Calderón & De La Sierra

What Calderón & De La Sierra does

Calderón & De La Sierra is a Mexican law firm headquartered in the Santa Fe district of Mexico City, founded in 1982 as a trademark boutique and operating for over four decades as a private professional services partnership. The firm employs 51–100 people organized around ten partners and provides specialized legal services across intellectual property prosecution and enforcement, regulatory approvals, corporate and commercial law, litigation, entertainment, and a recently launched art law practice. Its core service offerings span trademarks, patents, copyrights, trade secrets and unfair competition, transmission of rights and licensing/franchising, regulatory matters (including COFEPRIS and SENASICA procedures), corporate transactions, and litigation before Mexican IP authorities and federal courts.

The firm generates revenue exclusively through professional services engagements — quote-based legal counsel, prosecution, and litigation — billed directly to clients under arrangements typical of law firm partnerships. Its go-to-market relies on professional reputation, international legal directory recognition (Chambers & Partners, IAM 1000, WTR 1000, The Legal 500, Managing IP), and active leadership in global IP associations (INTA, AIPPI, ASIPI, AMPPI, LESI, ICC, IPO). Client acquisition is driven by direct engagement via phone, email, and website contact forms, supplemented by an international referral network spanning 70+ countries. The firm segments its clientele across corporate and business clients (primary), pharmaceutical/regulated industries, entertainment and media, and litigation engagements. Technically, the firm is a non-software, non-platform legal practice with no disclosed proprietary technology, APIs, or AI/ML capabilities; its primary assets are partner credentials (e.g., Carlos Pérez de la Sierra as IP Star and IAM gold-rated practitioner; César Ramos having handled 18,000+ patent applications; Miguel Ángel Merino having managed 3,000+ software IP litigations) and accumulated institutional knowledge of Mexican IP regulatory frameworks, including the recent Federal Law for the Protection of Industrial Property (FLPIP).
