Overview
The published document from the EPO: abstract, claims, description and drawings. Open it full size
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 EPO record in Patent Yard's archive of European patents past their term. Its claims, description and drawings are in the EPO PDF and on Google Patents.
Why it's free to use
- Filed August 12, 1980 and granted November 21, 1984. A European patent lasts at most 20 years from filing, so its term ended August 12, 2000.
- A supplementary protection certificate, which can extend a medicine or crop-protection patent, adds at most five and a half years, so even that would have ended by February 12, 2006.
- We check European rights only. A US or other national patent in its family could still be in force: check its family on Espacenet or Google Patents.
