Open the CIPO recordNo Claude kit for weapons

Why it's free to use
- Granted June 3, 1969. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended June 3, 1986.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
