Patricio Grané Labat is a seasoned international law expert with 20 years of experience in international arbitration, international trade, and general public international law. He has represented claimant and respondent parties in investment arbitrations, including under NAFTA, CAFTA-DR, and various bilateral investment treaties. He has acted as counsel in institutional and ad hoc arbitrations under ICSID, UNCITRAL, SCC, LCIA, and ICC rules, as well as an arbitrator in international commercial arbitration. Mr. Grané, who served as a trade diplomat and negotiator for a Latin American country in Geneva, Switzerland, before entering private practice in 2001, also represents developed and developing countries in WTO dispute settlement proceedings and argues cases before WTO panels and the Appellate Body.

Mr. Grané has advised and represented sovereign States in a host of areas of public international law, including state responsibility, treaty law, use of force, and international humanitarian law. He has also represented sovereign States in judicial proceedings before European courts concerning jurisdictional immunities and diplomatic protection issues. He also counsels clients on multilateral trade issues and has served as a consultant to the United Nations on international trade law.

Mr. Grané, who is fluent in Spanish and a former government official, has unique insight and experience working with government officials, in particular from Latin American States.

He is a frequent speaker in international conferences in the areas of international arbitration and international trade, and has provided dozens of training and capacity building courses to government officials around the world. He was an Adjunct Professor of Law at Georgetown University Law Center before moving to London, UK.

Mr. Grané was inducted as a "Leading Lawyer" in the field of Public International Law by The Legal 500 UK (2019). Inducted in the same category are a minority of individuals identified by the market to be at the pinnacle of the profession and have received constant praise by their clients for continued excellence. It follows that most of the few individuals admitted to this category hold seats as chairs at key international law firms and have significant influence in international dispute resolution through their professional and academic activities. Mr. Grané is described as "an exceptional lawyer" and is praised for his "case management" and "coherent and effective strategies". He is known for his "excellent command of investment arbitration issues and proceedings" and is recognized as a "skilled and experienced lawyer who knows exactly what to expect and anticipates the required course of action".
