Opinion

JACKSON, Judge.

This is an appeal from a decision of the Board of Appeals of the United States Patent Office affirming that of the Primary Examiner, finally rejecting as unpatentable all of the involved claims, 1, 3, 7, 8, 11, 12, 14, 15, 16 to 20, inclusive, and 22, of an application for a patent, serial No. 494,590, filed July 13, 1943, entitled “Process of Treating Yellowish or Off-White Materials to Obtain a White Appearance.”

The application relates to a process of treating textile materials, such as yarns, woven or knitted fabrics, paper and pulp products, having a yellowish or off-white tint, so as to obtain a pure white appearance. In the process, the articles may be treated at any stage of their manufacture or subsequent thereto by contacting them with a solution of a blue fluorescent compound of the coumarin group, preferably umbelliferone or methyl umbelliferone and aliphatic or aromatic derivatives thereof. The solution perferably contains a small amount of mild alkaline material, which, it is said, facilitates the solution of the compound and increases the fluorescence. The fluorescent material may be used simultaneously with a washing operation in which soap or other detergent is used, or preferably following a washing, such as in a rinse. The example set out in the application discloses a solution comprising 10,000 parts by weight of water, about 24 parts of borax and, one part of methyl umbelliferone.

Claims 12, 14, 15, 17, 18 and 22 are article claims, the other claims being for process.

The tribunals of the Patent Office considered claim 1 to be representative of the process claims, and' appellant in his brief 'has set up claim 12 as representative of the article claims. ' No- distinction has been made in the treatment- of the process and article claims by the board with the exception of claim 19. In addition to claim 19, claim 11 was separately considered by the Primary Examiner. Apparently the reason for such want of distinction between the two classes of claims was that patentable novelty in each claim depends upon the definition of the composition or material used.

Claims Í, 11 and 19 are considered representative of the claimed' patentable material in issue .and read as follows:

“1. The process of treating articles, substances and materials having a yellowish off-white tint, which comprises contacting the same uniformly with a solution of a compound of the coumarin group as the only material to affect the characteristics of the articles, substances and materials being treated, and which compound when dissolved produces a blue fluorescence whereby the yellowish off-white tint is eliminated and a pure white appearance is obtained.
“11. The process of treating textile fabrics having a yellowish off-white tint, which comprises contacting the textile fa- *933 brie uniformly with a weakly alkaline soap containing aqueous solution consisting of an alkyl substituted umbelliferone which when dissolved produces a blue fluorescence, whereby the yellowish off-white tint is eliminated and a pure white appearance is obtained.
“19. The method of improving the clearness and brightness of fibrous materials deficient in light reflecting properties under ordinary visible light which comprises treating the same with a small fraction of 1% of an organic substance emitting light of predetermined wave length under ordinary visible light, said predetermined wave length being selected to.compensate for the deficiency of reflected light of- the material treated by emitting light of a wave length missing in the reflection spectrum of the untreated material under ordinary visible light.”

Appellant filed an application for a patent, having the same entitlement as the involved application, in Great Britain on June 2, 1939, which matured into British patent No. 522,672, dated June 24, 1940. The application in issue here, which is said to be a corresponding United States application, was not filed until a little over four years subsequent to the British filing date because of the war.

The examiner made three statements with respect to his rejections. In the first statement all of the claims, with the exception of claim 11, were rejected as fully anticipated by appellant’s British patent All of the claims were further rejected as unpatentable over the Axelrad patent, No. 2,341,009, February 8, 1944.

In the examiner’s second statement, which was supplemental to the first, he withdrew the British patent as a reference for the stated reason that appellant had complied with the provisions of 60 Stat. 940 (1946), 35 U.S.C. § 101 (1946), 35 U.S.C.A. § 101, and was therefore entitled to the filing date of his British patent as to all claims except claims 2, 4, 9, 10 and 11. He added another reference, Ultrazell (Fr.) 803,753, July 20, 1936, and further rejected claim 19 on the ground that it was not fully disclosed in the application.

The Ultrazell patent has for its object a starch preparation for starching or sizing linen or other textiles. It is said that the process employed in the invention consists in the treatment of textiles, linen in particular, with a starch containing fluorescent chemical products, instancing ultraline (sodium beta methyl umbelliferone acetate). The patent depicts the starch preparation as follows: “The starch obtained in conformi'ty with the invention is distinguished, furthermore, by the fact that by the addition of fluorescent materials soluble in water a homogeneous distribution of the substance is . rendered possible. Thus we obtain, as compared with ultramarine blue soluble in water or analogous products a better shading of the starch as such or of the textiles .treated by it.” and speaks of the results of the process of the patent by stating that: “The textiles treated according to the invention have, after the starching, a pretty white color which may have, depending on the quantity or the nature of the fluorescent substance applied, a slighter shading toward another color, for example blue or rose. Furthermore the invention combines in a single operation the processes of bleaching, bluing and starching which have been followed, at least in part, up to the present.”

The examiner in his supplemental statement held claims 1 to 10, inclusive, 12 to 18, inclusive, and 20 to 22, inclusive, to be unpatentable over the Ultrazell patent because he deemed that no invention would be involved by omitting the starch of the patent and its function. The examiner held that claims 1, 3, 7, 8, 12 and 14 to 18, inclusive, do not distinguish over the Ultrazell patent because the meaning of the phrase in each of those claims, “as the only material to affect the characteristics of the textile fabrics,” is doubtful. He stated that starch does not have any chemical effect on fabrics and that just what characteristics would remain unaffected is not specified.

Claim 11 was deemed unpatentable over the Ultrazell'reference because, as the examiner stated, “Apparently all alkaline substances are equally well suited for aiding the dissoution [sic] of the umbelliferone. Borax is the alkaline agent in the only de *934 tailed example of applicant, and borax is shown by Ultrazell.”
