Open the CIPO recordAbstract From the Canadian patent
An undergarment comprising front and rear bodies placed one upon another and welded together only at the crotch zone along a welding line convexly curved upward. The undergarment is partially cut away at laterally opposite sides to form leg-openings so as to leave a relatively wide crotch zone and thereby to improve a fitness of the undergarment to a crotch of wearer's body.

Why it's free to use
- Filed July 21, 1993 and granted December 22, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 21, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 21, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
