Appeal No. 2000-1415
Application 09/197,947
Appellants’ invention pertains to a toilet sealing ring
adapter assembly for use in forming a connection to a sewer
pipe. A basic understanding of the invention can be derived
from a reading of exemplary claim 20, a copy of which appears
in the APPENDIX to the brief (Paper No. 11).
As evidence of obviousness, the examiner has applied the
documents listed below:
Gaddy 3,012,252 Dec. 12,
1961
Pickard 3,501,172 Mar. 17,
1970
Izzi, Sr. 4,482,161 Nov.
13,
1984
The following rejection is before us for review.
Claims 20 and 23 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Pickard, Gaddy, and Izzi, Sr.
The full text of the examiner’s rejection and response to
the argument presented by appellants appears in the answer
