                Application No. 09/037,409                                                                    

                for improving the breeding of farm animals with special reference to buffalo; a               
                milch animal of great economic importance in many countries.”  Id., page 4.                   
                                                 Discussion                                                   
                      The claims are directed to an isolated “sperm motility-promoting                        
                glycoprotein macromolecule having a molecular mass of 66 kda and purified to                  
                homogeneity” (claim 1), as well as methods of making and using such a                         
                glycoprotein.                                                                                 
                      The examiner rejected all of the claims as obvious over Mandal and                      
                Harris.  He characterized Mandal as teaching a sperm motility-promoting                       
                glycoprotein that reasonably appears to be the same as the glycoprotein                       
                disclosed in the instant specification.  See the Examiner’s Answer, page 3.  He               
                acknowledged that “[t]he Mandal et al[.] article does not teach purifying the factor          
                to homogeneity, and does not teach Appellants’ claimed method of purifying the                
                protein.”  Id.                                                                                
                      The examiner cited Harris as “disclos[ing] that protein purification using a            
                variety of different purification techniques in various orders is well-known in the           
                art.”  Id.  He concluded that                                                                 
                      [i]t would have been obvious to one of ordinary skill in the art at the                 
                      time Appellants’ invention was made to purify the factor of the                         
                      Mandal et al[.] article to homogeneity using the purification                           
                      techniques outlined in the Harris et al[.] text because it is routine                   
                      and desirable to purify proteins in order to produce an                                 
                      uncontaminated product having high specific activity and because                        
                      the purification techniques of the Harris et al[.] text are of wide                     
                      applicability in the purification of proteins in general.                               
                Id., pages 3-4.
