                 Appeal No. 94-3846                                                                                                                     
                 Application 07/891,376                                                                                                                 



                          Having carefully studied the record before us, it is our determination that neither                                           
                 of the above noted rejections can be sustained.  Our reasons are set forth below.                                                      
                          The examiner points out that “[t]he polymer [of Yasui] is the product of emulsion                                             
                 or suspension or polymerization methods” and that “[e]mulsion polymerization includes                                                  
                 oil-in-water and water-in-oil arrangements, [wherein] the later [sic, latter] constitutes                                              
                 [the] claimed ‘dispersed [as] droplets in an inert organic phase’” (Answer,  page 3).  It is                                           
                 the examiner’s implicit position that the emulsion polymerization generally referred to                                                
                 by Yasui would include “water-in-oil arrangements” that would necessarily produce                                                      
                 polymer particles having a hydrophobic surface as required by the appealed claims.                                                     
                 However, the Yasui patent contains utterly no disclosure of a hydrophobic surface or of                                                
                 a hydrophobic suspending agent which results in the aforementioned hydrophobic                                                         
                 surface as recited in the appellants’ claims.  It is, therefore, clear that the examiner’s                                             
                 above noted position is improperly based upon conjecture, speculation, or assumptions                                                  
                 rather than a factual basis as required by § 103.  See In re Warner, 379 F.2d 1011,                                                    
                 1017, 154 USPQ 173, 178 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968).                                                               
                          The examiner’s rejection is further deficient with respect to his position                                                    
                 concerning the claim 1 step of “coating the polymer particles with a hydrophilic material                                              
                 in the absence of an organic solvent, such as to render the polymer surface                                                            
                 hydrophilic.”  Specifically, the examiner seems to equate this claimed step with Yasui’s                                               

                                                                           3
