          Appeal No. 96-2298                                                          
          Application 08/147,179                                                      


          and the respective viewpoints of appellants and the examiner.3              
          As a                                                                        


          consequence of our review, we make the determination which                  
          follows.                                                                    
               We reverse the examiner’s rejection of appellants’ claims              
          under the second paragraph of 35 U.S.C. 112.                                

               In assessing the indefiniteness issue raised in this                   
          appeal, we keep in mind the following principles.  Relative to              
          the requirements of 35 U.S.C. § 112, second paragraph, the                  
          court in In re Hammack, 427 F.2d 1378, 1382, 166 USPQ 204, 208              
          (CCPA 1970) stated that                                                     

                    [i]ts purpose is to provide those who would                       
                    endeavor, in future enterprise, to approach                       
                    the area circumscribed by the claims of a                         
                    patent, with the adequate notice demanded                         
                    by due process of law, so that they may                           
                    more readily and accurately determine the                         
                    boundaries of protection involved and                             
                    evaluate the possibility of infringement                          

               In the brief (pages 6 through 8), appellants discuss an amendment3                                                                     
          after final rejection. This amendment was denied entry (Paper No. 9). Review
          of the appropriateness of the denial of entry of an amendment is by way of  
          petition, not appeal. Thus, the content of the amendment is not before us, and
          we will not address the substance of the aforementioned discussion by       
          appellants in the brief.                                                    
                                          3
