How Can Prior Use Defense Protect You in Trademark Litigation?
Trademark litigation can be a tough battle for businesses, especially when their brand identity is challenged in court. The stakes are often high, with a business’s reputation, customer trust, and financial security hanging in the balance.

What Is Prior Use Defense in Trademark Disputes?
The prior use defense is a legal argument used by defendants facing trademark infringement lawsuits. It allows an entity to counteract a plaintiff’s claims by proving that the defendant had used the trademark in good faith for business purposes before the plaintiff registered or began using the same or similar trademark.
Under this doctrine, the prior user can establish rights to continue operating under the existing mark, provided they meet specific conditions. The defense is particularly useful for small businesses or startups that have dedicated time and resources to building their brand long before a larger company comes along and stakes a claim to the same name or logo.
Why Is Prior Use Defense Significant?
Trademark disputes often arise when a company registers a mark and later discovers that another entity has been using an identical or confusingly similar one. Without a registered trademark, defendants may initially feel at a disadvantage. However, the prior use defense allows prior users to retain access to their brand due to the timing of trademark registration.
Some of the key benefits of this defense include:
Upholding equity: The principle acknowledges the good faith efforts of a business that has been using the trademark in question, potentially for years before a plaintiff sought trademark protection.
Preserving business assets: It allows businesses to retain their long-established goodwill and customer recognition linked to their brand identity.
Challenging aggressive litigation: Large companies often leverage their financial resources to assert trademark claims. However, the prior use defense can level the playing field for smaller businesses.
California Laws Governing Prior Use Defense
California follows state and federal trademark laws, meaning businesses in the region are subject to the Lanham Act (the federal trademark law) and the applicable California state statutes. Under the Lanham Act, the prior use defense is recognized for businesses meeting specific legal thresholds.
To successfully claim a prior use defense in California, a business must demonstrate the following:
Continuous prior use: The defendant must show they have been using the mark before the plaintiff’s registration date or claimed usage date.
Geographic limitations: The defense may apply within the geographic area where the business has operated and gained public recognition.
Good faith use: Evidence that the mark was used legitimately and not with the intent to mislead consumers.
How Can Businesses Successfully Use a Prior Use Defense?
Building a strong prior use defense requires substantial evidence and strategic planning. Here's what businesses can do to effectively use this argument in trademark litigation:
Gather strong evidence: Documentation is critical when claiming prior use. Businesses should gather records such as sales receipts and invoices showing usage of the disputed mark, advertising materials displaying the mark, and digital records like website pages, social media posts, and email campaigns.
Prove geographic reach: California businesses must show that their trademark use extends to an identifiable customer base in specific geographic areas. Testimonies from local customers or references to distribution networks can strengthen this claim.
Demonstrate continuous usage: It’s not enough to show the mark was used previously; a defendant must also prove its continuous use leading up to the registration date of the plaintiff’s mark.
Work with legal counsel: Trademark lawsuits can be complicated, so it’s important to have an experienced lawyer on your side. A lawyer familiar with California trademark law can review your case, collect the proper evidence, and create a strong defense strategy.
Challenges Involved in Prior Use Defense
While prior use defense is an instrumental tool, businesses might encounter hurdles when relying on it. Some of these challenge might include:
Documentation gaps: Without precise evidence of usage, proving your case becomes significantly harder.
Geographic restrictions: Courts may limit the application of prior use defense to the areas where the defendant’s business is most active.
Competing claims: If the plaintiff has a federally registered mark, the burden of proving prior use lies solely on the defendant.
