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 IP Australia record in Patent Yard's archive of Australian patents past their term. Its claims, description and drawings are in the AusPat record and on Google Patents.

Why it's free to use

  • Filed July 12, 1945. Even if it was granted, its term would have ended by July 12, 1966.
  • A pharmaceutical extension adds at most five years, so even that would have ended by July 12, 1971.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
