Appeal No. 96-1055 Application 07/727,331 insufficient for the breadth of the claims, and argues that the dosages are speculative (answer, third and fifth pages) . The 2 examiner considers the specification to be merely an invitation to carry out excessive experimentation (answer, sixth page). These arguments are not well taken because they are not supported by the required evidence or sound technical reasoning. The examiner argues that appellants do not disclose any in vivo data in their specification or provide a correlation between the in vitro data therein and in vivo data (answer, third through sixth pages). This argument is not persuasive because it is directed toward the issue of utility and the examiner has not made a utility rejection. “Office personnel should not impose a 35 U.S.C. 112, first paragraph, rejection grounded on a ‘lack of utility’ basis unless a 35 U.S.C. 101 rejection is proper.” Manual of Patent Examining Procedure § 2107(IV) (7th ed., July 1998). 2The pages of the answer are not numbered. -4-4Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
