We present results from our analysis of a deep XMM-Newton observation of the supernova remnant IC 443. This observation consists of six segments which cover the entire remnant. Images produced from these observations show many point-like and compact diffuse sources within the field of view. Most of these sources have not previously been associated with any class of astrophysical objects. Here we show preliminary results of our effort to identify some of these sources using their multiwavelength spectra and morphology. Taking into account not only positional agreement but also plausible source emission mechanisms, we then discuss the possibility that one of these sources may be responsible for the >100 MeV gamma-ray emission observed from the EGRET unidentified source 3EG J0617+2238.
