Testimonials

Collated independently by Legal 500 research team.

  • They are very good at intellectual property, thorough, and generous with their time.
  • They are technically excellent and very honest and fair with their fees.
  • The team's main differentiator lies in the human and professional qualities of its members, combining experience, sound judgment, and consistently high-quality execution over time. These are lawyers who stand out not only for their technical expertise but also for their ability to understand the business and build long-term, trusting relationships. In particular, I would highlight partner Fernando Jiménez de Aréchaga, whose leadership, strategic vision, and deep knowledge of M&A have been key in complex transactions. His direct involvement provides confidence in decision-making and raises the standard of work. Likewise, associates Carolina Bianchi and Daniela de Castro excel in their high level of commitment, rigor, and management skills. Both have demonstrated an excellent combination of attention to detail and efficiency in execution, providing essential support on a daily basis. Compared to other firms, the team distinguishes itself through its close relationship, continuity, and accumulated understanding of the client, resulting in more agile, aligned, and effective advice.
  • What distinguishes this practice is its ability to combine highly specialized M&A and Intellectual Property advice with a deep and sustained understanding of the client's business. After several years of working together, the team not only brings technical excellence but also accumulated knowledge that allows them to anticipate needs and offer solutions specifically tailored to our context. For in-house counsel, one of the key attributes is reliability: the team responds consistently, with high standards of quality and within demanding deadlines. This is complemented by clear and pragmatic communication, focused on facilitating decision-making rather than presenting theoretical analyses. Their versatility is also noteworthy, as they can handle both complex transactions and specialized intellectual property matters with the same level of rigor. Compared to other firms, they are very favorably positioned, especially in terms of service continuity and team stability, which is not always the case. This consistency generates significant efficiencies and a very fluid work dynamic. Regarding innovations, we value their evolution towards more collaborative and flexible working models, as well as greater integration between departments (particularly between M&A and IP), which adds value in transactions where both disciplines converge. Furthermore, their openness to work and coordination schemes tailored to client needs reflects a practical approach that sets them apart from other firms.
