Opinion

RICH, Judge.

This appeal is from the decision of the Board of Patent Interferences awarding priority of the fifteen counts in interference No. 96,531 to the senior party, Joseph S. Wanberg, patentee of U. S. Patent No. 3,369,545, issued February 20, 1968, on an application filed September 25, 1964, entitled “Disposable Diaper with an Integral Container and Method for Disposal” and assigned to The Kendall Company. Appellant, Dale A. Gellert, is junior party, involved on his application serial No. 498,268, filed October 20, 1965, entitled “Disposable Diaper with Integral Disposal Bag” and assigned to Proctor and Gamble Company. We affirm.

The Invention

The invention to which all of the fifteen counts in issue are directed is a disposable or throw-away diaper having a fluid-impervious bag or pouch integrally attached to the outer or rear side of the diaper, the pouch being reversible, i. e., capable of being turned inside out, after the diaper has been used, to contain the soiled diaper and provide a convenient means for its disposal. Nine of the counts are directed to the disposable diaper structure and six to the method of manipulating the diaper to effect reversal of the pouch and form a container for the soiled diaper. The parties have treated all of the counts as standing or falling together on the issue before us. Representative are the broadest article and method counts, 1 and 5:

1. A disposable diaper having a length and width sufficient to fit around and cover the lower portion of the torso of a human body from the waist at the back of the body over the crotch to the waist of the front of the body, said diaper comprising a supple, fluid absorbent body and pouch integrate [sic] therewith suitably reversible for covering envelopment of a fluid-pervious surface of the diaper after use, said fluid absorbent body having a front side and a back side, said front side having a fluid-pervious surface for contact with a body, said back side having an impervious surface for preventing strike-through of fluid absorbed in said absorbent body, and said pouch having a wall portion thereof common with at least a portion of said impervious surface at the back side of said absorbent body and the remainder of the pouch wall comprising a supple, impervious sheet attached to said body whereby said impervious surface and said sheet form opposing wall portions of said pouch and define the pouch cavity at the back of said absorbent body when the absorbent body is in use.
5. In disposing of an absorbent article upon and in which are collected body fluids, said absorbent article comprising a supple fluid absorbent body having a fluid pervious front surface soiled by said fluids and a fluid pervious back surface and a fluid impervious sheet overlying said back surface and attached to said absorbent article to form a pouch therewith wherein said sheet and said body constitute opposing wall portions of the pouch defining the pouch cavity at the back of said absorbent article, the method comprising
turning said pouch inside-out by grasping a wall portion inside said cavity and moving said wall portions with respect to each other into a position in which the respective surfaces of said wall portions are positioned in substantially the reverse of their original positions so that said back surface of the absorbent body is disposed to the exte[781]*781rior and the soiled front surface is disposed to the interior of the cavity formed upon turning said pouch inside-out.

The Issue

The single determinative issue, under the view we take of this case, is whether Wanberg has established an actual reduction to practice prior to Gellert’s conception in May, 1963.

The Facts Surrounding Wanberg’s Reduction to Practice

While some of the facts surrounding the Wanberg reduction to practice are disputed, it is clear that Wanberg on at least one occasion made up a sample diaper embodying the invention and demonstrated his concept of a reversible pouch to his superior at the Kendall Company by the following acts, which Wanberg alleges show a reduction to practice. A conventional disposable diaper, which had a single layer of polyethylene film backing, was modified by the addition of a second sheet of polyethylene affixed to the film backing of the conventional diaper by pressure sensitive adhesive tape along three edges thereof to form an integral pouch. Then Wanberg reached into the pouch with his hand and reversed the pouch so it was “inside out” and the diaper itself was inside the bag formed by the reversed pouch.1

We must determine whether this demonstration is sufficient to constitute a reduction to practice of the invention of the counts. It is appellant’s position that “a reduction to practice under the circumstances of this case requires more than merely demonstrating the reversibility of an unused diaper, i. e., the bare demonstration of its principle of operation.” What in essence is lacking, according to appellant, is the testing of this invention under circumstances actually representing or simulating in-use conditions of the disposable diaper which has as its ultimate purpose the containment of excrement emanating from a baby.

Appellant’s Arguments

Appellant made before the board several arguments why he believed the facts do not show a reduction to practice, being essentially the reasons why he believed the invention could only be reduced to practice by applying the diaper to an infant. These arguments are repeated before us. Appellant noted that the counts all contemplate use of the diaper on humans and define a structure which is reversible “after use” or “soiled by body fluids or excrements” or relate to a method of disposing of an article “in which are collected body fluids” and which has a “front surface soiled by said fluids” and argued that the fact that the claims contain such references should dispose of the contention that it was not necessary to put the diaper on an infant to reduce the invention to practice. In appellant’s view such claim limitations established what could only be the intended functional setting for the invention and anything short of such application was not a reduction to practice.

Appellant also notes, as he did before the board, that without the application of the diaper to an infant, one could not be sure that the crushing and twisting of the diaper when in place upon an active infant would not so distort the pouch that it would no longer function upon reversal to contain the excrement. Finally, appellant questions the effect of pinning the diapers to hold them on the infant, in an apparent belief that the pinholes would so tear the pouch as to make it unable to contain the diaper upon reversal. On both of these [782]*782points, the crushing and pinning, appellant cites the testimony of appellee’s witnesses, elicited upon cross examination, questioning to some extent whether the invention would work under these conditions. As to the effect of pinning, appellant further notes before us that “on June 20, 1969, Wanberg filed an application * * * [on another invention] which issued as U. S. Patent 3,585,999 on June 22, 1971 — some two months after the oral argument below,” in which Wanberg noted that the disposable diapers “are subject to tearing during or after the operation of inserting safety pins, thus * * * causing points of possible leakage at the tears.”
