               Appeal 2007-0650                                                                            
               Application 10/808,264                                                                      
               substituents containing one or more fused aromatic rings.                                   
               Alternatively, the radical can be “one or more non-fused aromatic                           
               rings without intervening functional groups.”  The only other option                        
               for the “Ar” group is a combination of the two alternatives recited                         
               above.  Therefore, where “Ar” includes fused rings, there can be                            
               substituents on the radical.  Where “Ar” includes two or more non-                          
               fused rings, there can be no functional groups between the rings.                           
               Where “Ar” is one non-fused ring, the language “no function groups                          
               between the rings” cannot apply.                                                            
                      Importantly, “n” is not limited by the claim.  We, therefore,                        
               interpret the claim as allowing n=1.  The claim only requires the                           
               presence of one  –(–O–Ar–)– structure.                                                      
                      We also note the use of the transitional phrase “comprising.”                        
               The use of “comprising” means that the claim is open to the inclusion                       
               of other structures in addition to the recited –(–O–Ar–)n– structure.                       
                      Based on the above analysis of the claims, we determine that                         
               claim 22 encompasses a process of making a polyaromatic ether with                          
               one –(–O–Ar–)– structural group where “Ar” is a single aromatic ring.                       
               We also determine that because the claim uses the transitional phrase                       
               “comprising,” the claim does not exclude carbonyl groups in other                           
               portions of the structure.                                                                  
                      Matzner describes polyaromatic ethers meeting the                                    
               requirements of claim 22.  See, for instance, formula (28) in columns                       
               17 and 18 of Matzner.  Formula (28) illustrates a block copolymer                           
               containing –(–O–Ar–)– structural groups wherein “Ar” is a single                            
               aromatic ring, i.e., a phenyl group.  While other sections of the
