Said floor element comprises projections and recesses along its periphery and the profile on all peripheral sides of the basic element when seen from the center of the respective top face of the basic element is substantially the same and is substantially point- symmetric with respect to its mid-point. The inventive floor element is further characterized in that the profile consists of three projections and three recesses.

Why it's free to use

  • Filed September 26, 2001 and granted November 5, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 26, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 26, 2023.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
