Ex Parte LANDINGHAM - Page 14




          Appeal No. 2000-0920                                                        
          Application No. 08/829,034                                                  


          the absence of any other argument in favor of the patentability             
          of claims 10, 37 and 38, the standing rejection thereof based on            
          Holt in view of Hirayama will be sustained.                                 
               Claim 18 depends from claim 11 and therefore requires, among           
          other things, that the bone implant be fabricated from an FDA               
          approved cermet.  Because, for the reasons explained infra, we              
          cannot understand precisely what is meant by the terminology                
          “fabricated from an FDA approved cermet,” we are once again                 
          constrained to reverse the examiner’s rejection of this claims as           
          being unpatentable over the applied prior art.  See Steele,                 
          305 F.2d at 862, 134 USPQ at 295 and Wilson, 424 F.2d at 1385,              
          165 USPQ at 496.                                                            
               New ground of rejection pursuant to 37 CFR § 1.196(b).                 
               Claims 11-18 are rejected under 35 U.S.C. § 112, second                
          paragraph, because the meaning of the term “an FDA approved                 
          cermet” appearing in claim 11 is not clear.                                 
               The purpose of the second paragraph of Section 112 is to               
          provide those who would endeavor, in future enterprise, to                  
          approach the area circumscribed by the claims of a patent, with             
          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            
                                         14
