          Appeal No. 95-2976                                                          
          Application No. 08/041,077                                                  

          groupings in the above noted rejections; see page 5 of the                  
          brief and 37 CFR § 1.192(c)(5)(1993).  Accordingly, in our                  
          assessment of the prior art rejection before us, we will focus              
          upon independent claims 4 and 16 (the sole independent claims               
          on appeal) with which all other rejected claims will stand or               
          fall.                                                                       
                                       OPINION                                        
               For the reasons which follow, we will sustain the above                
          noted prior art rejections but not the section 112, second                  
          paragraph, rejection.                                                       
               On page 3 of the answer, the examiner expresses his                    
          section 112, second paragraph, position in the following                    
          manner;                                                                     
               Degradable organic and polymeric are indefinite                        
               terms, as is "derivative" without specification of                     
               type i.e. - ester, etc.  Claim 9; or terms do not                      
               clearly modify polyether diamine.  Claim 10 is not                     
               clear as to the Markush species - are all                              
               polyesters?                                                            
               It is well settled that the definiteness of claim                      
          language must be analyzed, not in a vacuum but, always in                   
          light of the teachings of the prior art and of the particular               
          application disclosure as it would be interpreted by one                    
          possessing the ordinary level of skill in the pertinent art.                
                                          4
