Open the CIPO recordAbstract From the Canadian patent
There is provided a blanket constructed of a woven rectangular panel with an upper portion for covering the user's torso and with a lower portion for covering the user's feet. The filler yarn is thicker in the lower portion than in the upper portion and the weave is also more dense in the lower portion. Thus the feet of the user will be better insulated than the user's torso.

Why it's free to use
- Filed December 12, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 12, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 12, 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.
