Understanding the Patent and Trademark Depository Library

Definition & Meaning

A Patent and Trademark Depository Library (PTDL) is a library designated by the United States Patent and Trademark Office (USPTO) to provide access to patent and trademark resources. These libraries receive copies of patents, CD-ROMs containing registered and pending trademarks, and other related materials. Users can access these resources for free, and the libraries actively promote and disseminate information about patents and trademarks. Additionally, PTDLs offer internet access to the USPTO's online collections, enhancing the availability of vital information for inventors and businesses.
