In three years of observations the Large Area Telescope (LAT) on board the Fermi Gamma Ray Space Telescope has observed high-energy γ-ray emission from 35 gamma-ray bursts (GRBs). The first Fermi-LAT catalog of GRBs is in preparation within the Fermi LAT collaboration and will provide a systematic study of high-energy emission from GRBs. In this paper we present some of the main results, briefly discussing durations, energetics, time-resolved and time integrated LAT spectral analysis. We also discuss characteristics of LAT-detected emission such as its delayed onset and longer duration compared to emission detected by the GBM, and its power-law temporal decay at late times.
