Intellectual property: Tier 2
The Legal 500 highlights our practice's strength in pharmaceutical and life sciences work, where we help local and foreign clients secure and defend their IP rights. The team handles regulatory exclusivities, patents, trademark disputes and portfolio management (The Legal 500).
The guide recognizes the team that leads the practice:
José Meythaler Baquero, for litigation on behalf of leading pharmaceutical and agrochemical multinationals.
Sebastián Meythaler, a go-to adviser for local and multinational pharmaceutical companies across all IP matters.
Andrea Araujo, head of the IP litigation group.
Emily Moreno, deputy head of IP since April 2026, whose arrival strengthened the practice.
Notable work includes a successful opposition, on behalf of GrupoFarma del Ecuador, against a three-dimensional trademark application covering a standard tablet shape. The guide also lists Gustador and Tiendas Tambo among our key clients.
Tax: Tier 4
According to The Legal 500, our tax team advises on compliance and tax structuring, including tax recovery, VAT refunds, market entry and regulatory alignment. On the contentious side, it challenges tariffs and pursues tax refund claims (The Legal 500).
The practice is led by Gabriel Pinto Navarrete, who focuses on tax litigation and planning. In testimonials gathered by the guide, clients call him "an excellent tax lawyer" and value José Meythaler's leadership in coordinating all our services.
The guide also cites our work for a global shipping and logistics group in a customs penalty dispute over bonded-warehouse operations. We obtained the annulment of all fines, and the client kept its logistics and warehousing permits without interruption.
Dispute resolution: Tier 4
The guide points to our team's work in commercial arbitration and in civil, commercial and administrative proceedings, with a strong track record in insurance coverage, healthcare and public infrastructure disputes (The Legal 500).
The practice is co-led by José Meythaler Baquero, founding president and managing partner, who focuses on civil and commercial litigation, international arbitration and IP disputes; and Vanessa Aguirre Guzmán, who focuses on arbitration and constitutional litigation.
Among the highlighted matters is our representation of Empresa Pública Metropolitana Metro de Quito in an insurance coverage dispute over losses caused by ground subsidence on the Quito Metro project, a claim involving roughly USD 100 million. The guide also names Sudamericana Integral de Construcciones Sudinco and Consorcio Cosedi among our key clients.
