No 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.

Listed from its CIPO record in Patent Yard's archive of Canadian patents past their term. Its claims, description and drawings are in the CIPO record and on Google Patents.

Why it's free to use

  • Granted October 5, 1965. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended October 5, 1982.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
