          Interference No. 103,036                                                    


          that the indicator material "composition can be a liquid crystal            
          composition."  There is no limitation that this composition is              
          used only for voltage sensitive indicator embodiments.                      
                    We agree with the party Burroughs et al.'s opposition             
          brief, page 145, that the Burroughs et al. specification has                
          sufficient written description for thermochromic.  Thermochromic            
          is defined in Webster's Third New International Dictionary (1964            
          Edition) (BX 18) as exhibiting thermochroism and thermochroism is           
          defined as the phenomenon of reversible change of color of a                
          substance with change of temperature.  As such, thermochromic               
          material is adequately supported by the disclosure in column 8,             
          lines 66 to 68, of a color indicating, heat sensitive material              
          which undergoes a nonpermanent color change when exposed to a               
          predetermined temperature.  The term, "thermochromic tapes," is             
          equivalent to the strip or layer embodiments of the color                   
          indicating heat sensitive material as disclosed in column 8,                
          lines 59 to 62, and column 11, lines 21 to 23.                              
                    For the foregoing reasons, the motion is denied as to             
          item 10.                                                                    
                   In item 11, the motion urges that the Burroughs et al.            
          specification does not contain a written description for the                
          "color to colorless," "colorless to color," and "one color to a             
          second color" limitations, which are present in reissue claims              



                                        -57-
