Open the CIPO recordNo Claude kit for weapons

Why it's free to use
- Granted July 26, 1977. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended July 26, 1994.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
