Trademark Change of Ownership Services in California
When a trademark changes hands—through a sale, merger, business restructuring, or inheritance—the USPTO must be notified. Failing to record the change properly can jeopardize your rights. At SARI LAW FIRM, we help businesses and individuals across California navigate all forms of trademark ownership transfers and assignments, ensuring legal clarity, accuracy, and continuity.
When You Need to Update Ownership
You must file a trademark ownership change when: You sell or purchase a trademark; Your business merges with another entity; There is an internal restructuring (e.g., from LLC to Corporation); The trademark owner passes away (estate assignment); You acquire a trademark as part of an asset purchase or acquisition. These updates are not automatic. You must file a trademark assignment with the USPTO Assignment Recordation Branch to make it official.

FAQ
Can I just update the trademark owner in my USPTO account?
No. Ownership changes require formal recordation through the USPTO Assignment Recordation Branch. It’s a separate legal step.
Do I need a lawyer to assign a trademark?
While not required, attorney-prepared assignments help ensure the transfer is legally binding, enforceable, and includes goodwill (which is essential).
What’s the difference between an assignment and a name change?
An assignment transfers ownership to a new party. A name change is used when the same entity changes its legal name. Both require documentation and USPTO filing.
How long does USPTO recordation take?
If filed electronically and properly formatted, most recordations are processed within 3–5 business days.
Can you help with multiple trademarks in one transaction?
Absolutely. We handle large trademark portfolios and can batch assignments across multiple serial numbers for efficiency.
