No Claude kit for weapons

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 July 28, 1931. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended July 28, 1948.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
