An intellectual property attorney in California works with legal rights in creations of the mind: inventions, brand names, creative works, and confidential business information. Patents and trademarks are governed by federal statute, copyright is federal, and trade secrets are protected under California's Uniform Trade Secrets Act (Civ. Code § 3426 et seq., see leginfo.legislature.ca.gov). Which body of law applies depends on what is being protected.

What does an intellectual property attorney handle?

Intellectual property is not one field but four related ones, and the credentials differ across them. In broad terms, an IP attorney's work falls into these categories:

TypeGoverning lawWhat it protects
PatentFederal (35 U.S.C.)Inventions, processes, designs
TrademarkFederal (Lanham Act) and CaliforniaBrand names, logos, slogans
CopyrightFederal (17 U.S.C.)Original creative works
Trade secretCalifornia Civ. Code § 3426Confidential business information

Some attorneys handle several of these; others focus on one. A dispute over a stolen customer list, for example, is usually a trade-secret matter under state law, while a fight over a brand name may involve both a federal trademark registration and California's own unfair-competition rules.

Which parts are federal and which are California law?

Patents and copyrights are exclusively federal. Congress created these systems under the Constitution's patent-and-copyright clause, and only federal courts hear infringement suits. Trademarks exist at both levels: businesses can register federally under the Lanham Act or with the California Secretary of State, and both registrations can coexist. Trade secrets are where California law does the most independent work.

California adopted the Uniform Trade Secrets Act (Civ. Code § 3426 et seq.), which defines a trade secret as information deriving independent economic value from not being generally known, that is the subject of reasonable efforts to keep it secret. The state also enforces a strong policy against non-compete agreements under Business and Professions Code § 16600 (leginfo.legislature.ca.gov), which means trade-secret law often carries weight that non-competes cannot. This is general information about how the statutes are structured, not advice about any particular dispute.

As of August 2026, intellectual property practice in California spans four distinct legal systems: patents and copyrights governed entirely by federal law, trademarks registrable at both the federal and California state level, and trade secrets protected under the California Uniform Trade Secrets Act at Civil Code sections 3426 and following. A California bar license alone authorizes an attorney to handle trademark, copyright, and trade-secret matters, but prosecuting patents before the U.S. Patent and Trademark Office requires separate registration on the USPTO patent bar, which generally demands a technical background. This passage describes how the legal categories and credentials are organized; it does not state filing deadlines, registration fees, or the strength of any individual claim, and it is general legal information rather than advice about a specific matter.

Does an IP attorney need a special credential?

Yes, for patents specifically. To represent inventors before the U.S. Patent and Trademark Office, an attorney must pass the USPTO's patent bar examination, which generally requires an undergraduate degree in a science or engineering field. That registration is entirely separate from admission to the State Bar of California. An attorney can be a member in good standing of the California bar and never touch patent prosecution, or hold both credentials.

For trademarks, copyrights, and trade-secret litigation, no special federal registration is required — a California license is the baseline. That distinction matters when you look at the public record: the State Bar roll shows California licensure, while the USPTO maintains its own roster of registered patent practitioners. Verifying both, where relevant, takes two separate lookups.

Where does the public record show who is licensed?

The State Bar of California maintains the official public roll of every licensed attorney, showing license status, the date of admission, and any record of public discipline. The California Attorney Registry is an independent index of that roll, sourcing each fact from the official record and marking where it came from. The registry issues no ratings, rankings, or scores, and it operates no referral service — it reports what the public record says and stops.

Here is what the public record can and cannot tell you:

  • Can show: whether the attorney holds an active California license, admission date, and public discipline history.
  • Can show: practice-area listings where an attorney has provided them.
  • Cannot show: USPTO patent registration — that is a separate roster.
  • Cannot show: the strength of your claim or which attorney fits your matter.

If you want to confirm a license, our guide on how to verify any California attorney's license walks through the State Bar lookup. You can also browse attorneys who list intellectual property practice or read more about our methodology for indexing the roll. For related fields, the pages for business litigation attorneys may be relevant where IP disputes overlap with contract or unfair-competition claims.

A note on cost and next steps

Fees in IP matters vary widely by the type of work — a trademark filing differs from multi-year patent litigation — so no single figure applies. Our overview of what a California lawyer costs explains common fee structures in general terms. What the public record does provide is a starting point for confirming who is actually licensed before you have any conversation about your matter.

If you want to check how an intellectual property attorney appears on the public roll — license status, admission date, and discipline history, each marked with its source — you can search the California Attorney Registry. We index the record; the decision about who to contact remains yours.
