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.

Why it's free to use

  • Granted March 16, 1920. A patent granted before 1976 lasted at most 17 years from grant, so its term ended by March 16, 1937.
  • We check US rights only. Old patents can still inspire new ones: improvements may be patentable.
