Han ansökte i december 1871 om patent men eftersom han inte hade tillräckligt med pengar att betala patenavgiften rann det hela ut i sanden. Bell konstruerade en telefon som han tog patent på den 14 februari 1876. År 1877 kunde man inhandla ett par importerade telefoner av fabrikat Bell på firmorna Numa Pettersson och Joseph Leja i Stockholm.
