Emilie B.

Cap Nova

We called upon for a trademark dispute. Our expectations were understood, and our interests were defended with great professionalism and irreproachable reactivity. If we had to do it all over again, we would have been accompanied in our thinking from the beginning! Today, our brand is our greatest pride and our best communication tool. Thank you!

Joffrey B.

Les Veilleurs du Net

My associate and I are very satisfied with the quality of advice and professionalism of Yamark. It is extremely comfortable and secure to benefit from an application made by a professional firm.

Calling on Claire is offering yourself serenity! Claire is highly professional and has the ability (rare in her field) to translate complicated things in a very simple way!

To be accompanied by her is to be sure to make the right choice and in complete confidence. We often think when we set up an activity that we can tackle this field alone just with the help of the INPI. We think that a professional costs too much... In my case, I regret not having met Claire earlier, I would have saved money and time by offering me her services...I could see it later!

Lanto A.


We wanted to register our trademark since a long time, present on the market for several years. But we had so many doubts and questions. Things that Claire knew how to sweep away from the first contact, in a very pedagogical way and with patience. Although we had never met, we were confident and reassured by so much professionalism and reactivity. Bravo ! We recommend her 100%!

Irene J.

Anthony G.


Clear advice and a very good follow-up.

François N.


A clear offer, a fast and efficient service with a real listening and relevant advice. Claire Yam enabled me to avoid some of the pitfalls of trademark registration and to go further than I had envisaged. I unreservedly recommend

Charlette G.

Us & Paname

Fast, efficient and pleasant, perfect service, I recommend!

Benjamin B.


After a few wobbly trademark registrations made by ourselves, we decided to call in a professional. Having a custom-made label reflecting our activity while being eligible to the INPI criteria allowed us to envisage the future of our activity with serenity.

Jeremy T.

Trouve Ton Transport

After an unsuccessful attempt to register my trademark with the INPI and the loss of more than 200 euros, I turned to to benefit from personalized support and advice, which allowed me to completely discharge myself of this mission and register my trademark under the best conditions. I am very satisfied.

Charline K.


Yamark intervened to secure the name of our HR consulting firm. In addition to the action with the INPI, we particularly appreciated the consulting dimension of our contact person. Very professional, she was able to put us in a relationship of trust very quickly thanks to her knowledge of the trademark law. Today, we recommend her with pleasure.


Baudouin N.

Via Terroirs

A trustworthy collaboration with Yamark. The firm filed our new trademark quickly, with relevant advice on wording, classes to be registered and similar trademarks. A long-term relationship that starts with the protection of our intellectual property.

Cedric C.


Great, thanks !

Sandrine G.


A special thanks to Claire who managed to answer our request very quickly without knowing us beforehand, advising us sometimes very late at night and popularizing the material. We highly recommend!

Christine V.

Prospectiv'h Consulting

Thank you for your availability and the quality of your interventions.

Laure B.

A Spark

Claire Yam knew how to advise me very well, took the time to explain the different possibilities, made me a most complete study and wrote me a wording that perfectly took into account my activities by adapting the terminology to what is done at the INPI (which I would not have been able to do myself as I did not have this knowledge). I had already filed a trademark registration alone for an association, but for my company I wanted it to be well done. I realize that I would have missed a lot if I had done it by myself. In addition, I had a very good contact with Claire, who takes the time for her clients. And it's so nice to see happy people who love their job and do it well!

Sandrine R.

Chlorofeel Coworking

I particularly recommend the services of Valuable advice that allowed us to avoid certain risks, a professional registration of our trademark that ensures us an optimal protection, a delegation of the administrative procedures for the present and the years to come. All this with a great reactivity and a very affordable price for a company in creation like ours!
