                 Appeal No. 2002-0546                                                          Page 3                    
                 Application No. 08/809,379                                                                              

                 intravaginally in the third stage of labor,” i.e., administering misoprostol                            
                 postpartum.                                                                                             
                        Facts and Comparisons, according to the statement of the rejection,                              
                 “teaches that an agent known to cause uterine contractions and thereby induce                           
                 labor antepartum, is also known to be useful at increased dosages to cause                              
                 uterine contractions and thereby treat hemorrhaging post partum when firm,                              
                 tetanic contractions are known to be beneficial.”  Id. at 4.  Symonds is cited for                      
                 teaching that the postpartum stages of labor include the third and fourth stages,                       
                 and that these stages may last up to six hours after delivery.  See id.                                 
                        The rejection concludes:                                                                         
                                One of ordinary skill in the art would have found it obvious to                          
                        employ any agent known to cause uterine contractions antepartum                                  
                        to treat postpartum hemorrhaging since the agent would be                                        
                        expected to cause the firm, tetanic contractions known to be                                     
                        beneficial postpartum to control hemorrhaging when administered                                  
                        at an increased dosage.                                                                          
                 Examiner’s Answer, pages 4-5.                                                                           
                        Appellant argues that “the combination of [the] prior art of record in this                      
                 case fails to provide any reasonable expectation of success that oral                                   
                 administration of misoprostol or administration of misoprostol via pessary or                           
                 suppository during the third stage of labor would be effective at inhibiting                            
                 postpartum hemorrhaging.”  Appeal Brief, page 8.                                                        
                        Appellant asserts that just because a single agent, oxytocin, has been                           
                 shown to be useful in the first and second stages of labor, as well as the third                        
                 stage, the art provides no reasonable expectation that misoprostol, a different
