         Application No. 09/351,147                                                 

              We reverse these rejections for the reasons well stated in            
         the appeal brief filed Mar. 25, 2002 (paper 22) and reply brief            
         filed Jul. 24, 2002 (paper 24), but add the following comments             
         for emphasis only.                                                         
                    I. Rejection under 35 U.S.C. § 102: EP ’736                     
              “To anticipate a claim, a prior art reference must disclose           
         every limitation of the claimed invention, either explicitly or            
         inherently.”  In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d              
         1429, 1431 (Fed. Cir. 1997); accord Glaxo Inc. v. Novopharm                
         Ltd., 52 F.3d 1043, 1047, 34 USPQ2d 1565, 1567 (Fed. Cir. 1995).           
              In addition, the prior art reference must disclose the                
         limitations of the claimed invention “without any need for                 
         picking, choosing, and combining various disclosures not                   
         directly related to each other by the teachings of the cited               
         reference.”  In re Arkley, 455 F.2d 586, 587, 172 USPQ 524, 526            
         (CCPA 1972); cf. In re Schaumann, 572 F.2d 312, 315, 316, 197              
         USPQ 5, 8, 9 (CCPA 1978)(holding that “the disclosure of a                 
         chemical genus...constitute[s] a description of a specific                 
         compound” within the meaning of §102 where the specific compound           
         falls within a genus of a “very limited number of compounds.”).            
              As argued in the appellants’ principal brief (page 4), “the           
         reference’s teaching that phosphorus oxide-free zeolites can be            
         used does not necessarily imply that phosphorus oxide-containing           

                                         3
