Appeal No. 1996-3675 Application No. 08/259,933 Examiner suggests because exposure of the internal half cell 32 to water would defeat the purpose of the Watanabe invention. The unsupported position taken by the Examiner is contrary to the specific teaching of Watanabe, Watanabe, when considered as a whole, does not supply any motivation to incorporate multiple holes into the reference electrode, and specifically teaches away from the structure suggested by the Examiner. Some teaching or suggestion in the references must exist to support their use of the particular applied combination. In combining Watanabe and Monter, the Examiner has impermissibly selected only so much of these references as necessary to support the Examiner’s position. The Examiner has ignored the teachings of these references which would lead one skilled in the art away from making the suggested combination. The suggested combination of elements of these references, therefore, is improper. [Underscoring added; appeal brief, pp. 11-12.] We agree with the appellant that the examiner has not supplied the requisite teaching or motivation to combine Watanabe with Monter. Our reviewing court has made it clear that “the best defense against the subtle but powerful attraction of a hindsight-based obviousness analysis is rigorous application of the requirement for a showing of the teaching or motivation to combine prior art references.” In re Dembiczak, 175 F.3d 994, 999, 50 USPQ2d 1614, 1617 (Fed.
