             Appeal No. 2006-2604                                                              Page 2               
             Application No. 10/253,066                                                                             

                    “By adding a[n] acyclic carboxamide to a menthol or mint type flavored chewing                  
             gum, one can obtain a strong cooling and clean minty flavor, without the higher                        
             concentrations of menthol or mint flavors required in the prior art.”  Id.  “Several U.S.              
             and foreign references disclose the acyclic carboxamides that are physiological cooling                
             agents. . . .  Some of these disclose the use of physiological cooling agents in chewing               
             gum.  These acyclic carboxamides (AC) include those disclosed in U.S. Patent Nos.                      
             4,296,255; 4,230,688; and 4,153,679.”  Id., page 6.                                                    
                    “Physical modifications of the physiological cooling agents by encapsulation with               
             another substrate will modify their release in chewing gum by modifying the solubility or              
             dissolution rate.  Any standard technique which gives partial or full encapsulation of the             
             combination of acyclic carboxamide can be used.”  Id.  “These techniques include . . .                 
             spray drying, spray chilling, fluid-bed coating, and coacervation. . . . Generally, a                  
             modified release of acyclic carboxamide is obtained in multistep processes like spray                  
             drying the acyclic carboxamide and then fluid-bed coating the resultant powder.”  Id.                  
             “The acyclic carboxamide can be treated to modify its release by being entrapped in an                 
             extrusion process.”  Id., page 10.  “The encapsulation techniques here described are                   
             standard coating techniques.”  Id., page 7.                                                            
                                                    Discussion                                                      
             1.  Claim construction                                                                                 
                    Claims 1, 2, 7-15, and 17-30 are pending and on appeal.  Appellants have                        
             presented separate arguments with respect to claims 11 and 18.  Appeal Brief, page 10.                 
             Therefore, those claims stand or fall by themselves; all other claims will stand or fall               
             together with respect to each rejection.  37 CFR § 41.37(c)(1)(vii).
