  We study the discovery potential of the CMS detector for the scalar
leptoquark pair production at the LHC. Present and future exclusion limits are
considered. We find that the maximal leptoquark mass reach is about 1.47 TeV
for the branching ratio of Br(LQ_l -> l q)=100 %, while for Br(LQ_l -> l q)=50
% the upper limit is 1.2 TeV for an integrated luminosity of 100 fb-1. We
obtain comparable results for electron and muon-type leptoquarks. The pileup
effect at high luminosity is discussed.
