Open the CIPO recordNo Claude kit for weapons
Claude doesn't help design weapons, ammunition or explosives, so this page has no Reinvent kit. To develop this one, work with a federally licensed manufacturer (many of these items are regulated) and a registered patent attorney or agent, listed on the USPTO roster.
Abstract From the Canadian patent

Why it's free to use
- Filed April 2, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 2, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 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.
