About Marion Williams Law

Marion Williams Law is a small practice focused on international business law and intellectual property. Its work centers on registering and licensing patents, trademarks, and copyrights, and on forming and registering international business corporations in major financial centers. The firm's principal, Marion Williams, holds an LLB (Honours) from the University of London and has been licensed to practice as a CARICOM lawyer since 1992. Williams belongs to the Licensing Executive Society in the United States and Canada as well as its international body, and has contributed writing to the International Financial Centres Yearbook and to Euromoney.

The firm operates through a network of onshore and offshore legal and financial professionals rather than a single large office. A partner, Amoresio Antonio de Oliveira, brings more than twenty years of experience in Brazilian mining law, having served as chief legal consultant to Mineratins and Metamat in Brazil while also holding a university professorship. Between them, the practice covers licensing and technology transfer agreements, franchising, joint ventures, mergers and acquisitions, IP litigation, and project finance for developments such as hotels, resorts, energy projects, and infrastructure.
