              Appeal No. 2005-2175                                                                                        
              Application 10/104,383                                                                                      

              Pollock and Nelson use different technologies because Pollock secures the plank directly to                 
              support members and the floor covering of Nelson has a decorative surface on the bottom surface             
              (id., pages 16-17 and 29).                                                                                  
                     Appellants contend that there is no justification for modifying the plank of Pollock in              
              order to join such planks using the T-shaped molding of Haid because Pollock attaches planks to             
              supports using screws, Pitman is directed to pathway marking systems and Nelson discloses a                 
              completely different type of flooring system using a tongue and groove joining system (id.,                 
              pages 21-23, 24-25 and 31).  Appellants further contend that Nelson teaches away from Haid                  
              because Nelson teaches that the bottom and top surfaces of the flooring “are flat (not beveled)”            
              and thus form a gapless seam, with no more than “a hint” in the reference that “the edge surfaces           
              may not form a completely gapless seam” (id., pages 23, 25 and 30).                                         
                     The examiner responds that Pitman is analogous prior art because it “deals with the                  
              common problem in both Pollock and in the instant invention of how to color PVC and is relied               
              upon by the examiner only for the solution of using pigments” (answer, pages 12-13).  The                   
              examiner further argues that the planks of Pollock can be secured to supports using other means             
              than screws, and with respect to Nelson, that the means of securing the flooring has nothing to             
              do with a backing layer (id., pages 14-15).  With respect to a “gap” in the flooring of Nelson, the         
              examiner contends that while “Haid teaches that the bevel (col. 4, lines 25-35) is decorative,”             
              [t]here is nothing in Nelson that would preclude a small surface gap if it were deemed a desirable          
              decorative feature,” pointing out that “[t]he main function of the groove system of Nelson is to            
              preclude separation of the planks, which is the purpose of the spline of Haid” (id., pages 17-18            
              and 19).  The examiner further contends that the difference in the connection systems of Pollock            
              and Nelson argued by appellants does not preclude the “transfer of the teachings of PVC being               
              an effective decorative layer in a floor panel [or] the transfer of a teaching of how to color a PVC        
              molding,” arguing that references in the same art area can be relied on for the teachings therein           
              even if the subject matter is structurally different, and that appellants have not established that         
              the teachings relied on are “taught away from by the reference being modified or would destroy              
              the function of the reference being modified” (id., pages 20-21).                                           
                     Appellants reply that “Pollock clearly relates to a deck plank, not a flooring plank” as             
              claimed, and, in this respect, “the planks of Pollock are used in a spaced-apart configuration,”            

                                                          - 11 -
