I read up on this profusely (especially WSJ when it was a vastly better publication than today) around the time (before & after) the "Mickey Mouse Protection Act" (1998) was being passed.
Although every passing year (in perpetuity) more individual Disney films, etc. will become "public domain," Disney owns the trademarks forever, and no one else can make a Mickey, etc. if people can easily be led to believe it was made by Disney.
Hence all the horror films with Mickey, Pooh, etc. That's safe.
However, I remember also reading that this was with the expectation Disney consistently "uses" their Trademark (if you don't use it, you
can lose it!)
For example, it was not long after the legislation passed I noticed Mickey a lot more often on TV: Mouse Works, House of Mouse, Clubhouse, Racers, Paul Rudish,, etc. Whereas not long before Disney didn't even show him in a 1993 Bonkers episode
about Mickey. Arguably from one extreme to the next.
Nevermind all the other Mickey offerings "through the 'ears" (sorry couldn't resist!),.
Today is a far cry from when Mickey was
mostly found either in a parade or if you were in the right place/right time for a "meet & greet" (especially between when MMR closed in 1980, and 1988 when Birthdayland opened).
If anyone "pushes back" on this (or if I get time) I'll try to re-pull my sources.
