2At page 2 of the Answer, the examiner inadvertently
refers to a Canadian Patent as the only prior art “relied upon
in the rejection [sic, rejections] of claims under appeal.”
However, the actual rejections set forth by the examiner at
pages 2 through 5 of the final rejection and pages 3 through 8
of the Answer indicate that the examiner is relied upon the
prior art references listed herein. This conclusion is also
supported by appellants’ Brief and Reply Brief.
