Eduardo Guzmán represents telecommunications, media and technology (TMT) companies on regulatory and dispute resolution matters in the US and Latin America. He regularly advises carriers and providers on the implications of regulatory policy involving telecommunications and emerging technologies, and defends them in litigation and other proceedings involving those issues. He also counsels clients across diverse industries on compliance with state and federal laws regulating marketing and consumer communications.

Eduardo regularly helps telecommunications providers navigate and adapt to a changing regulatory landscape. He advises providers on matters such as traditional common carrier regulation, the regulation of video, VoIP and other IP-based services, the transition to IP-networks, interconnection, the regulation of broadband internet service, universal service and consumer privacy. He negotiates complex agreements related to the interconnection of networks and the offering of regulated and non-regulated services.

Eduardo also dedicates a significant part of his practice to representing TMT companies in administrative proceedings, litigation matters and arbitration proceedings. He has particular experience litigating intricate jurisdictional and regulatory policy issues and handling commercial disputes in domestic and international arbitration proceedings before the American Arbitration Association (AAA), the International Centre for Dispute Resolution (ICDR) and the International Centre for the Settlement of Investment Disputes (ICSID).

In addition, Eduardo has extensive experience helping companies across a range of industries develop internal programs and policies for compliance with federal and state laws regulating telemarketing and other communications with customers, including the Telephone Consumer Protection Act (TCPA), the Telemarketing Sales Rules (TSR), the CAN-SPAM Act and the Fair Debt Collection Practices Act (FDCPA). He also regularly conducts compliance audits, reviews internal policies and practices, and makes practical recommendations to clients aimed at reducing exposure and potential liability under these statutes and regulations.

Eduardo has particular experience in the Caribbean and Latin America. He regularly represents the interests of private corporations and industry groups in matters before administrative agencies and other government entities in Puerto Rico, and advises on legal, business, regulatory and political issues in connection with their plans to establish new operations in Puerto Rico and/or their existing operations in Puerto Rico. With the recent changes in US policy toward Cuba, Eduardo has counseled US companies considering entering the Cuban market, and he has published articles and is frequently invited to speak on the Cuban telecommunications sector, the history of foreign investment in that sector, and the risks and opportunities for US investors looking at Cuba.
