            Appeal No. 2001-2168                                                      
            Application No. 09/083,307                                                

            § 1.192(c)(7), as amended effective April 21, 1995, to                    
            select a single claim from the group in question, namely                  
            group 1, and to decide the appeal of the claims in group 1                
            on the basis of the patentability of that representative                  
            claim alone.  Accordingly, we will select claim 9 as being                
            representative of group 1, with the result that the                       
            remaining claims in that group, namely claims 1-4 and 18-                 
            20, shall stand or fall with claim 9.  See also In re                     
            Young, 927 F.2d 588, 590, 18 USPQ2d 1089, 1091 (Fed. Cir.                 
            1991) and In re Wood, 582 F.2d 638, 642, 199 USPQ 137, 140                
            (CCPA 1978).                                                              
                 Claim 9 is directed to the system of inducing an                     
            immune response and reads as follows:                                     
                      A system for inducing an immune response against                
                 transformed, infected or diseased tissue comprising                  
                      a device for removing only components present in                
                 the blood having a molecular weight of 120,000 daltons               
                 or less, having inlet and outlet means for connection                
                 to a pump and tubing to recirculate the blood of a                   
                 patient through the device.                                          
                 As noted from the foregoing copy of claim 9, the                     
            structure recited in claim 9 comprises the filter device                  
            for removing only components having a weight of 120,000                   

                                                                                                                                                          
            identify the different groups of claims, whereas on page 11               
            of the main brief decimal numerals are used for this                      
            purpose. For consistency, we will use the decimal numerals                
            mentioned on page 11 of the brief for identifying the                     
            different groups of claims.
