Chambers & Partners, the WTR 1000, Legal 500 and the clients they quote have described Thierry as "the pope of trade mark law in Belgium", or “a mastermind in European trade mark law”, who “wins praise for his brilliant mind and incredible intellect”.

Thierry is still to this day the only Belgian lawyer to have won a Lifetime Achievement Award at the World Leaders European IP Awards.
