              Appeal No. 1996-2115                                                                                            
              Application 08/809,933                                                                                          


                      Upon presentation of new facts, it is necessary to consider the evidence of                             
              obviousness relied upon by the examiner and to weigh such evidence anew against the                             
              evidence of nonobviousness relied upon by the appellants.  In re Johnson, 747 F.2d 1456,                        
              1460, 223 USPQ 1260, 1263 (Fed. Cir. 1984).                                                                     
                                                                 •  •                                                         
                      The examiner asserts that “Examples 1 - 6  fail to demonstrate unexpected results                       
              over Flesher.  These examples fail to specify any particle size information.  As stated                         

              by the Board of Patent Appeals in the patent application, these examples are of little                          
              probative value” (answer, page 11).   It is clear from this statement that the examiner has                     
              not considered the evidence presented in Table 1 in light of appellants’ statement that the                     
                                                          •  •                                                                
              particle size of comparative emulsions 1 - 6  is 1.0 micron.  This is error.  In re Hedges,                     
              783 F.2d 1038, 1039, 228 USPQ 685, 686 (Fed. Cir. 1986).                                                        
                      The data show that the polymers formed using the emulsion polymerization                                
              procedure (reverse phase polymerization) of Examples 1*-6*, which appear to be                                  
              representative of Flesher, do not have the claimed solution viscosity (S.V.) and the                            
              solubility quotient (CEQ).  At this point the burden shifts to the examiner to explain why the                  
              data does not provide a sufficient rebuttal of the prima facie case.  Absent a fact based                       
              explanation from the examiner why the data in Table 1 does not constitute an effective                          
              rebuttal, the examiner has not sustained his burden.  Accordingly, we reverse                                   
              this rejection.                                                                                                 


                                                              6
