                Appeal  2006-2507                                                                                  
                Application 10/106,473                                                                             

                Mayne, 104 F.3d 1339, 1343-4, 41 USPQ2d 1451, 1455-56 (Fed. Cir. 1997)                             
                (“Applicant's conclusory statements” were insufficient to make a showing                           
                that “the claimed invention exhibits some superior property or advantage                           
                that a person of ordinary skill in the relevant art would find surprising or                       
                unexpected.”).                                                                                     
                       Accordingly, the rejection of claim 23 is affirmed.                                         
                                                        Claim 39                                                   
                       Claim 39 is rejected under 35 U.S.C. 103(a) as unpatentable over                            
                Kmiecik-Lawrynowicz in view of Lundy.  The Examiner found that                                     
                Kmiecik-Lawrynowicz discloses the invention as claimed with the exception                          
                of a specific disclosure of a combination of carbon black and magnetite                            
                (Answer 7).  The Examiner relies on Lundy for a teaching that a                                    
                combination of magnetite and carbon black is effective to give a magnetic                          
                toner with sufficient black coloring.  Id.  According to the Examiner:                             
                              It would have been obvious to one having ordinary skill                              
                       in the ad [sic, art] at the time the invention was made to add a                            
                       [sic] combine a carbon black dispersion with the magnetite                                  
                       dispersion when using magnetite as the colorant in Kmiecik-                                 
                       Lawrynowicz because Kmiecik-Lawrynowicz teaches                                             
                       that magnetite colorant dispersion and carbon black colorant                                
                       dispersion may be used in the toner process in combination                                  
                       while Lundy teaches that when magnetites are used in a color                                
                       toner carbon black is usefully included to improve the black                                
                       color of the toner. Thus, the artisan would have found it                                   
                       obvious to produce two dispersion[s] according to Kmiecik-                                  
                       Lawrynowicz, one with carbon black and one with magnetite                                   
                       such as the commercially available M08029, and add these                                    
                       dispersion at the colorant addition stage of Kmiecik-                                       
                       Lawrynowicz 's invention.                                                                   



                                                        8
