Appeal No. 98-0028 Application No. 08/455,912 outer sleeve having an external surface on which at least one barb is positioned for engaging the surface of the wall of the bore and on which a peripheral seal is positioned, and a stop on the coupling for engaging the outside surface of the wall adjacent the bore so that it arrests the insertion of the coupling into the bore. This claim stands unpatentable over the combined teachings of Puttonen and McGugan, the examiner’s position being that Puttonen discloses all of the claimed subject matter except for the stop, which is taught by McGugan. We do not agree. The examiner has not pointed out, and we are at a loss to find, the required “at least one barb” positioned for engaging the surface of the bore in the Puttonen device, which is held in place by the frictional interaction of a plurality of compressible ribs that cause the coupling to become “tightly wedged” in the bore (column 2, lines 38 and 39). Puttonen also fails to disclose or teach means for “arresting insertion” of the coupling into the bore, as is required by claim 17. In this reference, the uppermost rib does not perform such a function; while the coupling collar is pressed into the bore “until the upper rib is level with the mouth” 10Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
