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.
Read the whole patent
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 May 20, 1935. Even if it was granted, its term would have ended by May 20, 1956.
- A pharmaceutical extension adds at most five years, so even that would have ended by May 20, 1961.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
