Tania M. Castillo

Partner

Ms. Castillo is Managing Partner of Castillo y Castillo and Head of the firm’s Intellectual Property Department. She advises businesses based in the Dominican Republic and large multinational organizations on the full spectrum of IP-related matters including patents, trademarks, copyright, brand and IP portfolio management and exploitation, registration on the national sanitation and health registers and franchise and licensing agreements.

Chambers ranked her in Band 3 for IP, in recognition of her broad experience in handling complex IP matters. Sources state “When we have a complex issue, it is good to know that someone of her seniority is involved.” Legal 500 highlights Ms. Castillo as a recommended lawyer in IP, receiving praise from clients for her “clear advice”.

She is well known for her robust approach to patent, trademark and contract infringements, contentious issues relating to sanitation and health registration and frequently represents clients on major international disputes.

Ms. Castillo has always played a very active role in developing the Firm’s services to clients. She formalized the Department in 1989 in response to increasing client demand for first-rate IP support in the Dominican Republic.

As part of the firm’s commitment to supporting clients on all aspects of managing their IP portfolios, in 1996 Ms. Castillo established the affiliate firm Asesores del Caribe to provide reliable prompt advice on patent and trade mark applications across the Caribbean.

In 2005, she established the Bávaro office of Castillo y Castillo and took on the role of managing Profesionales, a collection agency affiliated with Castillo y Castillo.

Since then, Ms. Castillo has created the Immigration and Contracts Departments. She has also established the Tax Department.

Internally, she has also played a vital role in restructuring the firm’s support services to ensure they run smoothly and interact seamlessly.
