About the Attorney
Founder, Chanda Komatsu Law, LLC
When you work with me on your brand, you get straightforward answers, plain English, and a filing strategy tailored to your business. We'll move at your pace, answer every question, and make sure you leave understanding what you own — not buried in trademark jargon. My job is to make the hard parts feel manageable, and to help you protect the name you have worked to build.
I've been practicing law for 30 years, serving clients across the Midwest and, increasingly, well beyond it. I hold a Bachelor of Sciences in International Business from Illinois State University and a Juris Doctorate from the University of Illinois, Champaign-Urbana — an international business foundation that fits naturally with representing both U.S. and foreign clients before the USPTO.
Most business owners know they should register their name, but the classes, the specimens, and the what-ifs can feel like too much — so it gets pushed aside for "someday," often until someone else files first. I understand that hesitation, and I've seen the relief that comes from finally getting it done. A trademark is property, and like everything else you've built, it deserves a plan.
Who We Serve
A U.S. trademark is worth having no matter where you call home. We handle both sides of the register with the same calm, plain-English care.
Founders, small businesses, and growing brands across Minnesota and every U.S. state. From first use in commerce to incontestable registration, we clear, file, prosecute, and maintain your mark — and because we also plan estates, we can fold your brand into your succession and exit strategy from the start.
Based outside the United States? You don't need a U.S. address to own a U.S. trademark. We act as your appointed U.S. representative for service of process, file and prosecute before the USPTO, and — when it helps — extend a U.S. registration abroad through the Madrid Protocol.
What We Offer
Whether you sell down the street or across an ocean, protection should match your ambition — not exceed your budget.
Before you invest in a name, we check whether it's actually yours to use — U.S. federal, state, common law, and key foreign registers.
We represent U.S. and international clients alike before the USPTO — preparing and prosecuting applications, specimens, and Office Action responses in plain English.
Based abroad? You don't need a U.S. address to own a U.S. trademark. We handle U.S. filings, appointments of U.S. representative, and Madrid Protocol extensions into other markets.
Monitoring for confusingly similar marks, cease-and-desist correspondence, and opposition or cancellation strategy.
Docketing, Section 8 & 15 declarations, and renewals — so a deadline never quietly costs you your brand.
Trademarks are property. We assign, license, and place them into your trust so your brand passes the way you intend.
