There was actually a pretty interesting trademark litigation that came out of that, in which, if memory serves, the district court judge, after saying he really wasn't very interested in trademark law, and could basically care less, ruled against ML in his quest to continue to use his name professionally after it was purchased as part of the acquisition of the ML company. On appeal, after the 2d Circuit excoriated the district judge for his attitude toward his job, the appeals court allowed ML to continue to use his name, although not as a 'brand' (e.g. 'Cello by Mark Levinson'). Anybody with access to Lexis can find this, it was a published decision.
