Testimonials
Collated independently by Legal 500 research team.
- ‘The competition team is of the highest quality, demonstrating not only legal but also economic knowledge – both essential in this field. Both the team leaders and associates exhibit above-average expertise in this area, making them arguably the best competition team nationally.’
- ‘As a PLMJ client, I believe the firm stands out from others due to its experience in competition law, its highly practical approach to the issues, and its adaptability to the diverse stakeholders it interacts with within the company.'
- ‘PLMJ's competition team is excellent: attentive to detail and always available. They stand out for their ability to understand the industry and the client's business model, which is essential for an effective defence. Their responsiveness (always quick and well-founded) makes the PLMJ team a benchmark choice in competition law.’
- ‘PLMJ has consistently impressed with its professionalism and collaborative spirit. The team is responsive, commercially minded, and easy to work with across borders. Their ability to align with international counsel and deliver clear, pragmatic advice makes them a strong partner for complex matters in competition law. We worked with them on merger control and complex distribution issues.’
- ‘Martim Valente delivered a very practical training for senior management and acted as an inspector in a mock dawn raid, managing to portray his role so well that the internal teams didn't realise it. In turn, Rodrigo Policarpo is always available and is leading several compliance initiatives on his own.’
- ‘Martim Valente continues to be my go-to lawyer in Portugal, particularly for tech matters. Martim is an exceptional advocate across both Portuguese and EU law. Moreover, he is deeply embedded in the tech landscape with an excellent grasp of cutting-edge and emerging technologies, e.g., AI. He is extremely user-friendly and combines this with a strong relationship with the AdC, which has facilitated my clients in developing their own relationships with the regulator.’
