Trademark Attorney in California

Protect Your Brand Before Someone Else Uses It

Your name, logo, and brand identity are often the first things customers recognize—but without proper protection, they can be copied or challenged. Many businesses file trademarks without a clear strategy, only to face delays, denials, or conflicts later. Sorrentino, Sorrentino, Sabatini & Ryan helps clients across California protect their brands with a structured approach that starts with clearance and moves through registration and enforcement.

  • What happens if I get an Office Action?

    An Office Action is a request or objection from the USPTO that must be addressed to move the application forward.

  • How do I stop someone from using my brand?
