Opinion

MURRAY, District Judge.

This cause came on regularly for trial before the Court, sitting without a jury, on the 29th and 30th days of September, 1954; that the parties, by written stipulation dated and approved by the Court May 6, 1954, agreed that the issues to be tried in this case are, as set forth in said stipulation, as follows:

A. The validity of U. S. Letters Patent No. 2,076,330, issued April 6, 1937, to Henry Hughes & Son, Limited, a corporation of Great Britain, as assignee of the inventors, A. B. Wood, F. D. Smith, and J. A. Mc-Geaehy, and particularly Claim 4 of said Letters Patent;
B. Whether or not the sale and/or use of the device exemplified by plaintiffs’ Exhibit 1 of this pretrial stipulation and submitted herewith infringes Claim 4 of the aforesaid patent;
C. Whether or not the plaintiffs own complete title to U. S. Letters Patent No. 2,076,330 and possess the right to sue for infringement thereof, and if so, which plaintiff or plaintiffs own such title and possess such right.

It was further agreed between the parties in said stipulation that the questions of damages, legally sufficient notice of infringement to defendants and compliance by plaintiff with the marking statute, 35 U.S.C.A. § 287, and its predecessor statutes be deferred until after the trial; thereupon oral and documentary evidence and stipulations were introduced by and on behalf of each of the parties, and at the close of all of the evidence the parties rested, and thereafter, within the time granted by the Court, each of the parties filed their briefs, and the cause was then submitted to the Court for its consideration and decision, and the Court having considered all of the evidence and testimony submitted at the trial of the cause, the stipulations of parties, and the admissions contained in the pleadings, and the briefs of counsel, and being fully advised in the premises, now makes and orders filed its Findings of Fact and Conclusions of Law as follows:

Findings of Fact

I

That plaintiff National-Simplex-Bludworth, Inc., is a corporation duly organized and existing, that the plaintiff Henry Hughes & Son, Limited, is a corporation duly organized and existing, and that plaintiff Kelvin & Hughes, Limited, is a corporation duly organized and existing.

II

That the defendants Robert H. Prothero and Mary E. Prothero, his wife, are individuals doing business under the name and style of Prothero Boat Co., and have a regular and established place of business at 2046 Westlake Ave. No., Seattle, Washington; that the defendants Robert H. Prothero and Mary E. Prothero are husband and wife and as such constitute a marital community, and that the defendant Robert H. Prothero in all things mentioned herein was acting for and on behalf of himself and this marital community.

III

That this is a suit arising under the patent laws of the United States.

IV

That on April 6, 1937, U. S. Letters Patent No. 2,076,330 were issued to plaintiff Henry Hughes & Son, Limited, as the assignee of the inventors Albert Beaumont Wood, Frederick Daniel Smith, and James Andrew McGeachy, for an invention of apparatus for the measurement of distances by echo reception methods. That by an agreement dated April 17, 1940, said Henry Hughes & Son, Limited, granted to International Projector Corporation an exclusive license under the said U. S. Letters Patent above mentioned to manufacture, use, exercise and vend in the United States of America the device covered by said patent, except the component part of an echo sounder called a receiving and transmitting oscillator. That there is no evidence before the Court that the said [148]*148plaintiff Henry Hughes & Son, Limited, has ever divested itself of any other legal or equitable interest in said patent than the license to International Projector Corporation hereinbefore mentioned, and the Court finds from the evidence before it that the plaintiff Henry Hughes & Son, Limited, is the sole owner of the legal title to said U. S. Letters Patent.

V

That there is no evidence before the Court from which the Court can find that the plaintiff Kelvin & Hughes, Limited, owns any interest, legal or equitable, or otherwise, in said U. S. Letters Patent No. 2,076,330, or any proceeds derived therefrom.

VI

That there is no evidence before the Court from which the Court can find that the plaintiff National-Simplex-Bludworth, Inc., owns any interest, legal or equitable, or otherwise, in said U. S. Letters Patent No. 2,076,330, or any proceeds derived therefrom.

VII

That defendants Robert H. Prothero and Mary E. Prothero, his wife, doing business under the name and style of Prothero Boat Co., at 2046 Westlake Ave. No., Seattle, Washington, sold the device, referred to in this trial as plaintiffs’ Exhibit 1, which is alleged to have infringed the U. S. Letters Patent above referred to.

VIII

That Claim 4 of said U. S. Letters Patent, which by agreement of the parties is the only claim of said patent in issue in this case, reads as follows:

“4. A transmitting member for use in apparatus for the measurement of distance by echo reception, comprising a tubular core of ring form laminations of magnetostrictive material .disposed so that they vibrate in a direction transverse to the axis of the core, a support for said core and sound .insulating means on said support to prevent the emission of sound waves from the inner curved face and one end of the .core, a reflector co-axial with the core and support and in sound reflecting relation to the outer curved surface of the core, and a liquid within said reflector.”

IX

That said Claim 4 discloses a new combination of component parts that were previously known in the field of sound and echo reception; that neither the Hayes patent, Nó. 1,985,251, nor any of the other patents introduced by the defendants disclose -the same combination of component parts as Claim 4 of the patent in suit, and that said Claim 4 of said patent is valid.

X

That the device above referred to as plaintiifs’ Exhibit 1, sold by the defendants, does not infringe upon Claim 4 of the patent in suit for the following reasons :

•1. Plaintiifs’ Exhibit 1 is a receiving oscillator and not a “transmitting member” as specified in Claim 4 of the patent in suit.
2. That while, with some modification, the accused device, plaintiifs' Exhibit 1, might be used as a transmitting member, it does not contain “sound insulating means on the support to prevent the emission of sound waves from the inner curved face and one end of the core”, as specified in said Claim 4 of the patent in suit, nor does it contain any equivalent of said sound insulating means.

From the foregoing Findings of Fact the Court draws the following .

Conclusions of Law

That this Court has jurisdiction hereof.

That the plaintiff Henry Hughes & Son, Limited, is the proper party plaintiff and has the right to maintain this action.
