Abstract From the Canadian patent

It is constituted on the basis of a tongue (1) which is conveniently attached to the boot which is divided into a number of sectors (3) in which are some receptacles (5) which hold sheets (6) of material resistant to impact and ductile in order to facilitate the adaptation thereof to the form of the boot when closed. The sectors (3) are delimited by some lines of stitching (4) which facilitate the relative inclination between sectors (3) and therefore the articulation of the tongue (1) when the boot is flexed achieving greater user comfort.

Why it's free to use

  • Filed October 5, 2004 and granted September 11, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 5, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 5, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
