Polaroid Corporation v. Horner, 197 F. Supp. 950, 131 U.S.P.Q. (BNA) 102, 1961 U.S. Dist. LEXIS 5364 (D.D.C. 1961).

Opinion

McGARRAGHY, District Judge.

This is an action under Section 146, 35 U.S.Code, in which plaintiffs Polaroid Corporation, as assignee, and William A. Shurcliff, as assignor, seek a judgment that Shurcliff was the first, original and sole inventor of the subject matter defined in Counts 1 to 6, inclusive, of an interference proceeding before the United States Patent Office; and that Polaroid is entitled to receive Letters Patent of the United States for said invention.

The invention in question relates to a radiation detection unit or dosimeter.

On May 13, 1952, Shurcliff filed an application for patent on a radiation detecting device or dosimeter. The application received Serial No. 287,535 and on January 10,1956, a patent, No. 2,730,625 was issued to Polaroid as assignee of Shur-cliff. Counts 3 and 4 of the interference correspond to claims in this patent.

On August 18, 1952, defendants Charles R. Horner and William F. Gray filed an application for patent on certain radiation detecting devices. This application received Serial No. 305,098. The remaining counts in interference, counts 1, 2, 5 and 6, originated as claims in this application.

On October 21, 1952, Shurcliff filed an application for patent on certain radiation detecting devices. This application received Serial No. 315,966.

Shurcliff on May 9, 1952 assigned to Polaroid all right, title and interest in and to Application Serial No. 287,535, and to the invention disclosed therein; and on October 16, 1952, he further assigned to Polaroid all right, title and interest in and to Application Serial No. 315,966, and to the invention disclosed therein.

On January 17, 1956, an interference was declared between applications Serial Nos. 305,098 and 315,966 and identified as Interference No. 87,809.

On June 5, 1956, Shurcliff filed an application for the reissue of patent No. *952 2,730,625 with consent of and on behalf of Polaroid. The reissue application received Serial No. 589,361. The interference was redeclared between the Horner and Gray application and Shurcliff reissue application Serial No. 589,361. Shurcliff was accorded the filing date of his first application — May 13, 1952 — and was, therefore, the senior party before the Board of Patent Interferences.

Both parties took testimony, filed briefs and appeared at the final hearing before the Board. On the basis of the evidence submitted to it, the Board of Patent Interferences ruled that Horner and Gray should prevail as to all counts and awarded priority of invention to them. Shurcliff filed a motion to reopen the record and a petition for reconsideration. The Board considered the petition but declined to modify its previous decision. Being dissatisfied with the decision of the Board of Patent Interferences, the plaintiffs brought this action.

Prior to the summer of 1950, Doctor James H. Schulman of the Naval Research Laboratory and others discovered that radiation could change the luminescent properties in silver phosphate glass. He proposed to the Bureau of Ships of the Department of the Navy that this be made the basis of a system of radiation dosimetry. Various tests had been run on this glass and Dr. Schulman had determined that a phosphate glass containing 8% by weight of silver phosphate would be the best type glass to use. It was further recognized that some type “reader” would have to be used in conjunction with the phosphor glass dosimeter. The discoverers were aware that the phosphate glass would be energy dependent and, prior to the fall of 1950, the exact quantitative degree of energy dependence was determined by Mr. Raymond Alger of the Naval Radiological Defense Laboratory. It was common knowledge at this time that energy-dependence could be reduced by lead shielding.

By March 15, 1950, the Navy Department knew that a phosphate glass dosimeter could be made and that it could be made substantially non-energy dependent by the use of suitable shielding and, on that date, the Department issued a military specification for a “Radiaemeter-Phosphor Glass Dosimeter”. Military Specification, MIL-R-15239 (SHIPS), 15 March 1950.

The specification required, among other things, that the work done under it be carried out in two phases. The first phase was to be a study to determine the suitability of phosphate glass detector materials for meeting the requirements of the specification and the second phase required the design and development of a radiacmeter. It was further specified that the radiacmeter would be both a self indicating and an indirect reading device and that it should include: (1) a phosphor glass detector, (2) color matching scale; (3) an ultraviolet light source; and (4) a photometer. The detector was to be made from non-critical materials and was to “be packaged in a pocket watch size water proof container * *. It is desirable that the overall dimensions of this container be not greater than 1% inches in diameter by V2 inch wide.” Military Specification, MIL-R-15239 (SHIPS), 15 March 1950, par. 3.7.1.

During the summer of 1950, Polaroid Corporation, the present plaintiff, was awarded a contract by the United States Government under the aforementioned specification. At the time of the award of the contract and at all times thereafter pertinent to the decision of this case, Shurcliff was employed as a physicist by Polaroid and was that company’s project leader for the dosimeter project. Shurcliff has a doctorate in physics and had extensive experience in the field of radiation and dosimetry. Horner and Gray, during the pertinent period, were employees of the Government in the Ra-diac Section of the Bureau of Ships, Department of the Navy, and were working under Adolph F. Lovoff, head of the Radi-ac Section. This section was responsible for the development of the Navy dosimeter program.

Horner was a project officer in the Radiac Section charged with administrative and technical responsibility for the *953 development of the dosimeter concerned. He also had extensive experience in the field of dosimetry. Gray was under Lovoff’s direction and was project engineer for the Radiac Section’s dosimeter program. Gray had extensive contact with the field of personnel dosimeters for about two years prior to the time the contract was awarded to Polaroid.

The period through September 1950 was primarily educational for Polaroid and included indoctrination by the Navy Department, visiting installations and talking with people who had been on the Navy program, as well as getting acquainted with outside manufacturers. There was also during this period and through the winter of 1950 an interchange of ideas regarding the dosimeter project between Polaroid personnel and personnel of the Radiac Section of the Navy.

In December of 1950 and January of 1951, Polaroid submitted to the Radiac 'Section of the Navy Department five dosimeter cases. However, none of these •cases was considered satisfactory. The manufacture of a satisfactory personnel •dosimeter was considered to be a crash project by the Radiac Section inasmuch as these dosimeters were to be used under actual conditions in a series of tests scheduled in Nevada in the middle of 1951. Lovoff became concerned about Polaroid’s failure to produce a satisfactory dosimeter and sometime in January, 1951, he instructed Horner and Gray to design a dosimeter case.
