Disclaimer
Plain-language disclaimer for Patent Yard. See also Terms of use · Privacy.
Patent Yard is not a law firm, is not affiliated with the United States Patent and Trademark Office, and does not give legal advice. "Lapsed" means the USPTO published an expiration notice for an unpaid maintenance fee. "Expired, full term" means the patent's 20-year term, counted from its filing date, has ended. "Likely abandoned" is our inference from USPTO records. None of these guarantees that you are free to make a particular product, since other patents may apply. Talk to a registered patent attorney or agent before investing significant money or filing a nonprovisional application.
