Appeal No. 2005-0687 Application No. 10/097,510 paragraph). We further agree with the examiner that Fruhstorfer establishes the obviousness of utilizing a thrust collar having a flange peripheral surface that is parallel to the center axis of the thrust collar. As noted by the examiner, each of the three designs for the thrust collars of Fruhstorfer has different structural shapes for different applications, and it would have been a matter of obviousness for one of ordinary skill in the art to select the particular design for the thrust collar which optimizes the retention of lubricant (see paragraph bridging pages 7 and 8 of Answer). As a final point, we note that appellant bases no argument upon objective evidence of nonobviousness, such as unexpected results, which would serve to rebut the prima facie case of obviousness established by the examiner for the claimed subject matter. In conclusion, based on the foregoing and the reasons well- stated by the examiner, the examiner's decision rejecting the appealed claims is affirmed. -8-Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
