                   Appeal No. 2006-1065                                                                                              
                   Application No. 10/296,231                                                                                        

                           We consider first the examiner’s rejection under § 112, first paragraph,                                  
                   description requirement.  We agree with the examiner that the original specification fails                        
                   to provide descriptive support for the claim recitation “the particulate hydrophobic                              
                   polymers contain no active substance entrapped therein, distributed throughout, absorbed                          
                   or adsorbed.”  As appreciated by appellants, whether the claim recitation has original                            
                   descriptive support in the specification is a question of fact.  In the present case, we are in                   
                   agreement with the examiner that the facts do not support appellants’ contention that they                        
                   had possession, at the time of filing the present application, of the concept that the                            
                   claimed polymers contain no active substance entrapped therein, distributed throughout,                           
                   absorbed or adsorbed.  In re Anderson, 471 F.2d 1237, 1244, 176 USPQ 331, 336 (CCPA                               
                   1973).                                                                                                            
                           Our review of the original specification finds no indication that appellants                              
                   reasonably conveyed to one of ordinary skill in the art that they possessed the inventive                         
                   concept that the disclosed polymers have no association with active substances.                                   
                   Appellants rely upon the citation of U.S. Patent No. 5,476,660 at page 1 of the present                           
                   specification, lines 35-42 for evidence that they consider their polymers to be different                         
                   from the carrier particles of the cited patent.  However, the specification reference to U.S.                     
                   Patent No. 5,476,660 simply describes the prior art use of polymeric retention agents                             
                   having active substances embedded therein, but the specification provides absolutely no                           
                   disclosure that the present invention involves a departure from using the polymeric                               
                   particles as carrier particles.  Indeed, it is just as, if not more so, reasonable to conclude                    
                   that the polymeric particles of the present invention are intended to be employed as such                         
                   carrier particles.                                                                                                

                                                                 3
