Appeal No. 2001-0246
Application No. 08/921,103
which the reference liquid contacts the sample liquid and the
possibility of cross contamination is increased. Therefore, as
the Examiner asserts, one of ordinary skill in the art would
have used the recirculating layout of Hofmeier for the reference
liquid of Europe which includes a constraint junction wherein
contamination of the reference fluid is less likely.
Based on our findings related to the applied prior art and
the analysis made above, we find that the Examiner has
established a prima facie case of obviousness. Therefore, the
35 U.S.C. § 103 rejection of claim 47 over Europe and Hofmeier
and of claim 49 over Europe, Hofmeier and Covington is
sustained.
