District Court, District of Columbia·Decided January 14, 1959·No. No. 505-57·Published

Opinion

HART, District Judge.

This Cause having come on for trial on December 10 and 11, 1958, and the parties having appeared by counsel and the Court having heard the testimony of Henry W. Haigh, Havard L. Keil, Ph.D., and Arthur Livermore, Ph.D., and having considered all the evidence, makes the following

Findings of Fact

I.

Plaintiff, Charles N. Cone, the applicant for patent herein, is a resident of Portland, Oregon. Plaintiff, American-Marietta Company, is an Illinois corporation having its principal place of business at 101 East Ontario Street, Chicago, Illinois. Defendant, Robert C. Watson, is United States Commissioner of Patents whose official residence is in the City of Washington, District of Columbia.

II.

Prior to April 7, 1950, Charles N. Cone made an invention pertaining to a blood glue and processes of making the blood glue. On April 7, 1950, Charles N. Cone [45]*45duly filed an application for Letters Patent on said invention in the United States Patent Office. Said application was made and filed in accordance with the laws of the United States and Rules of Practice of the United States Patent Office and was assigned Serial No. 154,-717.

III.

Thereafter, on October 13, 1954, the said Charles N. Cone filed an application for Letters Patent in the United States Patent Office in accordance with the laws of the United States and the Rules of Practice of the United States Patent Office, Serial No. 461,947, as a continuation in-part of the said application Serial No. 154,717.

IV.

The entire right, title and interest in and to said applications Serial Nos. 154,-717 and 461,947, and the inventions described therein, were duly assigned by Charles N. Cone to the United States Plywood Corporation, a corporation of New York, the same later being assigned by United States Plywood Corporation to American-Marietta Company, a corporation of Illinois.

V.

Said applications were duly prosecuted in the United States Patent Office in accordance with the laws of the United States and the Rules of Practice of the United States Patent Office. Said application Serial No. 154,717, but not the invention disclosed therein, was abandoned subsequent to the filing of said application Serial No. 461,947, and the said invention was preserved and prosecuted in Serial No. 461,947.

VI.

In application Serial No. 461,947 various claims on the invention, namely, claims 1-8, 11-17, 19, 25, 27 and 28 were allowed by the Primary Examiner. Certain other claims, namely, Claims 9, 10, 18 and 26 were rejected and the rejection of these claims was subsequently affirmed by the Patent Office Board of Appeals. These claims were thus refused plaintiffs.

These claims are as follows:

9. The process of making glue which comprises providing an aqueous blood material selected from the group consisting of fresh blood, an aqueous solution of soluble dried blood and mixtures thereof, the blood solids and water in said material varying from about 1:3 to 1:10, respectively, on a weight basis, coagulating the blood in said material while agitating it for maintaining the coagulated blood particles in finely divided condition and dispersed throughout the aqueous medium, and improving the adhesive qualities of the coagulated blood dispersion and rendering it alkaline by admixing therewith while the same is at a temperature below about 120° F. an adhesive conditioner comprising an alkali metal caustic.
10. The glue product of the process of claim 26.
18. The process of making a glue which comprises providing an aqueous blood material selected from the group consisting of fresh blood, an aqueous solution of soluble dried blood and mixtures thereof, coagulating the blood in said material by intimately admixing with the said material an acid blood-coagulating agent while agitating it for maintaining the coagulated blood particles in finely divided condition and dispersed throughout the aqueous medium, and improving the adhesive qualities of the coagulated blood dispersion and rendering it alkaline by admixing therewith while the same is at a temperature below about 120° F. an adhesive conditioner comprising an alkali metal caustic, the water and blood being present after the admixing in the relative proportions of from about 1 part of blood solids to about 3 to 10 parts water, parts being expressed as parts by weight.
26. The process of making glue which comprises providing an aque[46]*46ous blood material selected from the group consisting of fresh blood, an aqueous solution of soluble dried blood and mixtures thereof, the blood solids and water in said material varying from about 1:3 to 1:10, respectively, on a weight basis, converting said aqueous blood material into an aqueous suspension of coagulated blood particles selected from the group consisting of blood particles heat-coagulated at a temperature between about 120° F. and the boiling point of the aqueous blood material, and acid-coagulated blood particles, by coagulating the blood in said initially prepared aqueous blood material while agitating it for maintaining the coagulated blood particles in finely divided condition and dispersed throughout the aqueous medium; and improving the adhesive qualities of the coagulated blood dispersion and rendering it alkaline by admixing therewith while the same is at a temperature below about 120° F. an adhesive conditioner comprising an alkali metal caustic.

VII.

This suit was brought pursuant to Title 35, Sec. 145, U.S.C., by the plaintiffs seeking a determination that they are entitled to receive a patent on the invention defined in each of the aforesaid claims 9, 10, 18 and 26, and seeking a determination by this Court of the authority of the Commissioner of Patents to issue a patent containing said claims to plaintiffs.

VIII.

The claimed invention is primarily directed to the coagulation of an aqueous blood material while the same is being agitated to provide a finely divided coagulated blood material in aqueous medium, and to the addition, at a temperature below about 120° F., to the coagulated blood material of one or more conditioning chemical to render the same alkaline, thereby to produce an improved blood glue which has very desirable properties, particularly when used - in the plywood industry.

IX.

The blood glues of the invention have a fine uniform consistency and superior spreading properties over a wide viscosity range; they are stable in the presence of additives and have a high tolerance for phenol-aldehyde resins and coact therewith to produce superior glues; they do not dry out rapidly or penetrate excessively into wood surfaces to which they are applied, thus affording the plywood manufacturers a long assembly time, a feature which is important; and these glues are useful in plywood manufacture under cold pressing as well as hot pressing conditions.

X.

The invention has received wide acceptance in commerce and in the plywood field.

XI.

The reference patents and publication cited by the United States Patent Office upon which the rejection of claims 9, 10, 18 and 26 are based, is: Keil et al. Patent 2,466,710, Cone Patent 1,976,436, Hawk “Practical Physiological Chemistry” 1947 (pages 422, 423).
