Appeal No. 2003-0318 Application 09/377,262 Reply brief, page 2. Although the examiner comments on the Frazier permeability and other features of the Jones and Singer references, the record is devoid of the examiner’s reasoning as to how these factors correlate to removal efficiency and initial quality factor. Moreover, we are in agreement with appellant that the record does not properly establish why one of skilled in the art would have been motivated to combine the teachings of Jones and Singer. The examiner seems to suggest that because Jones and Singer are drawn to the same field of endeavor, one having ordinary skill in the filter art would combine the teachings to arrive at a filter with high filtering efficiency. See examiner’s answer, page 5. However, the fact that Jones and Singer may be in the same field of endeavor is not sufficient to establish that one of ordinary skill in the art would have been motivated to combine their teachings. In this regard, we note that the examiner has even failed to provide reasoning as to why one of ordinary skill in the art would have been motivated to look to Singer given the fact that Singer does not relate to breathing mask fabrics that are suitable for use in an oily-misk environment. 6Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
