About the Center

The San Diego Public Library (SDPL) is an officially designated Patent and Trademark Resource Center (PTRC) that is part of a nationwide library network maintained by the U.S. Patent and Trademark Office (USPTO).

The Patent and Trademark Resource Center is located on the 3rd floor of the Central Library. You do not need to visit SDPL in-person to access search tools, but the library provides certain resources (e.g. a current collection of full-color Plant patents, and legal reference books) that are only accessible in-person.

PTRC Representatives are library staff who are information experts trained on how to use search tools to access patent and trademark information. Representatives can:

  • Demonstrate how to use search tools to conduct a patent or trademark search
  • Direct you to information and explain the application process and fee schedule
Please note: Patent searching often is a complicated process that may require the assistance of a patent attorney or patent agent. PTRC Representatives are not attorneys and cannot provide legal advice. Staff can, however, direct you to lists of local patent attorneys who are licensed to practice before the USPTO.

What is a patent?

A patent is an intellectual property right granted by the Government of the United States of America to an inventor “to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States” for a limited time in exchange for public disclosure of the invention when the patent is granted.
 
This right was established over 200 years ago in Article 1, Section 8 of the United States Constitution: “To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.”

What Is a Trademark or Servicemark?

A trademark is a word, phrase, symbol or design, or a combination of words, phrases, symbols or designs, that identifies and distinguishes the source of the goods of one party from those of others.
 
A service mark is the same as a trademark, except that it identifies and distinguishes the source of a service rather than a product. Throughout this guide, the terms "trademark" and "mark" refer to both trademarks and service marks.

Business Names

What is a business name?
Before you can register your business name, it is important to determine your business entity or structure. A business entity is an ownership structure that impacts how the business is taxed, financed, owned, managed, run, and also protected by insurance. The California Secretary of State recommends that you consult a private attorney and tax accountant for guidance on determining the best entity type for your situation. A business entity can be formed in California by registering the entity through the Secretary of State.
For more information, visit the California Secretary of State website.
 
What is a fictitious business name?
If you plan to sell your products or services under a name that is not your official registered business name, you must file a Fictitious Business Name Statement with the Recorder/County Clerk within 40 days of your first transacting business.
For more information, visit the San Diego Assessor/Recorder/County Clerk website.
 
What is a domain name?
A domain name is the web address or URL where users can access a specific website. You can select an accredited domain registrar through the Internet's Network Information Center (InterNIC)’s Accredited Registrar Directory.
For more information, visit the InterNIC website.
