At what point in time does the copyright lapse on any of the Middle-earth based tales?

In theory 75 years after Tolkien's death.

However, recent editions of LotR (& other works) are copyright to the Tolkien Trust, not JRRT himself, so I'm not sure how long the copyright in this case will hold for. It will outlast me at least, for which I'm grateful.
