Its specification, documents and status are on IP Australia's AusPat.
Open the AusPat 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.

Why it's free to use
- Filed May 25, 1988 and granted September 25, 1990. 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 May 25, 2009.
- A pharmaceutical extension adds at most five years, so even that would have ended by May 25, 2014.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
