Appeal No. 95-1950 Application No. 08/061,928 We agree with the appellant that Mukogawa contains no teaching or suggestion of terminating the fluid signal in response to a selected change in the measured parameter as recited in clause D or for transferring the particles to an optical element for image analysis as recited in clause E of the independent claims under rejection. Concerning the clause D feature, the examiner urges that the "prescribed time in Mukogawa. . . is viewed as the presently recited measured parameter" (answer, page 6). This view is clearly erroneous since the here claimed "measured parameter" is explicitly defined in clause C as "responsive to fluid flow", and Mukogawa's time parameter is plainly not so responsive. As for the clause E feature, we cannot agree with the examiner that it would have been obvious to combine the prior art embodiment described in column 1 of Mukogawa with patentee's figure 1 embodiment. In our opinion, the appellant is correct in arguing that these embodiments are alternative, and thus not combinable, mechanisms for determining water purity. In light of the foregoing, we cannot sustain the examiner's section 103 rejection of claims 1, 3 and 8 as being unpatentable over Mukogawa. Moreover, we also cannot sustain 4Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
