Patent and Trademark Services

The Sunnyvale Library is a Patent and Trademark Depository Library (PTDL). Supported by a US Patent and Trademark Office (USPTO) program and expert staff, PTDLs are the primary personalized channel for the distribution of patent and trademark information to the public. Annual week long training seminars at the USPTO provide Sunnyvale librarians with the most current patent and trademark information.

As a PTDL, Sunnyvale Public Library offers:

* Free access to patent and trademark documents in various formats including through the USPTO Web site, CD-ROM DVD-ROM, and paper
* Patent searching guides and other reference materials on intellectual property
* USPTO-trained staff to answer patent and trademark questions and the ability to request assistance from USPTO experts for obtaining information if further support is needed.

Whether you are researching a new invention or technology, learning about the patents of a particular company, or looking for a patent of a friend or relative, the Sunnyvale Library PTDL has the resources you need. Please note that librarians may not provide legal advice.
