California intellectual property law combines federal protections for patents, copyrights, and trademarks with state statutes covering trade secrets, the right of publicity, state trademarks, and fine art preservation. Owners can win injunctions, actual damages, and in many categories enhanced or exemplary damages of two to three times the base award. Serious counterfeiting, piracy, and trade secret theft can also bring felony charges, prison time, and fines reaching seven figures.
Because so much of the state’s economy runs on software, entertainment, biotech, and consumer brands, these rules touch a large share of California workers and businesses. Here is how the main categories work, what you can recover, and how long you have to file.
What California Protects
Intellectual property falls into a few distinct legal regimes, and the remedies depend on which one applies to your situation.
- Trademarks — names, logos, and slogans that identify goods and services. Protected federally, at the state level, and under common law.
- Patents — inventions, protected exclusively by federal law.
- Copyrights — original creative works, protected federally, with California adding narrow protections for fine art.
- Trade secrets — confidential business information, protected under California’s Uniform Trade Secrets Act.
- Right of publicity — a person’s name, voice, image, and likeness, protected by California statute.
Patents are entirely federal. California courts do not decide whether a patent is valid, though they routinely handle related licensing and contract disputes involving patented technology. For everything else, state law adds meaningful tools on top of the federal baseline.
Trademarks
A trademark is any name, logo, slogan, or other identifier that distinguishes one company’s goods or services from another’s. California businesses can register federally with the United States Patent and Trademark Office or at the state level with the California Secretary of State under the Model State Trademark Law, found in Business and Professions Code Chapter 2, Division 6.1California Secretary of State. Trademarks and Service Marks Federal registration gives nationwide protection; state registration covers use within California. Even without registering, California recognizes common law trademark rights for marks that have been used in commerce long enough to develop distinctiveness.
Infringement happens when someone uses a mark that is identical or confusingly similar to an existing one in a way that could mislead consumers. Business and Professions Code 14245 lets the owner of a registered mark sue when another party uses a reproduction or imitation in connection with selling goods or services where confusion is likely.2California Legislative Information. California Business and Professions Code 14245 – Infringement The statute also creates liability for landlords and property owners who knowingly allow infringing sales on their premises.
Courts can order an infringer to stop using the mark immediately. On damages, Business and Professions Code 14250 allows the trademark owner to recover up to three times the infringer’s profits and up to three times the actual damages suffered.3California Legislative Information. California Business and Professions Code 14250 – Violations That treble-damages provision gives real teeth to state trademark enforcement.
Copyrights and Fair Use
Copyright protects original creative works such as books, music, films, software, and visual art. Protection attaches automatically when a work is fixed in a tangible form, though registering with the U.S. Copyright Office unlocks additional remedies in court. The Central District of California, covering Los Angeles, is one of the busiest copyright litigation venues in the country.
A copyright holder can sue for unauthorized copying, distribution, or public performance. If the work was registered before the infringement began, the holder can elect statutory damages instead of proving actual losses. Statutory damages run from $750 to $30,000 per work, and the ceiling climbs to $150,000 per work when infringement was willful.4Office of the Law Revision Counsel. 17 USC 504 – Remedies for Infringement: Damages and Profits Courts routinely issue injunctions to halt ongoing infringement.
Not every unauthorized use is infringement. Federal law recognizes a fair use defense, and courts weigh four factors together: the purpose and character of the use (with transformative uses like criticism, commentary, parody, and news reporting favored); the nature of the original work; the amount used; and the effect on the market for the original.5Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use No single factor decides the question, and the analysis is fact-intensive, so similar-looking situations can produce opposite outcomes.
The California Art Preservation Act
California gives visual artists a shield federal copyright does not. Civil Code 987 prohibits anyone other than the artist who owns the work from intentionally defacing, altering, or destroying a work of “fine art,” defined as an original painting, sculpture, drawing, or glass work of recognized quality.6California Legislative Information. California Civil Code 987 – Preservation of Works of Art Professionals who frame, conserve, or restore fine art are also liable if their negligence damages the piece. Artists can seek injunctive relief, actual damages, and punitive damages.
Trade Secrets
Trade secrets cover confidential business information that derives value from being kept secret, including formulas, algorithms, customer lists, and proprietary processes. Unlike patents, trade secrets need no registration. The tradeoff is that the owner must take reasonable steps to keep the information confidential; once it becomes public, the protection is gone.
California’s Uniform Trade Secrets Act, starting at Civil Code 3426.1, defines a trade secret as information that derives independent economic value from not being generally known and is the subject of reasonable efforts to keep it confidential.7California Legislative Information. California Civil Code 3426.1 Misappropriation includes acquiring a trade secret through improper means, or disclosing one when you knew it was obtained improperly or under circumstances creating a duty of confidentiality.
A plaintiff who proves misappropriation can recover actual losses plus the infringer’s unjust enrichment. If neither figure is provable, the court can order a reasonable royalty. When the misappropriation was willful and malicious, exemplary damages up to twice the compensatory award are available.8California Legislative Information. California Civil Code 3426.3
Right of Publicity
California’s right of publicity matters in a state full of entertainers, athletes, and public figures. Civil Code 3344 makes it illegal to knowingly use another person’s name, voice, signature, photograph, or likeness for commercial purposes without consent.9California Legislative Information. California Civil Code 3344 – Use of Anothers Name, Voice, Signature, Photograph, or Likeness
Damages start at a $750 floor, but the injured person can recover actual damages and any profits from the unauthorized use if those numbers are higher. Punitive damages are also available, and the prevailing party recovers attorney’s fees and costs. Courts can issue injunctions requiring removal or recall of the infringing material within two business days of the order. With the rise of AI-generated content, this statute is increasingly relevant to synthetic media that mimics real people.
Who Owns IP Created at Work
Much of California’s intellectual property is created by employees, and the rules that decide ownership diverge from other states in a few important ways.
Work Made for Hire
Under federal copyright law, when an employee creates a work within the scope of their job, the employer owns the copyright automatically. For independent contractors, the rules are stricter. A commissioned work only qualifies as “work made for hire” if it falls into one of nine specific categories, such as contributions to a collective work, translations, or parts of a motion picture, and both parties sign a written agreement saying so.10U.S. Copyright Office. Works Made for Hire If those requirements are not met, the creator owns the copyright regardless of who paid for the work.
Employee Inventions
Many California employment contracts require workers to assign all inventions to the employer. Labor Code 2870 limits how far these clauses can reach. An employer cannot claim ownership of an invention that the employee developed entirely on their own time, without using any company equipment or trade secret information, unless the invention relates to the employer’s current or anticipated business or resulted from work the employee did for the employer.11California Legislative Information. California Labor Code 2870 Any contract provision that tries to grab inventions beyond those boundaries is unenforceable as against public policy.
The Non-Compete Ban
California flatly prohibits non-compete agreements. Business and Professions Code 16600 declares that any contract restraining someone from engaging in a lawful profession, trade, or business is void.12California Legislative Information. California Business and Professions Code 16600 Courts read the statute broadly and invalidate non-competes no matter how narrowly written.
Legislation effective in 2024 strengthened this ban. Under Business and Professions Code 16600.5, a non-compete signed in another state is still unenforceable if the employee works in California, and employers who attempt to enforce a void non-compete commit a civil violation. Employees can sue for injunctive relief, actual damages, and attorney’s fees.13California Legislative Information. SB 699 – Noncompete Agreements The ban makes trade secret protection especially important for California employers, since they cannot rely on non-competes to keep departing employees away from competitors.
Civil Remedies
When IP rights are violated, California courts have a wide toolkit. Compensatory damages cover actual financial losses, including lost profits and the infringer’s unjust enrichment. For state trademark infringement, the court can award up to three times the infringer’s profits and three times the trademark owner’s damages.3California Legislative Information. California Business and Professions Code 14250 – Violations For trade secret misappropriation, exemplary damages up to twice the compensatory award are available when the conduct was willful and malicious.8California Legislative Information. California Civil Code 3426.3
Injunctive relief is often more valuable than money. Courts can order an infringer to stop using the protected material immediately, and violating an injunction can bring contempt charges. In high-stakes trade secret disputes, courts also issue temporary restraining orders to prevent confidential information from spreading while a case is pending.
Attorney’s fees are recoverable in several contexts. Under the Lanham Act, federal courts can award fees to the prevailing party in “exceptional” trademark cases.14Office of the Law Revision Counsel. 15 USC 1117 – Recovery for Violation of Rights Under the Copyright Act, courts have discretion to award reasonable attorney’s fees to any prevailing party.15Office of the Law Revision Counsel. 17 USC 505 – Remedies for Infringement: Costs and Attorneys Fees
Criminal Penalties
IP violations cross into criminal territory when they involve large-scale counterfeiting, piracy, or trade secret theft committed with fraudulent intent. California prosecutors bring these cases regularly.
Counterfeiting
Penal Code 350 covers manufacturing, selling, or knowingly possessing for sale counterfeit trademarked goods. The penalties depend on both the number of items and their total value.16California Legislative Information. California Penal Code 350 – Counterfeit Marks For fewer than 1,000 items with a combined value under $950 (the grand theft threshold), the offense is a misdemeanor with up to one year in county jail and fines up to $10,000 for individuals or $200,000 for business entities.17California Legislative Information. California Penal Code 487 – Grand Theft At 1,000 items or more, or $950 or more in combined value, it becomes a wobbler; felony sentences run 16 months, two years, or three years, with fines up to $500,000 for individuals and $1,000,000 for businesses.
A subsequent conviction on the lower-tier offense also becomes a wobbler, with individual fines climbing to $100,000. If counterfeit goods directly cause death or serious injury, penalties jump to two, three, or four years in prison and fines up to $100,000.
Recording Piracy
Penal Code 653h targets unauthorized copying and distribution of audio and video recordings. When the offense involves 1,000 or more pirated copies, it becomes a felony punishable by two, three, or five years in prison and fines up to $500,000.18California Legislative Information. California Penal Code 653h – Unauthorized Recordings Smaller violations involving at least 100 copies carry misdemeanor penalties of up to one year in jail and fines up to $20,000.
Trade Secret Theft
Penal Code 499c criminalizes stealing, fraudulently taking, or copying a trade secret with intent to deprive the owner of control or to use the information for personal or third-party benefit. Conviction is punishable by up to one year in county jail, or 16 months to three years in state prison, along with fines up to $5,000.19California Legislative Information. California Penal Code 499c – Theft of Trade Secret The statute also covers bribing an employee to hand over proprietary information, with the same penalties for both the person offering the bribe and the employee who accepts it.
Deadlines for Filing
Missing a filing deadline can kill an otherwise strong IP claim. The time limits vary by category, and they do not all start the same way.
For trade secrets, you have three years from the date you discovered or reasonably should have discovered the misappropriation. A continuing misappropriation counts as a single claim, so the clock runs from the initial discovery rather than from each subsequent use.20California Legislative Information. California Civil Code 3426.6
For state trademark claims, California applies a four-year limit. Courts may also apply the doctrine of laches, which can bar even timely claims if the plaintiff unreasonably delayed and the delay prejudiced the defendant.
For copyrights, the deadline is three years after the claim accrues.21Office of the Law Revision Counsel. 17 USC 507 – Limitations on Actions Under the separate-accrual rule, each new infringing act starts its own three-year window, but damages are limited to the three years before the lawsuit was filed. The Supreme Court confirmed this backward-looking damages cap in Petrella v. Metro-Goldwyn-Mayer, Inc., holding that a plaintiff who delays can still sue but can only collect for recent infringement.22Justia. Petrella v. Metro-Goldwyn-Mayer Inc.
For patents, no damages can be recovered for infringement committed more than six years before the lawsuit was filed.23Office of the Law Revision Counsel. 35 USC 286 – Time Limitation on Damages That functions as both a practical filing deadline and a damages cutoff.
Early detection and prompt action matter. The longer you wait to enforce your rights, the weaker your position becomes, and at some point the courthouse door closes entirely.
