfully issued patents.

The defendant counterclaims alleging in substance that the plaintiff corporation has used its “lease” agreement as part of a plan to dominate and control the roller rock bit industry and charges that the plaintiff corporation is operating in violation of the antitrust statutes. Defendant in his counterclaim requests the Court to find the plaintiff to be in violation of the antitrust laws, to decree that the patents and the “lease” contract here involved to be unenforceable, to enjoin any future monopolistic practices by the plaintiff, and to decree an accounting for the purpose of determining the damage done to this defendant for the purpose of awarding relief in accordance with Section 4 of the Clayton Act, 15 U.S.C.A. § 15.

The evidence introduced at the time of trial of these issues consisted of oral testimony, testimony given in discovery depositions, the records of testimony given in former cases introduced upon stipulation of counsel, and a large number of exhibits.

I

The plaintiff is the owner of Fletcher Patent No. 1,856,627, Scott and Garfield Patent No. 1,983,316, and the Scott, Garfield and Cockrum Patent No. 2,333,746 and in this action sues for past infringement.

The validity of Patent No. 1,856,627 and Patent No. 1,983,316 was not attacked by the defendant.

The defendant admittedly retipped 1 partially worn down teeth of drill bits of plaintiff’s manufacture made in accordance with Patent No. 1,856,627 and Patent No. 1,-983.316. However, defendant argues that inasmuch as he merely retipped partially worn down teeth of drill bits made in accordance with Patent No. 1,856,627 and merely retipped partially worn down teeth, that were still interfitting, on drill bits made in accordance with Patent No. 1,-983.316, that such acts did not constitute an infringement of these two letters patent, but were only permissible repair.

Such a contention is foreclosed by the ruling in the first Williams case which involved retipping in regard to these same two patents. In his opinion Chief Judge Phillips said: 2

“Williams, by his process of retipping, undertakes to restore the worn-out teeth as *529 nearly as possible to their original form, size, and position. He thus reconstructs and replaces that element of each patent wherein lies the novel features of the combination. We hold that so doing is not permissible repair, but reconstruction, constituting infringement. This conclusion finds support in Hughes Tool Co. v. Owen, 5 Cir., 123 F.2d 950, in Southwestern Tool Co. v. Hughes Tool Co., 10 Cir., 98 F.2d 42, 45; American Cotton Tie Co. v. Simmons, 106 U.S. 89, 1 S.Ct. 52, 27 L.Ed. 79, and Hughes Tool Co. v. United Machine Company, D.C.N.D.Tex., 35 F.Supp 879.”

Thus, any such acts of retipping by the defendant prior to the expiration dates of these patents constituted an infringement. 3

The defendant vigorously contests the validity of “Patent No. 3” in suit, the Scott et al. Patent No. 2,333,746, referred to as the “interrupted heel tooth patent.” 4

The plaintiff alleges infringement of claims 1 and 4. 5

Claim 1 provides:

“In a well drill, a tapered cutter rotably mounted thereon, said cutter having a row of heel teeth circumferentially thereof to cut the outer portion of the well bottom, some of the teeth in said row having a portion pro-j ecting from the cutter surface a shorter height than the others, thus providing on said shorter teeth an open area normally out of contact with the well bottom so as to allow cleaning of the cutter by the flushing fluid, and a gage cutting surface on the outer ends of all said teeth to engage the wall of the well.”

Claim 4 provides:

“In a well drill, an inwardly tapering cutter having a row of teeth circumferentially around the same, the outer ends of which are positioned to cut the side wall of the hole, there being crests on said teeth positioned to engage the bottom of the well, the crests on some of said teeth being comparatively short and extending from the inner ends of said teeth approximately one-half of the length of the tooth, there being formation receiving spaces at the outer ends of said short crested teeth some of said teeth being spaced more closely together in the row to throw the teeth out of step on bottom.”

Counsel for plaintiff in making a preliminary statement regarding the object of this patent said: 6

“Also Hughes Tool Company wanted to increase the speed in those formations [sticky formations], clean them better, and then they did what was really, well really it was a crazy sort of thing, having new teeth on the cutter, going to the trouble of making the invention, in order to accomplish it they then cut them off, or part of them. The witness can give more explanation of it, but in the heel row now, they take, in this illustration, it’s every alternative two and they cut away the outer end of that tooth crest. See, the way that’s cut away as shown here on this bit, so they cut away alternative ends of the teeth in the heel row. The patent points out that there can be variations as how that is done.
“Well now, what was the result? Certainly no one had ever thought of doing it before. Actually, just cutting away part of those two crests, they got a very material increase in speed in these formations, the drilling was faster. Another curious thing in instances they would stay in the hole-longer, actually have less teeth, they’d get more footage out of it, and while this is not as pronounced, perhaps, as the increase in speed in those formations, there was a very pronounced increase in speed.”

An aim of the patented invention is to generally preserve the spacing of such rock *530
