Appeal No. 95-1293 Application 07/727,387 the concentration of soluble fibrin in the body fluid". Where, as here, the examiner has not established that persons having ordinary skill in the art would have expected that the adsorption binding of Stemberger has the same strength and selectivity as the antigen/antibody binding of Scheefers- Borchel, we find that the references would not have led persons having ordinary skill in the art to appellants' method for quantitatively determining soluble fibrin in a body fluid with a reasonable expectation of success. At most, a person having ordinary skill would have found it obvious to try the proposed modification of the Scheefers- Borchel, per the teachings of Stemberger and "if necessary", Tom. Obvious to try, however, is an improper consideration in adjudicating obviousness. Hybritech Inc. v. Monoclonal Antibodies, Inc. 802 F.2d 1367, 1380, 231 USPQ 81, 91 (Fed. Cir. 1986).
