Open the CIPO recordAbstract From the Canadian patent
The watch case (1) is of plastic material and provided with a hole (3) in which a push button (6) may slide. The end (12) of the stem (7) of the push button includes a bulge (13) the diameter of which is greater than that of the neck (11) formed at the end of the hole opening into the interior of the case (1). When the stem (7) is introduced into the hole (3) of the wall (2) the bulge (13) elastically deforms the neck (11) which afterwards reassumes its initial form and assures axial positioning of the stem (7).

Why it's free to use
- Filed April 11, 1990 and granted July 20, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 11, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 11, 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.
