Opinion

GARRETT, Chief Judge.

This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the rejection by the Primary Examiner, to whom we hereinafter refer as the examiner, of all the claims, numbered 11 to 15, inclusive, embraced in appellant’s application for patent for alleged “new and useful improvements in Highway Marking Paint Containing Glass Beads.”

Claims 11, 12, 13, and 14 are directed to a paint containing certain described pigments with which there is an admixture of minute transparent glass beads, the product as a whole being adapted to be sprayed on highway surfaces in lines marking the center of the highway and, where desired, in lines outlining traffic lanes and safety zones. Claim 15 is for the method of applying the paint product described therein, the method defined being by spraying.

*972 In view of the grounds of rejection, we here reproduce claims 11, 14, and 15:

“11. A quick-drying reflective highway marking paint essentially comprising a drying-oil-base varnish containing a brilliantly reflective pigment and additionally containing magnesium silicate pigment adapted to provide a false-body, the pigment volume ratio being about 25 to 45%', and a suspended admixture of transparent glass beads having an average diameter of the order of about 3 to about 10 mils and present in the proportion of about 3 to 8 pounds per gallon of bead-free paint, the beaded paint being adapted to be sprayed on highway surfaces subject to vehicular traffic to provide durable reflex light-reflective traffic markers which have a high night-time visibility to motorists.”
“14. A quick-drying pigmented reflective highway marking paint adapted to- bond to highway surfaces and resist weathering and traffic wear, characterized by containing a suspended admixture of transparent glass beads having an average diameter of the order of about 3 to about 10 mils, the proportions of pigment and of glass beads being correlated so that the beaded paint is adapted to be sprayed on highway surfaces subject to vehicular traffic to provide durable reflex light-reflective traffic markers which have a high night-time visibility to motorists.
“15. A single-step method of providing reflex light-reflective markers on highway surfaces, which comprises spraying upon a highway surface subj ect to vehicular traffic a coating of quick-drying pigmented reflective highway marking paint containing an admixture of transparent glass beads having an average diameter of the order of about 3 to about 10 mils, the proportions of pigment and of glass beads being correlated so that the resultant dried beaded paint coating will provide a durable reflex light-reflective marker which has a high night-time visibility to motorists.”

There are no limitations in claims 12 and 13 which distinguish them from the other claims in a patentable sense.

All the claims were rejected as unpat-entable over the disclosures of a patent, No. 2,268,537, issued December 30, 1941, to Leroy Shuger upon an application filed May 19, 1939.

That patent is the only prior art cited, and it presents the only ground upon which claim 11 was rejected.

The remainder of the claims were rejected additionally upon other grounds hereinafter stated.

It seems proper first to consider claim 11 and its rejection upon the Shuger patent standing alone. This patent embraces three claims all of which are for the product but, as stated in substance by the respective tribunals of the Patent Office, Shuger discloses a method of producing markings upon highways by first applying the paint defined in his patent claims in lines running on the surface of the highway and then sprinkling minute beads on the paint while it is in a tacky condition.

The beads applied to the wet paint by Shuger overlap in size those which appellant mixes in his paint before spraying it on the highway, and the pigment ingredients of Shuger’s paint are substantially the same in quality and quantity as those of appellant.

Shuger’s two-step method — that is, first applying the paint and then separately applying the beads on the wet paint — is disclosed clearly, although not claimed as a method, in his patent.

On the other hand, a disclosure of the application of appellant is that of premixing the beads with the paint and then applying.the mixture in a single step. As. has been stated, appellant presents claims for both the product and the method of applying it.

The purpose of the beads is to reflect light, particularly at night, and thus illuminate the painted lines.

The claims of the Shuger patent are for the “combined highway and lane line” resulting from the use of his paint plus the beads separately applied on it, as. may be seen from his claim 2 which reads: “2.

A combined highway arid lane line comprising a road surface, a reflecting binder thereon comprising pigment, non-volatile oil, and resin, and a series of autocollimating units partially embedded in said binder, the ratio *973 by volume of pigment to pigment, non-volatile oil, and resin being less than 50 per cent.”

Appellant’s claims (except No. 15) are for the product containing various elements, including beads, which have been mixed together. The elements, including the beads, are named also in claim 15, which is in method form.

It should be distinctly understood that the tribunals of the Patent Office did not rely upon the disclosure of the two-step method in the Shuger patent as an anticipation of the appealed claims which negatived invention on the part of appellant.

Their rejection of claim 11 is grounded solely upon their interpretation of certain phraseology appearing in Shuger’s specification from which interpretation they concluded that Shuger, as expressed by the examiner, made “a clear disclosure of the concept of a premixed marker paint containing glass spheres.”

The examiner said: “ * * * The point at issue is whether Shuger discloses a premixed paint containing the glass beads, or merely the formation of the highway marker by a two-step application such as has been previously described.” (Italics supplied by us.)

It seems to us that the question may be stated quite simply as follows: Does Shu-ger clearly and distinctly disclose a paint which has transparent glass beads as part of its composition in its finished state and before it is used in forming lines to’ serve as highway markers ?

That' is what appellant discloses and claims, and we are of opinion, upon the facts here appearing, that the Shuger patent must show that in order properly to be regarded as a pertinent reference.

In order to answer correctly the question so posed, it is necessary to interpret the phraseology of the Shuger specification, which impresses us as being somewhat ambiguous.

With respect to “whether Shuger discloses a premixed glass bead containing paint,” the examiner quoted the whole of the second paragraph and a part of the third paragraph of the Shuger specification reading:
