The examiner has not cited any evidence as to why it would have been obvious at the time the invention was made to a person having ordinary skill in the art to have modified the applied prior art to arrive at the claimed invention. Instead, the examiner found that the appellants did not disclose any new or unexpected results due to the height difference between the rejected claims and the applied prior art and then determined (answer, p. 5) that it would have been obvious to make the bushing in a smaller or larger size. However, it is well established that the mere3 fact that a difference between the teachings of the prior art and the claimed subject matter does not provide any new or 2The "height" of the bushing is measured from the top surface of the orifice plate to the bottom surface of the flange. 3We note that the examiner never determined that the claimed "height" would have been obvious at the time the invention was made to a person having ordinary skill in the art.Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
