Patricio Grané Labat has over 20 years of experience of international investor-State arbitration, commercial arbitration, international trade and public international law. He has represented over a dozen sovereign States, and many leading multinational corporations, in challenging and complex disputes across numerous geographies, sectors and subject matters. These include leading a number of high-profile and politically sensitive investment treaty cases.

Patricio has extensive experience representing both claimants and respondents in arbitral proceedings under all the major arbitral rules, institutions and treaties, including ICSID, UNCITRAL, ICC, LCIA, DIFC-LCIA, SCC, NAFTA, and CAFTA-DR, as well as in ad hoc arbitrations under bilateral investment treaties. He has acted as counsel in approximately 50 investment arbitrations. He also acts as arbitrator, having been appointed by several sovereign States to the roster of arbitrators and panelists for the settlement of international trade and commercial disputes under BIT and multilateral treaties.

Patricio's expertise and accomplishments have led his peers and clients to recognise him as one of the world's leading specialists in public international law and commercial arbitration. He is listed as a "Leading Lawyer" in public international law by Legal 500 UK. Included in that category are a small number of practitioners who are identified as the elite of the profession, based on praise by their clients for their continued excellence. Patricio is also recognized in the 2019 Guide to the World's Leading Experts in Commercial Arbitration, which is the international legal market's leading guide to the top practitioners in the field of commercial arbitration.

As a recipient of a number of recognitions from legal directories, peers, and clients over the years, Patricio is described as an “exceptional” and “impressive lawyer”, possessing a “tenacious, analytical mind”, who “handles high-stake disputes with ease and aplomb” and is known for his “excellent command of investment arbitration issues and proceedings”. He has been praised for his “sharp legal mind”, “mastery of the jurisprudence and the precision of his thinking and advocacy”, “case management”, “coherent and effective strategies” and is recognised as being an “exceptional advocate”, a “skilled and experienced lawyer who knows exactly what to expect and anticipates the required course of action”, as well as “very good in hearings and able to focus on the big picture”.

Patricio is also widely acknowledged as one of the leading authorities in relation to Latin-American disputes. He has acted for the majority of States in the region and his background as a government official for a Latin American State means his exceptional insights in that area are highly sought after.

Patricio's Public International Law practice is broad. He has represented sovereign States in matters of state responsibility, treaty law, use of force, and international humanitarian law, as well as in judicial proceedings before European courts concerning jurisdictional immunities and diplomatic protection issues. He has participated in proceedings before the European Court of Human Rights and counselled individuals before the Inter-American Commission on Human Rights. He also represents sovereign States and corporations in trade disputes under the WTO Agreements, and appears before WTO panels and the Appellate Body. He has also been a consultant to the United Nations on trade issues.

Patricio is a frequent speaker at key international conferences, seminars and workshops. He is affiliated with leading research institutions and is a partner fellow at the University of Cambridge Lauterpacht Centre for International Law. He was also an Adjunct Professor at the Georgetown University, Edmund A. Walsh School of Foreign Service and an Adjunct Professor of Law at Georgetown University Law Center. Patricio holds an LLM from Georgetown University Law Center, obtained with distinction.

Patricio has multiple nationalities, reflecting his vast experience and varied cultural background. He speaks and conducts arbitrations fully in English and Spanish.
