There are gobs of LIM and LSM patents out there, and I don't think Intamin or Vekoma have any of them. Vekoma has been developing LSM technology for amusement rides (in fact, Intamin's
Superman: The Escape uses motors licensed from Vekoma), Intamin and Premier have both been using LIMs. Premier's LIMs have come from Force Engineering (
http://www.force.co.uk ) although some Force LIMs have been replaced with PSM units. It's these LIM builders who have the patents, not the ride builders. And if B&M wanted to do a LIM launch, I'm sure Force or PSM or any of a handful of other companies would be willing to provide the motors.
