The interest is wonderful
The quick response time , vast knowledge and services given to me were wonderful .
Anton Leonov handled my trademark application and was extremely helpful throughout the process. He provided detailed information and guided me clearly at every step.
Thank you to the team for managing the entire process so well.
Anton handles trademark work for my clients as well as my own company lately. He is knowledgeable, detail-oriented, and very transparent about risks and strategy. It’s been a reliable and professional experience from start to finish. I’d recommend Anton for your TM work.
Excellent service! They provide tremendous support, with immediate answers to all questions and sharing of all anticipated risk analyses.
My trademark application was handled by this attorney, and unfortunately the process involved serious communication and follow-up failures. A critical USPTO deadline was missed, which resulted in the application being abandoned.What is most concerning is that despite my phone number being on file, I was never contacted by phone regarding such an important and time-sensitive matter. Communication was limited to email only, and there was no clear or proactive effort to ensure I understood that missing this deadline would permanently cancel the application.As a result, the application became inactive, and I am now being asked to pay again to reapply. In my opinion, this situation did not arise from my neglect, but from a lack of adequate follow-up, responsibility, and client communication.For a trademark matter—where deadlines have irreversible consequences—I expected a much higher level of professionalism and diligence. Unfortunately, that standard was not met.
As international clients, we had an excellent experience working with Anton Leonov during the trademark registration process; communication was clear and timely, every step was explained transparently, and the entire process was handled efficiently and professionally, which gave us great confidence despite being based outside the U.S. We are very satisfied with the service and would highly recommend Anton Leonov to anyone seeking reliable U.S. trademark registration support.
They have a successful system. Their support is very attentive, and their responses are extremely fast.
