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.

A slingshot is provided and consists of a forked handle a missile receiving pouch and resilient members connecting the pouch to the handle whereby the resilient members are solid cylindrical rubber tubes to improve operating efficiency of the slingshot. In a modification the forked handle is angularly adjustable for greater accuracy.

Why it's free to use

  • Granted October 1, 1991. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended October 1, 2008.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
