Diez Canseco Abogados


Diez Canseco is a highly specialized law firm which has been consistently devoted to address the most complex matters required by our clients mainly in the Competition, Intellectual Property, Telecommunications, Media and Technology (TMT) and Data Privacy fields. Regardless of how challenging or one-in-a-kind the mandates entrusted to us are, we are committed to provide practical solutions in a language that is understandable not only by legal counsels but also by business teams.

Despite initially focusing on the four topics mentioned above, Diez Canseco has steadily grown over the past seven years, creating new departments and hiring capable partners and senior associates able to handle regulatory issues whether in public utilities sectors (such as electricity, water and sanitation, or oil and gas) or not; or matters concerning public law advice, life sciences, merger clearances, as well as compliance needs. It goes without saying that despite expanding the range of their activities, Diez Canseco remains committed to offering a “boutique approach,” in which each project is constantly overseen by a Partner who is then actively involved in the delivery.

Litigation is ingrained in our DNA. Our firm is actively involved in litigating some of the high-profile antitrust cases (including leniency and rewards programs), as well in merger control filings. Likewise, we cover unfair competition, advertising law, consumer protection, bureaucratic barriers, data privacy, bankruptcy law and dumping and subsidies cases in Peru and the Andean Community. Furthermore, in line with our interest to assist our clients not only in a reactive but also in a proactive way, we have made significant efforts to strengthen our involvement in compliance programs, the issuance of opinions concerning commercial initiatives, and daily advice on ordinary course of business issues.

Due to our high level of specialization in the broadest range of trademark, copyright, and even patent matters, national and international major players have sought us out in the area of intellectual property. The year 2022 will go down in history as the year Diez Canseco began actively exporting trademarks by acquiring new clients with global portfolios. Aside from prosecution work, we are particularly capable of handling disputes, litigation cases before authorities, private negotiations, contractual schemes like franchise and license agreements, or transactions involving intellectual property with the same level of expertise and speed. We are able to provide this service on a global scale and in numerous jurisdictions because to our extensive network of agents.

Unlike the vast majority of legal firms on the market, Diez Canseco has a team of professionals who take a unique approach, combining private expertise with extensive public background at the highest level of many government agencies. Almost all of our team has served as officers at the Peruvian competition and intellectual property agency (INDECOPI), and we have former members of the telecommunications regulatory agency (OSIPTEL), the energy and mining regulatory agency (OSINERGMIN), the United Nations Conference on Trade and Development (UNCTAD), the World Bank (WB), the World Intellectual Property Organization (WIPO), the Organization of American States (OAS), and the Andean Court of Justice. This powerful background, as well as the strong academic credentials of our team (professors and lecturers at Peruvian most prestigious universities) are key factors in encouraging deference for our views and arguments before the authorities.
