                Appeal No. 2006-0881                                                                                                          
                Application No. 09/928,139                                                                                                    

                         The examiner’s obviousness position with respect to the obviousness-type double                                      
                patenting rejection parallels her obviousness position with respect to the § 103 rejections.  Thus,                           
                the former rejection is deficient for reasons previously explained with respect to the latter                                 
                rejections.  We also cannot sustain, therefore, the obviousness-type double patenting rejection of                            
                claims 1-8 as being unpatentable over claim 1 of Zavareh ‘453 in view of the Miller Chemical                                  
                Abstracts, the Barry Chemical Abstracts or Miller ‘261 in view of Harris.                                                     
                         In conclusion, we have not sustained any of the rejections advanced on this appeal                                   
                because the examiner has failed to carry her initial burden of establishing a prima facie case of                             
                unpatentability with respect to each of these rejections.  See In re Oetiker, 977 F.2d 1443, 1445,                            
                24 USPQ2d 1443, 1444 (Fed. Cir. 1992).                                                                                        


                                                          ADDITIONAL MATTER                                                                   
                         On page 6 of the supplemental brief, the appellants request “acknowledgement of                                      
                Appellants’ claim to foreign priority for both the GB 9602174.6 and GB 9618836.2 British                                      
                applications under 35 U.S.C. § 119 in the subject ‘139 application.”                                                          
                         The issue of foreign priority benefits is not relevant to any of the rejections before us in                         
                this appeal.4  Therefore, the issue raised by the appellants’ afore-quoted request is petitionable                            
                rather than appealable.  See MPEP § 1201.                                                                                     
                         Under these circumstances, it would not be appropriate for this panel of the Board to                                
                entertain on the merits the request under consideration.                                                                      

                                                                                                                                             
                4   For example, each of the references relied upon by the examiner in her rejections of the independent claim on             
                appeal would be available as prior art regardless of whether the appellants’ foreign priority claim is acknowledged           
                or perfected.                                                                                                                 

                                                                      7
