                 Appeal 2006-2601                                                                                   
                 Application 10/364,286                                                                             

                     We consider first the Examiner's § 102 rejection of claims 1-4 over                            
                 Sumiya.  We concur with the Examiner that the claimed synthetic gem that                           
                 comprises elements recovered from human remains is described within the                            
                 meaning of § 102 by Sumiya.  Both the claimed synthetic gem and the                                
                 synthetic diamond of Sumiya comprise elemental carbon and, as explained                            
                 by the Examiner, there is no distinction whatsoever in elemental carbon                            
                 recovered from human remains or derived from any other source.  Simply                             
                 put, carbon is carbon.  While Appellant maintains that the principles for                          
                 examining product-by-process claims do not apply to appealed claims 1-4                            
                 because they are not product-by-process claims, we do not agree.  The claim                        
                 recitation "recovered from human remains" is a process step which defines                          
                 how the elements of the synthetic gem are derived.  In any event, even if                          
                 claims 1-4 on appeal are not classical product-by-process claims, it is well                       
                 settled that when a claimed product reasonably appears to be substantially                         
                 the same as a product disclosed by the prior art, the burden is on the                             
                 Applicant to prove that the prior art product does not necessarily or                              
                 inherently possess characteristics attributed to the claimed product.  In re                       
                 Spada, 911 F.2d 705, 708, 15 USPQ2d 1655, 1658 (Fed. Cir. 1990); In re                             
                 Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA 1977); In re                                    
                 Fitzgerald, 619 F.2d 67, 70, 205 USPQ 594, 596 (CCPA 1980).  In the                                
                 present case, it is incumbent upon Appellant to establish that there is, in fact,                  
                 some difference in composition or structure between gems within the scope                          
                 of claims 1-4 and gems reasonably described by Sumiya.  However, as                                

                                                         3
