          Appeal No. 1997-1109                                                        
          Application No. 08/250,223                                                  
               In summary, the obviousness rejection of claim 25 is                   
          sustained.                                                                  
               Appellant argues (Reply Brief, pages 1-3) that the claims              
          on appeal should be allowed because the Office allowed similar              
          claims in Colson’s U.S. patent 5,520,450.  The PTO is not                   
          bound to repeat an error that may have been made in issuing                 
          the noted patent to Colson.  See Ex parte Tayama, 24 USPQ2d                 
          1614, 1618 (Bd. Pat. App. & Int. 1992).                                     
                                        DECISION                                      
               The decision of the examiner rejecting claims 22, 24, and              
          25 under 35 U.S.C. § 103 is affirmed.  The decision of the                  
          examiner rejecting claim 23 under 35 U.S.C. § 103(a)is                      
          reversed.  The decision of the examiner rejecting claims 1, 3-              
          6, 8, and                                                                   
          26 under 35 U.S.C. § 103 is reversed because of our finding                 
          that these claims are indefinite.                                           
               As a result of the indefiniteness of claims 1, 3-6, 8,                 
          and 26, this decision contains a new ground of rejection                    
          pursuant to 37 CFR § 1.196(b)(amended effective Dec. 1, 1997,               
          by final rule notice, 62 Fed. Reg. 53,131, 53,197 (Oct. 10,                 
          1997), 1203 Off. Gaz. Pat. & Trademark Office 63, 122 (Oct.                 
          21, 1997)).  37 CFR    § 1.196(b) provides that, ĦA new ground              
                                          9
