WomenOwned IP Boutique

Agile and Expert Advice

Women-Owned Intellectual Property Firm in Colombia

Founded in 1960, CASTELLANOS has been a women-owned firm since 1992. We are among the few firms in Colombia owned and managed by women only.

CASTELLANOS serves the international community, USA law firms, other foreign law firms, and in-house counsels worldwide in their IP needs. CASTELLANOS is not a full-service law firm – we focus on our intellectual property law niche and do it right.

We are a multidisciplinary team

Our team comprises professionals from several disciplines, such as law, mechanical engineering, chemical engineering, microbiology, economics, business management, accounting, and industrial engineering.

We are a responsive, helpful, and effective team

Our organization’s personality manifests itself through these values.

We make crossing borders smooth for you

Our goal is to be the face of Colombian intellectual property services abroad, so our clients can enjoy having an excellent international service level.



Castellanos is proud to be one of Colombia’s only female-owned law firms and this year sees María Guevara, a chemical engineer and expert patent filer, join the IAM Patent 1000.
