Opinion

SAVAGE, Chief Judge.

Findings of Fact

From the evidence adduced at the trial’ of the above entitled cause, the Court finds the following facts:

Jurisdiction

1.

Each Plaintiff is a corporation of the-State of California. Defendant Oscar E_ Dempsey is a citizen and resident of Oklahoma. Defendant Dempsey Pump Company is a corporation of the State of Oklahoma. Defendant Specialty Sales and Service, Inc. is a corporation of the State of Oklahoma. Defendant M. L. Walraven,, Jr. is a citizen and resident of Oklahoma.

2.

The first cause of action asserted by-Plaintiffs arises under the laws of the-United States relating to patents and claims for infringement thereof; and the- *343 •second cause of action asserted by Plaintiffs is wholly between the citizens of •different states in which the amount in controversy exceeds $3,000.00 exclusive of interest and costs.

3.

The several counterclaims of the Defendants Dempsey Pump Company and Specialty Sales and Service, Inc. arise out of the transaction or transactions which are the subject matter of the causes of action asserted by Plaintiffs; and said counterclaims further arise under the laws of the United States relating to trusts, monopolies and restraints of trade, and to declaratory judgments; and said counterclaims further are controversies wholly between citizens of different states in each of which is involved a sum or value in excess of $3,000.00 exclusive of interest and costs.

Unfair Competition

4.

The Defendant Dempsey Pump Company is not the alter ego of the Defendant Oscar E. Dempsey, and the latter did not exercise such domination and control of the said corporation that it was the mere agent or instrumentality of the said individual Defendant.

5.

Plaintiffs have failed to establish the averments of their second claim for relief, respecting unfair competition by the Defendants, and the issues upon said claim are found generally against the Plaintiffs and in favor of the Defendants. Specifically, the Court finds that Plaintiffs’ evidence tendered in support of its averment that the Defendant Walraven and others entered an association with the Defendants Dempsey Pump Company and Oscar E. Dempsey in violation of a relation of trust and confidence with the Plaintiff Kobe, Inc. is insufficient to prove the said averment, and the Court finds no violation of any such relation to have occurred. The Court further finds that none of the Defendants at any time have hired away any employee of the Plaintiff Kobe, Inc., but that employments by any of the Defendants of former employees of Kobe, Inc. occurred only after severance of the employment relation by such employee for causes other than inducement of the Defendants.

Validity and Infringement of Plaintiffs’ Patents

6.

Plaintiff Kobe, Inc. is the owner of United States Letters Patent No. 1,907,-951, No. 2,081,220, No. 2,473,864, and No. 2,081,223 and is a licensee under United States Letters Patent No. 1,907,-947.

7.

Plaintiff Alta Vista Hydraulic Company, Ltd. is the owner of United States Letters Patent No. 1,907,947.

8.

Only claims 7, 8, 9, 10, 19, and 20 of Letters Patent No. 1,907,947 are here in suit. All of such claims in suit relate to a hydraulically operated pumping mechanism for use in a bored well. Such hydraulic pump is designed to be set at or near the bottom of an oil well, and is actuated by the delivery thereto of liquid power fluid through suitable tubing from the surface of the ground. All of such claims in suit are combination claims covering such mechanism which includes a differential-area engine piston, and by that is meant an engine piston having a small area continuously exposed to a supply of liquid at relatively high pressure, and a larger area alternately exposed to high liquid pressure and lower liquid pressure to reciprocate the piston. By the use of such a construction in a hydraulic pump, a number of advantages were obtained, i. e., simplicity of the parts of the mechanism and a better utilization of the small well space available for such a pump, a slow pumping stroke and a fast return stroke was obtained, and the engine piston assembly was positively actuated on both of its strokes. The patentee by such construction obtained an increased pumping rate over that obtained by his earlier patented hydraulic pump designs exemplified by Defendants’ Exhibits 9 and 19. Claims 19 and 20 of such patent in suit additionally *344 provide for the application of cléan power oil to a medial portion of the piston assembly to keep the piston assembly clean, and was an added advantage as it reduced wear on the piston.

9.

The inventions defined by the claims in suit of Letters Patent No. 1,907,947 constituted substantial contributions to the hydraulic pump art as it existed at the date thereof and were for substantial improvements in such hydraulic pumps. Hydraulic pumps embodying such inventions have been manufactured and sold by Licensees under said Letters Patent in suit, and have enjoyed a limited commercial success to the extent of seven pumps sold. Starting in the year 1937, Plaintiff Kobe, Inc. and its predecessors have built two 'single acting pumps of types similar to that disclosed in said Letters Patent No. 1,907,947 and have continuously tested such pumps. Also licensed under said Letters Patent No1. 1,907,947 is National Supply .Company, a stranger to . this action, but it has never manufactured or sold any pumps under such license, and such license was acquired by said National Supply Company in settlement of an interference proceeding in the United States Patent Office. The predecessor of Plaintiff Kobe, Inc. first obtained a .license under said Letters Patent and other patents in 1934, and they have paid royalties in substantial amounts under said license to Plaintiff Alta Vista Hydraulic Company, Ltd., as is shown by “Plaintiffs’ Exhibit 6”, but neither has ever sold any pump under such license.

10.

The combination defined by each of the claims in suit of Letters Patent No. 1,907,-947 was novel in the art and embodied invention. None of the prior- art patents relied upon by Defendants herein shows or suggests the- inventions defined by any of such claims in suit. None of the prior art patents relied upon by Defendants herein shows a construction which is as nearly like the construction defined by such claims in suit as the prior patents which were considered by the United States Patent Office in connection with the application for Letters Patent No. 1,907,947. None of the claims in suit of Letters Patent No. 1,907,947 are anticipated by the Tucker Patent No. 1,614,765 and such claims in suit constitute invention over such Tucker patent. The presumption of validity attaching to the issuance of the patent in suit was strengthened by the proceeding had in the Patent Office upon the application for said Letters Patent in suit.

11.

Each of the claims in suit of Letters Patent No. 1,907,947, distinctly claims the invention.

12.

Defendants’ pumps which are charged to infringe the Plaintiffs’ Letters Patent No.
