Maria Carolina Gallego I.
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.

It was the fact that my lawyer was patient, understanding, and explained things instead of just telling me something. Keep on doing what you are doing, thank you.
