                   Appeal No. 95-0885                                                                                                                                  
                   Application 07/725,327                                                                                                                              


                             example, appellants draw the Board’s attention to the structural differences between                                                      
                             the elected species (see, e.g., claim 18) and the compounds discloses in Hindley.  The                                                    
                             Hindley compounds are limited to primary and secondary amino compounds ...                                                                
                   Other than claim 18, appellants have not presented arguments in their brief specifically arguing the                                                
                   separate patentability of any other dependent claim over the prior art as required by 37 CFR § § §                                                  
                   1.192(c)(5) and (c)(6)(iv) (1993).  Accordingly, dependent claim 18 will stand or fall on its own and                                               
                   dependent claims 2-7 and 9-17 will stand or fall independent claim 1.  In re Nielson, 816 F.2d 1567,                                                
                   1571, 2 USPQ2d 1525, 1527  (Fed. Cir. 1987); In re Wood, 582 F.2d 638, 642, 199 USPQ 137, 140                                                       
                   (CCPA  1978); Ex parte Schier, 21 USPQ2d 1016, 1081 ( Bd. Pat. App. & Int. 1991).                                                                   
                                                                            Opinion                                                                                    
                             We have carefully considered the respective positions advanced by appellants and the                                                      
                   examiner.  For the reasons set forth below, we will affirm-in-part the examiner's rejection of the                                                  
                   appealed claims for obviousness under 35 U.S.C. § 103.                                                                                              
                             Appellants argue, with regard to claim 18, that the thiazolidine derivative claimed therein                                               
                   includes a specie that is structurally distinct from the compounds of Hindley.  Appellants point                                                    
                   to the fact that Hindley’s compounds are limited to primary and secondary amino compounds.  In                                                      
                   response, the examiner asserts that                                                                                                                 
                             [a]ppellants argue for the first time that their active agents differ from the Hindley                                                    
                             compounds.  This argument is not persuasive as there is no evidence of record which                                                       
                             establishes the unpredictability of the resulting effect. [Answer, p. 4.]                                                                 
                   The burden is on the examiner to establish a prima facie case of obviousness, in this case establishing                                             
                   that the claimed compounds would have been structurally obvious over Hindley’s compounds.  It is                                                    
                                                                                 -5-
