                Appeal 2007-0284                                                                               
                Application 10/454,564                                                                         

                In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433-34 (CCPA 1977)                              
                (footnote omitted).  See also In re Spada, 911 F.2d 705, 709, 15 USPQ2d                        
                1655, 1658 (Fed. Cir. 1990) (“when the PTO shows sound basis for                               
                believing that the products of the applicant and the prior art are the same, the               
                applicant has the burden of showing that they are not”).                                       

                                                DISCUSSION                                                     
                      Appellants do not dispute that Murray discloses every limitation of                      
                claim 12, except the clause “wherein the aminosilicone and non-amino                           
                functionalized silicone are in the form of emulsion drops containing a blend                   
                of the aminosilicone and non-amino-functionalized silicone.”  (See Br.                         
                passim.)   Based on the laws of physics, in the absence of any evidence to                     
                the contrary, we find this disputed limitation is met:  Murray’s mixing of                     
                pre-emulsified amino silicone and pre-emulsified non-aminosilicone in his                      
                aqueous shampoo inherently results in at least some “emulsion drops                            
                containing a blend of the aminosilicone and non-amino-functionalized                           
                silicone,” as required by claim 12.  (See Answer 4.)                                           
                      We disagree with Appellants’ unsupported argument that Murray’s                          
                shampoo compositions “only contain emulsion drops of amino-                                    
                functionalized silicone and separate emulsion drops of non-amino-                              
                functionalized silicone” and thus are “structurally different from the claimed                 
                conditioning shampoo.”  (Br. 5.)  The Examiner has at least made a prima                       
                facie case to the contrary.  Appellants have not provided any evidence to                      
                rebut the Examiner’s prima facie case.  Thus, we affirm the Examiner’s                         
                § 102(b) rejection of claim 12.                                                                


                                                      6
