Abstract From the Canadian patent

The invention relates to a method and an apparatus for decommissioning faulty doors or faulty moving treadboards on a train. To simplify and speed up decommissioning, the occurrence of a fault in a door controller prompts the faulty door to be decommissioned by remote control by the central monitoring of the doors, either directly or indirectly via the controller for an associated, non-faulty door.

Why it's free to use

  • Filed July 31, 2006 and granted January 20, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 31, 2026.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
