Appeal No. 1998-1273 Application No. 08/624,148 required by claim 1, part (c). The examiner has cited Dandekar as suggesting temperature control or isothermal beds (Answer, page 3, citing col. 7, ll. 35-45). However, this disclosure in Dandekar relates only to attempts to “minimize the temperature increase” in the reactor beds and does not disclose or suggest isothermal operation (see col. 7, ll. 37- 38). The examiner cites col. 13, l. 30-col. 14, l. 40 of Keefer (Figure 8) to show the embodiment of Keefer directed to the water gas shift reaction (Answer, page 4). However, claim 1, part (c), step (1) calls for reaction conditions sufficient to convert carbon dioxide and hydrogen to carbon monoxide and water, i.e., the reverse water gas shift (see the specification, page 1, ll. 11-16, and page 8, ll. 1-10). The examiner has not explained why one of ordinary skill in the art would have modified the reaction conditions of Keefer to attain the reaction conditions required by claim 1 on appeal. The examiner has also not explained by convincing evidence or reasoning why the prior art discloses or suggests the “predetermined time sequences” as required by claim 1 on appeal. Furthermore, the examiner has merely stated that 9Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
