                 Application No.  08/501,336                                                                              


                         The references relied upon by the examiner are:

                                              GROUND OF REJECTION4                                                        

                         Claims 1-3, 5-6 and 9-16 stand rejected under 35 U.S.C. § 103 as being                           
                 unpatentable over Doehner in view of Barnes.                                                             
                         We reverse.

                         Every case, particularly those raising the issue of obviousness under section                    
                 103, must necessarily be decided upon its own facts.  In re Jones, 958 F.2d 347,                         
                 350, 21 USPQ2d 1941, 1943 (Fed. Cir. 1992).  Furthermore, our appellate                                  
                 reviewing court has made it clear that there are no per se rules of obviousness or                       
                 nonobviousness.  In re Ochiai, 71 F.3d 1565, 1572, 37 USPQ2d 1127, 1133 (Fed.                            
                 Cir. 1995)(“reliance on per se rules of obviousness is legally incorrect.”)  Accord, In                  
                 re Brouwer, 77 F.3d 422, 425, 37 USPQ2d 1663, 1666 (Fed. Cir. 1996).                                     
                         According to the examiner (Answer, page 4) Doehner disclose “pyrrole                             
                 derivatives, structurally similar to the instant claimed compounds, which are highly                     
                 effective insecticidal, fungicidal and acaricidal, etc. agents….”  The examiner                          
                 argues (Answer, page 4) that “[t]he difference between the compounds of the prior
