Abstract From the Canadian patent

The side extension of the invention includes first and second extension wall portions each circumscribing one-half of the area defined by the upstanding walls of the wagon body. The side extensions have a groove which is engaged by a lip extending from and disposed substantially perpendicular to the upstanding walls. The first and second extension wall portions have coupling elements formed at each end thereof which are secured to one another by bolts to lock the side extension on the wagon. The side extension when mounted on the wagon extends beyond the upstanding walls of the wagon body to increase the depth of the passenger department.

Why it's free to use

  • Filed February 26, 1990 and granted October 12, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 26, 2010.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 26, 2012.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
