How to Register a Trademark in California: Step-by-Step Guide

Protecting your business name, logo, or slogan through a trademark is one of the smartest moves you can make as a business owner in California. A registered trademark ensures that your brand identity is legally protected from misuse and confusion in the marketplace. Here’s a clear step-by-step guide to help you understand how to register a trademark in California.


Step 1: Determine Eligibility


Before filing, confirm that your mark is eligible for registration. The mark must be distinctive — meaning it identifies your business as the source of the goods or services. Generic or overly descriptive terms usually cannot be trademarked.


Step 2: Conduct a Trademark Search


A comprehensive search is essential to ensure your mark isn’t already in use. You can check both the California Secretary of State’s database and the United States Patent and Trademark Office (USPTO) database. Discovering conflicts early prevents costly rejections later.


Step 3: Choose State or Federal Registration


California allows for state-level registration through the Secretary of State, which protects your mark only within the state. Federal registration through the USPTO provides nationwide protection. Many businesses choose to pursue both, depending on their scope of operation.


Step 4: Prepare and File Your Application


For California registration, submit your application to the Secretary of State’s Trademark Unit. You’ll need:


  • A completed application form
  • A specimen showing the mark in use (such as on packaging or a website)
  • The filing fee (currently $70 per class)


For federal registration, apply online via the USPTO’s Trademark Electronic Application System (TEAS).


Step 5: Monitor and Respond


After submission, the reviewing office may contact you for clarification or corrections. Be ready to respond promptly to avoid delays or denials.


Step 6: Maintain Your Trademark


Once registered, you must continue to use your mark in commerce and renew it periodically. In California, state trademarks must be renewed every five years. For federal trademarks, renewal deadlines vary, typically every ten years.
