The TAoMA team is always pleasant, available and competent. It is clear in its explanations, structured in its working methods and efficient in responding quickly to any request. For me, its working methods distinguish the TAoMA team from that of other firms, because they allow us to know at all times where we are in each case in a clear and transparent manner.

In general, the people I work with in the firm are all welcoming, very efficient and available. More particularly, I work with Malaurie Pantalacci, who is always extremely clear in his explanations and reliable in his recommendations, thanks to his experience and his analytical mind.

Jean-Charles Nicollet is an exceptional lawyer. Great advice. A thoroughly upright straightforward person.

The team is receptive and listens to the client carefully. Their guidance take our strategic orientations and our financial criteria into consideration. They are pragmatic and realistic. The team is competent, conscientious but very pleasant and readily available. Team members are aware of the last information about intellectual property regulation and the latest changes to take into consideration or to be ready for. For example, they follow very closely the progress of Brexit consequences on intellectual property law.
