Copyright Basics for California Creators
Copyright is purely federal — registered with the U.S. Copyright Office, enforced through federal district courts. California infringement cases are filed in U.S. District Courts for the Northern.
Fair Use of Copyrighted Material in California
California creators using copyrighted material need fair-use analysis — four-factor test (purpose, nature, amount, market effect) determines whether use is lawful without permission.
Patents Overview for California Inventors
Patents are entirely federal — granted by the USPTO and litigated in federal district court. California infringement actions are filed in U.S. District Courts for the Northern.
Trademark Registration in California
Trademark protection in California comes from THREE sources: federal registration with the USPTO, state registration with the California Secretary of State (~$70, every 5 years), and common-law rights from actual use.
Trade Secret Protection in California
California trade secrets are protected under both state Uniform Trade Secrets Act (UTSA) and federal Defend Trade Secrets Act (DTSA, 2016). No registration required — but reasonable secrecy efforts are.

Do I need a lawyer to file a trademark?

Patent, trademark or copyright — which do I need?

Patents protect inventions, trademarks protect brand names and logos, and copyrights protect creative works like writing, art and software.
