          Appeal No. 96-0215                                                          
          Application 07/975,908                                                      


          remaining claims are indefinite because they depend from                    
          claim 10.                                                                   
               Appellants argue on page 6 that it is clear how the filter             
          functions to decode the data to be detected.  Appellants point to           
          the specification, page 5, lines 30-32, which disclose that the             
          filter is designed to extract the features of the data.  Appel-             
          lants argue that in light of the specification, it is clear that            
          the filter decodes the data through feature extraction by spati-            
          ally modulating light which is directed to a mask encoded with              
          the data to be classified.                                                  
               In view of the Appellants' arguments and in light of the               
          teaching of Appellants' disclosure as it would be interpreted by            
          one possessing ordinary skill in the art, we find that the                  
          language "a filter for decoding the data to be detected" sets out           
          and circumscribes a particular area with a reasonable degree of             
          precision and particularity.  Therefore, we will not sustain the            
          rejection on the basis of 35 U.S.C. § 112 second paragraph.                 
               In regard to the 35 U.S.C. § 103 rejection, the Examiner has           
          failed to set forth a prima facie case.  It is the burden of the            
          Examiner to establish why one having ordinary skill in the art              
          would have been led to the claimed invention by the express                 


                                          4
