            Before BARRETT, GROSS, and BARRY, Administrative Patent Judges.                                   
            BARRY, Administrative Patent Judge.                                                               


                                            DECISION ON APPEAL                                                
                   A patent examiner rejected claims 1-21.  The appellant appeals therefrom under             
            35 U.S.C. § 134(a).  We reverse.                                                                  


                                               BACKGROUND                                                     
                   The invention at issue on appeal is an anti-theft device designed to interrupt a           
            break-in by discharging pepper gas or tear gas into a vehicle to hinder an intruder.              
            (Spec. at 3.)  More specifically, a local switch 16 or a remote controller 70 is used to          
            arm the device.  When a motion detector 21 senses motion inside the vehicle, an                   
            electronic circuit 110 opens a valve 141 to discharge the gas.  (Appeal Br. at 4.)
