Opinion

RICH, Judge.

This appeal is from the decision of the Board of Patent Interferences awarding priority to Ault et al., the senior party.1 Rion et al.2 appeal solely as to an issue which they assert, and which Ault denies, is ancillary to priority as hereinafter explained. We reverse and remand because we find there is no interference in fact.

The Counts

The parties’ inventions are both in the field of making vitreous enamels such as are applied to bathroom fixtures, kitchen sinks, and the like having a cast iron base. The counts recite a method of making a titania-opacified porcelain enamel frit and the frit made by that method. Frit is the intermediate, particulate glass material from which the enamel is formed in situ by fusion. We reproduce only the first count (subpara-graphing and emphasis of the terminology principally in issue supplied):

1. The method of making an improved titania opacified porcelain enamel frit for dry process application which comprises

fritting a molten silicate glass composition containing from about 8% to about 24% titanium dioxide by weight and
thereafter heat treating the frit-ted particles at a temperature sufficiently above the frit softening point, but below its fusion point, for a time period sufficient to cause nucleation of at least some of the titanium dioxide therein.

The counts are hybrids proposed by the examiner, and it was his use of the terms “softening point” and “fusion point” which has led to this appeal. The former expression was taken from ap-pellees’ specification, in which it is stated that

The range of heat treating temperatures extends from a temperature more than 100°F. above the softening point of the glass, but not more than 400 °F. above the softening point of the glass as measured by an interferometer. [Emphasis ours.]

The expression “fusion point” was taken from appellants’ specification, in which it is stated that the heat treating of the [572]*572fritted particles takes place “between 600°F. and 1300”F., [but] below fusion point of said frit.” However, appellants’ specification does not define “fusion point” or state how the fusion point of a particular frit can be measured.

Background,

It is now and throughout this interference has been appellant Rion’s contention that the terms “softening point” and “fusion point” are equivalent in this art. He has stated that,

While it is true that in the formed or flat glass industry, a distinction might be drawn between softening point and fusion point, this does not extend to porcelain enamels.

Pursuant to this contention, Rion brought three separate motions to dissolve the interference. The first was on the ground that the counts “are vague and indefinite constituting an informality in the declaration of such nature as to preclude a proper and adequate determination of the question of priority.” The second was on the ground that the counts “are unpatentable as being barred by * * * printed publications and patents * * * which * * * stand as a bar under 35 USC 102(b) and 35 USC 103 to patentability of the counts herein.” The third was on the ground that “the parties Ault et al. cannot make the counts because the disclosure of the parties Ault et al., as to the specific limitations of the count, is so vague and indefinite as to fail to support same.” However, as the primary examiner held in denying all three motions, the second and third motions were “based on the assumption that the party Rion succeeded in establishing in the motion to dissolve on ground (1), the equivalency of the terms as used in the counts viz ‘softening point’ and ‘fusion point’.”

The primary examiner held, without citation of authority, that

The art knows from observation and experience that the interferometer point applies to the point at which the glass begins to soften, and fusion flow 3 applies to the point at which the softened glass becomes molten and flows. [Emphasis in the original.]

The primary examiner also pointed to the statement in Ault’s specification that “For best results, the temperature should be below the point where tackiness occurs in the glass,” stating that

“Tackiness” describes a sticky or adhesive state, which when said of Ault’s glass would be recognized by one practicing Ault’s teaching as a softened state in which the glass is close to but below the fusion point.

Rion’s request for reconsideration was granted, but their motions were again denied. The opinion of the different examiner who rendered the decision thereon noted that

In a further effort to clarify their position they [Rion et al.] include a chart at page 3 by which they seek to persuade that they operate at mutually exclusive heating ranges from the party Ault * * *

but concluded that

Since both disclosures show reheating at 1100°F. (Ault at page 8 and Rion at page 15), the Rion chart is not found to have a basis illustrative of the facts as disclosed. [Emphasis ours.]

However, it should be pointed out, first, that the composition of the frit which Ault heat treated at 1100 °F. was not the same as the composition of the frit which Rion heat treated at 1100°F. and, second, that Ault heat treated the frit at that temperature for six minutes while [573]*573Rion heat treated the frit at that temperature for “about ten minutes.” Note that the counts relate temperature to “softening point” and “fusion point” and that different compositions may have such point or points at different temperatures.

Rion thereafter- petitioned the Commissioner, asking him to dissolve the interference in the exercise of his supervisory authority. This the First Assistant Commissioner declined to do on the ground that the primary examiner’s decision involved no “manifest error or abuse of discretion.”

At final hearing, Rion again contended that

* * * the expressions “fusion point” and “softening point” define the same temperature and since Ault et al. disclose heat treatment only at temperatures above the softening point of the fritted enamel particles, Ault et al’s. process neither supports the counts nor is directed to the same process defined by Rion et al. [Emphasis ours.]

The board’s original opinion, however, treats only the first part of Rion’s contention :

The heat treatment of the counts defines a temperature range or the transition between a point where the glass begins to soften and where it becomes molten. This is the definition placed on the counts by the Primary Examiner who, in drafting said counts for interference purposes, set forth the bounds to which the priority proofs of the parties would be limited. Under the circumstances of this case, particularly in view of the fact that neither party sought to change or modify the language of the counts, the definition of the terms of the counts by the Primary Examiner is controlling notwithstanding any alleged inconsistency with the technical definitions of the softening point and fusion point not found within the disclosures of the applications involved.
