change its mount completely, introducing the EOS 600-series a few years later, breaking compatibility with the former FL and FD lens mounts. Canon's EOS system was the only fully electronic lens mount system, with no mechanical connections between camera body and lens: the autofocus motors were housed in the lens itself, rather than the camera body. Legal troubles Early Maxxum 7000 cameras were inscribed "MAXXUM 7000" with a crossed 'XX'. The oil giant Exxon considered this to be a violation of its trademark, because the XX in its logo was linked in a similar fashion. As a result, Minolta was allowed to distribute cameras that were already produced, but was forced to change the stylistic XX in Maxxum and implement this change in new production. All Maxxum cameras produced thereafter had a regularly scripted double 'X'. Minolta's autofocus design was found to infringe the patents of Honeywell, a U.S. corporation. After protracted litigation, Minolta in 1991 was ordered to pay Honeywell damages, penalties, trial costs and other expenses in a final amount of $127.6 million.
