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 December 10, 1987 and granted December 14, 2000. An Australian standard patent lasts 20 years from its date of patent, which is at most a year after this filing, so its term ended by December 10, 2008.
  • A pharmaceutical extension adds at most five years, so even that would have ended by December 10, 2013.
  • We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
