We propose a new variation to the SUSY Left-Right model (LRM) by extending the Minimal B-L model. Starting from energies of s√>7 TeV, we can describe an intermediate scale for Grand Unification along the Pati-Salam path from SO(10). Here the breaking of SU(2)L×SU(2)R×U(1)B−L→SU(2)L×U(1)Y is by a doublet rather than a triplet. Analyzing the RGE equations, the right handed neutral component of the doublet Lc acquires a negative mass squared at low energies. At least one generation spontaneously acquires a nonzero VEV and breaks the LRM symmetry into the MSSM. A seesaw is induced through gauge couplings maintaining light active neutrinos as well as heavy sterile neutrinos after Left-Right Breaking.
