Open the CIPO recordAbstract From the Canadian patent
A shoe, particularly for skating, includes a soft upper below which a sole for walking is rigidly coupled. The shoe has, at the lower surface of the sole and longitudinally thereto, a seat for a rigid plate having temporary engagement member for a grip member associated with a supporting frame for in-line wheels. A rigid cuff is associated with the upper, oscillates transversely and longitudinally with respect to the upper and cooperates, with an element for limiting and controlling the oscillation which is associated with the supporting frame for the in-line wheels. It is thus possible to use the shoe both for ordinary walking and for skating.

Why it's free to use
- Filed April 1, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 1, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
