Open the CIPO recordAbstract From the Canadian patent
A panty brief is made by flat knitting a front piece (1) and a back piece (1') in which the leg openings (8, 9) are formed at a marginal edge zone (6) at the bottom of the penty brief. The leg openings may in a simple way obtain such a width that they do not cause local compressive press on a user. Such a great width in the leg openings (8 9) is obtained by the marginal edge zone (6) being partially made of soluble yarn (8) for forming larger stitches (19 20) and thereby a looser structure in the marginal edge zone after the dissolution of the yarn.

Why it's free to use
- Filed May 13, 1993 and granted August 26, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 13, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 13, 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.
