An interesting three-lepton decay mode of the proton is analyzed in a fractionally-charged-quark SU(4)/sub c/ x SU(2)/sub L/ x SU(2) /sub R/ Pati-Salam-type model. With a quark-lepton-unification mass of about 10/sup 5/ GeV and reasonable values for the colored-Higgs-boson masses, the lifetime of the proton turns out to be of the order of 10/sup 31/ yr. This, being comparable with the results of the lifetime calculation for other decay modes, should not be ignored in the dedicated experiments.
