In reference to the patent: US1434590

Can I re-invent this somehow? I thought it was an old antique metal ring back in the 1800's. What is the deal with this patent?

  • Welcome to Ask Patents. I'm unsure of what you're trying to ask here. I understand you have some questions about the listed patent, but are you curious of the status of the patent (expired/not expired), what it covered, whether you could re-patent it, or something else? I would appreciate if you could edit your question a bit to be a little more specific. Please let me know if I can help with that process. – Matthew Haugen Jun 5 '16 at 18:22
  • exactly what you said yes, the status expirer etc what it covers, yes all that would be good info thank you. – joe Jun 5 '16 at 18:24
  • Does it simplify your question to know that it is expired? See "How do you determine a patent expiration date?" – Matthew Haugen Jun 5 '16 at 18:27
  • We definitely want to get your questions all answered; I'm just asking in case this all ultimately boils down to concern over infringing. – Matthew Haugen Jun 5 '16 at 18:29
  • ok i don't really know what infinging means sorry, but the post above .... what did you mean by 'it is expired' does this mean it hasnt got a patent anymore ? – joe Jun 5 '16 at 18:31
