Anton is efficient and effective. The process of getting my trademark was easy. He also warned me of scammers who may contact me. He advised me to ignore them and contact him if there are any questions about any email. This is my second time using Leonov, and if I need intellectual property advice again, he is my go-to attorney.
Very good..
Professional, responsive, and very helpful throughout the process. Thank you.
We're working with Leonov Trademark on our trademark registration. Throughout the process they've kept us informed at every stage, responded quickly to our questions. Based on everything so far, I'd recommend them to anyone considering trademark registration.
Thank you for everything. We were able to file our trademark application easily without any issues. We were pleased that Amazon helped us with our trademark approval.
Anton has always been extremely responsive and buttoned up. Everything he's done for me has required very little effort on my end, and he always follows up quickly. I plan to keep working with him on all of my trademark work.

I can't recommend Anton Leonov of Leonov Trademark Law highly enough. Anton is currently handling four trademark applications across three of my businesses beginning in November 2025—two already in process and two more being submitted for a new venture—and the experience has been outstanding from start to finish. What sets Anton apart is his combination of deep knowledge, straightforward advice, and genuine transparency. He communicates directly with me whenever information is needed to process my applications, and he proactively keeps me informed of the status of each filing as well as any deadlines I need to be aware of. There's never any guesswork. His cost transparency has been refreshing—I always know what to expect, with no surprises. Anton has also been excellent at walking me through each step of the trademark process, making something that could feel complicated easy to understand. Above all, I appreciate his honest, straightforward assessments. Anton gives it to you straight, offering advice you can actually trust rather than just telling you what you want to hear. If you're looking for a trademark attorney who is knowledgeable, communicative, and genuinely honest, Anton Leonov is the one to call.
We worked with Leonov Trademark Law from late 2023 until our trademark registration was officially approved, and the experience was flawless. Throughout the entire process, Anton was incredibly professional, clear, and reliable. One of the best aspects of working with this firm was the transparent pricing. Everything was based on fixed, closed fees with absolutely no hidden costs or surprises. Anton guided and advised us at every single step, seamlessly managing both our initial "Intent to Use" application and the subsequent "In Use" filings. Communication was incredibly efficient. He would email us exactly what was needed, and the moment we provided the information, he proceeded immediately. We will definitely continue working with him for our upcoming brands. If you are looking for a trustworthy, on-time, and highly competent trademark attorney to protect your business, I cannot recommend Leonov Trademark Law enough.
Just filed my second trademark with Anton. He is prompt, professional, and transparent. He makes the entire process simple and painless. Highly recommend.
The Leonov Law Firm is my go to for any Trademark needs. They are always very knowledgable and make sure I get exactly the protection I am needing.
