A search for pair-production of first generation scalar leptoquarks is performed in the final state containing an electron, a neutrino, and at least two jets using proton¨Cproton collision data at . The data were collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 36 pblns="""">?. The number of observed events is in good agreement with the predictions for standard model processes. Prior CMS results in the dielectron channel are combined with this electron + neutrino search. A 95 % confidence level combined lower limit is set on the mass of a first generation scalar leptoquark at 339 GeV for , where lns="""">¦Â is the branching fraction of the leptoquark to an electron and a quark. These results represent the most stringent direct limits to date for values of lns="""">¦Â greater than 0.05.
