         Appeal No. 2003-1038                                                       
         Application No. 09/262,628                                                 



         In addition, claims 1 through 4, 7, 8, 10, and 12 through 23 on            
         appeal stand rejected under 35 U.S.C. § 103(a) as unpatentable             
         over the combined teachings of Hammar and Pustka.  (Id. at pages           
         7-10.)4                                                                    
              We affirm the rejection under the written description                 
         requirement of 35 U.S.C. § 112, first paragraph, but reverse the           
         rejection under 35 U.S.C. § 103(a).5                                       
                  35 U.S.C. § 112, ¶1: Lack of Written Description                  
              In reply to the Office action mailed Apr. 18, 2001 (paper             
         9), the appellants amended the claims by replacing the term                
         “fluoropolymer” with “fluoroplastic.”  (Amendment filed Jul. 30,           


                                                                                   
              4  The examiner states that all other rejections set forth            
         in the final Office action have been withdrawn.  (Answer, p. 3,            
         ll. 1-4.)                                                                  
              5  The appellants submit that the claims should be grouped            
         as follows: (I) claims 1-4, 7, 8, 10, and 12-16; and (II) claims           
         17-23.  Concerning the rejection under 35 U.S.C. § 112, ¶1, the            
         appellants have not advanced any argument in support of the                
         separate patentability of claims 17-23.  Accordingly, for the              
         rejection under 35 U.S.C. § 112, ¶1, we confine our discussion             
         to claim 1.  37 CFR § 1.192(c)(7) (1995); In re McDaniel, 293              
         F.3d 1379, 1383, 63 USPQ2d 1462, 1465 (Fed. Cir. 2002) (“If the            
         brief fails to meet either requirement [as provided under 37 CFR           
         ? 1.192(c)(7)], the Board is free to select a single claim from            
         each group of claims subject to a common ground of rejection as            
         representative of all claims in that group and to decide the               
         appeal of that rejection based solely on the selected                      
         representative claim.”).                                                   

                                         4
