                Appeal 2007-0525                                                                                 
                Application 09/919,794                                                                           
                                                DISCUSSION                                                       
                       The threshold issue is whether Blair is antedated by Appellants'                          
                affidavit under 37 C.F.R. § 1.131 (Rule 131).  The affidavit was submitted                       
                on July 20, 2004, and has been entered.2                                                         
                       The Examiner states that sufficiency of the affidavit is a petitionable                   
                matter (Answer 2, 6).  However, the sufficiency of a Rule 131 affidavit or                       
                declaration is clearly within the jurisdiction of the Board because it affects a                 
                rejection of the claims.  See In re DeBaun, 687 F.2d 459, 214 USPQ 933                           
                (CCPA 1982) (reviewing Board decision involving Rule 131 declaration).                           
                       37 C.F.R. § 131 provides that an applicant may establish invention of                     
                the claimed subject matter before the effective date of the reference and                        
                antedate the reference.  The tests are stated in § 1.131(b):                                     
                             The showing of facts shall be such, in character and weight, as                     
                       to establish reduction to practice prior to the effective date of the                     
                       reference, or conception of the invention prior to the effective date of                  
                       the reference coupled with due diligence from prior to said date to a                     
                       subsequent reduction to practice or to the filing of the application.                     
                       [Emphasis added.]                                                                         
                That is, there are three ways in which an applicant can antedate a reference:                    
                (1) actual reduction to practice of the invention prior to the effective date of                 
                the reference; or (2) conception of the invention prior to the effective date of                 
                                                                                                                
                       2  The Evidence Appendix in the Brief lists the affidavit, but does not                   
                include a "statement setting forth where in the record that evidence was                         
                entered in the record by the examiner" as required by 37 C.F.R.                                  
                § 41.37(c)(1)(ix).  We will overlook this informality.                                           
                                                       3
