                Appeal 2007-4073                                                                               
                Application 10/739,417                                                                         
           1                                                                                                   
           2                                     ANALYSIS                                                      
           3          There are four grounds of rejection on appeal.  Before addressing the                    
           4    Examiner’s rejections and Leaphart’s responses, we first analyze Leaphart’s                    
           5    effective filing date and the scope of the disputed claim term “unidirectional                 
           6    seal.”                                                                                         
           7                                                                                                   
           8          The Effective Filing Date of the ‘417 Application Claims                                 
           9                                                                                                   
          10          The ‘417 application on appeal was filed on December 18, 2003.  The                      
          11    ‘417 specification claims benefit to the filing date of several parent                         
          12    applications, including U.S. Application 10/436,515, filed May 13, 2003,                       
          13    which issued as Leaphart ‘753.  The declaration filed for the ‘417                             
          14    application is consistent with the specification and likewise claims 35 U.S.C.                 
          15    § 120 benefit of the ‘515 application.  Additionally, the Examiner’s first                     
          16    office action stated that the present ‘417 application appears to be a                         
          17    continuation-in-part of the ‘515 application and Leaphart’s response to first                  
          18    office action identifies the present ‘417 application as a continuation-in-part                
          19    of the ‘515 application.  (First Office Action, p. 2, Amendment and                            
          20    Response dated June 24, 2005, p. 16).  Based upon the ‘417 specification                       
          21    and the ‘417 prosecution history, we find that the ‘417 application is a                       
          22    continuation-in-part of the ‘515 application filed May 13, 2003.                               
          23          Claims in the ‘417 application that are described and enabled by the                     
          24    specification of the parent ‘515 specification are entitled to an effective                    
          25    filing date of at least May 13, 2003.  Claims in the ‘417 application that are                 
          26    not described or enabled by the parent ‘515 specification are entitled to a                    
          27    filing date of December 18, 2003.  See, 35 U.S.C. §120.                                        

                                                      13
