Open the CIPO recordAbstract From the Canadian patent
An electric razor with a fan assembly installed under and coaxially with a rotary inner cutter. The whiskers entering through slits of an outer cutter are cut by the inner and outer cutters, and the sheared whiskers are blown by the fans of the fan assembly and collected in a receptacle element provided in the razor. Thus, the shaving debris does not stick to the inner and outer cutters, making it easy to clean the razor.

Why it's free to use
- Filed December 16, 1993 and granted August 31, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 16, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 16, 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.
