          Appeal No. 2000-0023                                                        
          Application 08/967,856                                                      


          definition of "wood" is set forth. Indeed, although it is not               
          our burden to do so, we have scoured appellants' disclosure                 
          and have found no such definition for "wood."                               
               Accordingly, we have resorted to a standard, English                   
          language dictionary for a definition of "wood."  In "The                    
          Random House Dictionary of the English Language", Second                    
          edition, Unabridged, 1987, at page 2186, the first definition               
          for "wood" is:                                                              
               the hard, fibrous substance composing most of the                      
               stem and branches of a tree or shrub, and lying                        
               beneath the bark; the xylem.                                           
          Thus, the broadest, reasonable interpretation of the term                   
          "wood", in light of its ordinary, accepted meaning, includes                
          trees as argued by the examiner.                                            
               Accordingly, we agree with the examiner that because                   
          Phytophthora is shown by Hagar to attack almond and walnut                  
          trees and because Brouwer discloses that the therein disclosed              
          compounds, which are the active ingredients in the claimed                  
          method, effectively combat Phytophthora, it would have been                 
          prima facie obvious to "treat" almond and walnut trees with                 
          the agents disclosed in Brouwer to combat Phytophthora.  At                 


                                          9
