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.”

As a Patent and Trademark Resource Center, the Central Library provides access to the Public Examiner's Automated Search Tool (PubEAST), a powerful database that allows for sophisticated search queries, simultaneous searching of the USPTO, EPO abstracts, and JPO abstracts. Whereas PatFT, the search engine on the USPTO's website, is only keyword searchable back to 1976, PubEAST's OCR backfile allows keyword searching between 1920 and 1975. PubEAST also allows users to download patent data in spreadsheet format and to save search query histories.
is available for use at the Central Library
Monday through Friday during regular operating hours. There are two (2) dedicated public computers on the 3rd Floor to use in searching PubEAST

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.

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.
