The broadest MTH patent on speed control would be extremely unlikely to be held valid under current patent law, and in any case is set to expire this year.

There is a narrower patent expiring in 2026 that might have a better chance of being valid, though still questionable. However, that patent only covers a system with two-way communication through the track power signal.
