Why it's free to use
- Granted September 16, 1980. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended September 16, 1997.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
