Abstract Results are presented for searches for leptoquark pair production using 1.8 - 5.0 fb-1 of proton-proton collision data at sqrt(s) = 7TeV collected by the CMS detector at the LHC. First- and second-generation scalar leptoquarks are searched for in final states with either two leptons and two jets or one lepton, missing transverse energy, and two jets. Third-generation leptoquarks are searched for in the final state with two b-tagged jets and large missing transverse energy. No significant excess beyond the standard model predictions is found and 95% confidence level upper limits are set on the scalar leptoquark pair production cross section in each channel. Limits are calculated for a range of leptoquark mass and for a variable branching fraction of the leptoquark to a charge lepton and a quark. These limits are the most stringent to date.
