              Appeal No. 1997-3542                                                                                       
              Application No. 08/192,507                                                                                 


              the examiner states that the specification fails to provide an adequate written description                
              of the invention and fails to provide an enabling disclosure without complete evidence                     
              either that the claimed biological materials are known and readily available to the public or              
              complete evidence of the deposit of the biological materials.   Paper No. 5, page 2.  The                  
              examiner acknowledges that appellants have made reference to a deposit of 2G10                             
              hybridoma ATCC HB10436 on page 19 of the specification, but indicates that appellants                      
              have failed to provide sufficient assurances that the required deposit has been made and                   
              that all the conditions of 37 CFR § 1.801-1.809 have been met.  In addition, the examiner                  
              indicates that appellants have failed to address the requirement for deposit of 1C2                        
              hybridoma reference in claim 14.                                                                           
                     In order to sustain a rejection under 35 U.S.C. § 112, first paragraph, for lack of                 
              enablement, the examiner has the initial burden to establish a reasonable basis to                         
              question the enablement provided for the claimed invention.  See In re Wright, 999 F.2d                    
              1557, 1561-62, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993).  The examiner must provide a                         
              reasonable explanation as to why the scope of protection provided by a claim is not                        
              adequately enabled by the disclosure.  See In re Marzocchi, 439 F.2d 220, 223, 169                         
              USPQ 367, 369 (CCPA 1971).  In the present case, we believe that the examiner has met                      
              this burden.                                                                                               




                                                            5
