          Appeal No. 97-3030                                                          
          Application No. 08/254,181                                                  


          uniform, clean radiant heat.  With such a teaching in mind, in              
          view of Pons Pons’ teaching of using a heating element                      
          adjacent a fragrance bar to heat the fragrance bar in an air                
          freshener, it is our view that the skilled artisan would have               
          found it obvious to employ a porcelain enamel metal substrate               
          to heat the fragrance bar in Pons Pons.                                     
               Appellants contend that Hedden is not analogous art and                
          therefore would not be combinable with Pons Pons.  We disagree              
          for the reasons stated supra with regard to Yamamoto.  That                 
          is, although Hedden is not directed to air fresheners, the                  
          artisan looking for heating elements to use in Pons Pons,                   
          which suggests the use of a heating resistance but is not tied              
          to any particular heating element, would have looked to the                 
          heating arts of which Hedden is a part.  Hedden is clearly                  
          reasonably pertinent to the problem, i.e., heating, with which              
          appellants were concerned.                                                  
               We do not find the examiner’s rejection to be                          
          unreasonable because Hedden is not directed to either air                   
          fresheners or to any particular application of the disclosed                
          heating panels.  The rejection is based on a combination of                 
          references, e.g., Pons Pons and Hedden.  The artisan looking                
                                          8
