Castellanos & Co

What Castellanos & Co does

Castellanos & Co is a women-owned intellectual property boutique law firm headquartered in Bogotá, Colombia, founded in 1960 and women-led since 1992 when Ximena Castellanos assumed the managing partner role at age 25. The firm operates exclusively in IP law — it is not a full-service law firm — and delivers six core service lines: trademark prosecution, patents and industrial designs, copyrights, regulatory work for sanitary authorizations, domain names (including WIPO ADR representation), and data protection compliance under Law 1581 of 2012. Its technical differentiator is a multidisciplinary team combining lawyers with mechanical, chemical, and industrial engineers, microbiologists, economists, and business managers, which enables it to handle patent prosecution across all technology fields, including life sciences (where it has been recognized for work on medical device patent protection).

The firm sells professional services on a quote-based, hourly/engagement billing model that is not publicly disclosed. Its go-to-market is direct engagement with international law firms (primarily USA and other foreign firms), in-house corporate counsel at multinational companies, and SMEs — all seeking Colombian IP protection. It is the only disclosed firm-wide client named in the source material: GC Aesthetics Ltd, a life sciences/medical device enterprise, illustrating the firm's vertical specialization in pharmaceutical and medical device patent prosecution. The firm holds no external funding, has no parent company, and has no disclosed ownership beyond its two principal partners (Ximena Castellanos, Managing Partner; Margarita Castellanos, Principal Partner).

Castellanos has been continuously recognized across the major IP analyst rankings — WTR 1000, IAM Patent 1000, Chambers Latin America, Legal 500 Latin America — and was named Managing IP Law Firm of the Year in Colombia for 2026. It maintains active memberships in the major international IP associations (INTA, ASIPI, AIPPI, FICPI, ACPI, ECTA, IPO) and operates a bilingual English/Spanish website with social media presence on Instagram and Facebook, plus an email newsletter. The firm has 16 employees and operates from a single Bogota office; it has no disclosed technology platform, software product, or AI capability.

Others

Broad incumbents

• Baker McKenzie (Colombia): Global law firm with a Bogotá office providing IP services alongside its broader international practice. Competes for multinational IP portfolios where clients prefer global coordination over boutique specialization.
• Posse Herrera Ruiz: One of Colombia's largest full-service law firms with a substantial IP practice. Competes with Castellanos for multinational IP mandates but offers broader legal services as part of a wider portfolio.
• Brigard Urrutia: Leading Colombian full-service law firm with established IP capabilities. Serves multinational clients seeking integrated legal solutions, often competing with specialty IP boutiques on larger matters.
