Appeal No. 1997-3307 Application No. 08/121,402 The mere fact that a certain thing may result from a given set of circumstances is not sufficient.” Ex parte Skinney, 2 USPQ2d 1788, 1789 (Bd. Pat. App. & Int. 1986). Here, the examiner has not provided the required evidence or technical reasoning showing that the methylcellulose derivative of the Burdkick references would necessarily has as bulk density of 0.30 g/cc or greater. The examiner has the initial burden of providing evidence or technical reasoning which shows that the methylcellulose derivative of Burdick ‘908 and ‘909, and the examiner has not carried out this burden. See In re Spada, 911 F.2d 705, 708, 15 USPQ2d 1655, 1657 (Fed. Cir. 1990); In re King, 801 F.2d 1324, 1327, 231 USPQ 136, 138-39 (Fed. Cir. 1986). Moreover, the examiner has not explained why one of ordinary skill in the art would have been motivated to modify the bulk density of the methylcellulose derivative to arrive at appellants’ claimed invention. Hence, we reverse both the 35 U.S.C. § 102(e) and 35 U.S.C. § 103 rejection over Burdick ‘908 and ‘909. Rejection III2 Because the reference of Knechtel does not cure the aforementioned deficiencies of the Burdick refereces (for reasons discussed later in this opinion) we also reverse 2 Appellants argue that Knechtel cannot be applied as prior art for the same reasons given in footnote 1.
