          Appeal No. 98-1291                                                          
          Application No. 08/586,524                                                  

          examiner and the appellants as set forth in the Answer and the              
          Briefs.                                                                     
                       The Rejection Under 35 U.S.C. § 102(b)                         
               Anticipation is established only when a single prior art               
          reference discloses, expressly or under the principles of                   
          inherency, each and every element of the claimed invention.                 
          See RCA Corp. v. Applied Digital Data Sys., Inc., 730 F.2d                  
          1440, 1444, 221 USPQ 385, 388 (Fed. Cir.), cert. dismissed sub              
          nom., Hazeltine Corp. v. RCA Corp., 468 U.S. 1228 (1984).                   
               The examiner finds all of the structure recited in                     
          independent claim 1 in the transport trailer disclosed by                   
          Koch.  We agree with the appellants that such is not the case.              
          This reference suffers from several shortcomings.  First, in                
          our opinion, the requirement that the pivot axis of the ramps               
          be “spaced toward said second side of said main frame”                      
          (emphasis added) should, in view of the appellants’                         
          specification, be interpreted to exclude the situation where                
          it is spaced beyond or outwardly of the second side of the                  
          main frame, as is the case in Koch (see Figure 5).  Therefore,              
          Koch does not disclose or teach this limitation.  In addition,              
          claim 1 requires that the first end portion of each of the                  

                                          4
