Appeal No. 2001-1392 Page 5 Application No. 08/900,586 In response appellants argue (Brief2, page 6) “[w]hile the [e]xaminer has correctly characterized the teachings of the cited references, it is not believed that these teachings fairly establish a case for prima facie obviousness for the present invention.” We agree. As appellants explain (Brief, page 8) it is not “the concept of ratioing the concentration of one analyte to another [that] is patentable or even novel,” instead it is appellants’ invention taken as a whole that is novel and unobvious in view of the prior art relied upon. According to appellants (id.) [t]he teachings by Baker et al[. and Besch] of a basic ratioing technique is not suggestive of the claimed invention … [and the Yip] “method for measuring analyte to creatinine ratios … is completely different from that of the present claims.” In response to appellants’ arguments the examiner simply restates his original conclusion (Answer, page 7) “the claimed invention appears to be an obvious variation of the reference teachings of determining the concentration of two analytes in fluids then normalizing the first analyte using the concentration of the second analyte.” We remind the examiner, as set forth in In re Kotzab, 217 F.3d 1365, 1369-70, 55 USPQ2d 1313, 1316 (Fed. Cir. 2000): A critical step in analyzing the patentability of claims pursuant to section 103(a) is casting the mind back to the time of invention, to consider the thinking of one of ordinary skill in the art, guided only by the prior art references and the then-accepted wisdom in the field. … Close adherence to this methodology is especially important in cases where the very ease with which the invention can be understood may prompt one “to fall victim to the insidious effect of a hindsight syndrome wherein that which only the invention taught is used against its teacher.” … 2 Paper No. 11, received May 7, 1999.Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
