Open the CIPO recordAbstract From the Canadian patent
This belt has a generally flexible portion in which several compressible wells are formed. The flexible portion is located over the back of the person wearing it around the chest. A plurality of upstanding substantially resilient semi-rigid stems are provided in the wells. The stems have a height slightly lower than the depth of the wells. When the person sleeps on the back, the weight of the body would compress the wells such that the semi-rigid stems will protrude outside of the wells to cause irritation to the back of the wearer so that the person would subconsciously turn to sleep on the side or stomach thus detering snoring to occur.

Why it's free to use
- Filed March 14, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 14, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 14, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
