Fact Sheet
National Library of Medicine Trademarks


USE OF THE TRADEMARK SYMBOL (from "Basic Facts About Trademarks," published by the Patent and Trademark Office, U.S. Department of Commerce): "Once a Federal registration is issued, the registrant may give notice of registration by using the registration symbol ®, or the phrase 'Registered in U.S. Patent and Trademark Office' or 'Reg. U.S. Pat. & Tm. Off.' Although registration symbols may not be lawfully used prior to registration, many trademark owners use a TM or SM (if the mark identifies a service) symbol to indicate a claim of ownership, even if no Federal trademark application is pending."

The names listed below are registered trademarks or pending registrations for NLM. The trademark should be used when any of the names listed below are used in a document. It is only necessary to use the mark the first time the work is mentioned. If the word is part of the title, it is then only necessary to use it in the title.
