It looks like MIT didn't maintain their 1789164 U.S. trademark registration number for Athena: "computer programs, and instruction manuals sold therewith, which collectively provide a set of integrated network services; namely, user authentication, file service, name service, messaging service, mail service, network management service, and print service ... Cancellation Date ... February 12, 2016"

(they do have registration number 1722642 for "Athena ... educational services; namely, courses of instruction at the college and graduate level and research services" but this doesn't look closely related)
