What Elzaburu does
Elzaburu (legal entity ELZABURU, S.L.P.) is a Madrid-headquartered, privately held specialist law firm focused exclusively on industrial and intellectual property. Founded in 1865, the firm operates as a Sociedad Limitada Profesional under the stewardship of the founding Diez de Rivera Elzaburu family, with Alfonso Diez de Rivera Elzaburu serving as President and Mabel Klimt as Managing Partner (Socia Directora). The firm delivers integrated advisory across trademarks, patents, industrial designs, trade secrets, copyright, plant varieties, domain names, intangible-asset valuation, due diligence, litigation/arbitration/mediation, anti-piracy enforcement, and related contracts to a horizontally diversified client base that spans large corporations, SMEs, startups, universities and research centers, technology centers, investment funds, and individual creators.
The firm's core service architecture combines traditional agency, law-firm, and consultancy functions with a proprietary digital platform, ELZACLOUD, launched in January 2023. ELZACLOUD provides clients with a secure portal for case management, document handling, power of attorney management, quality surveys, and self-diagnostic IP maturity assessments via the IP & IT Sensor. The firm's competitive positioning rests on extensive third-party recognition, including Band 1 ranking by Chambers & Partners Europe for Patent & Trade Mark Agents (the only Spanish firm so recognized), consecutive placement in Financial Times Europe's Leading Patent Firms (2026), Best Lawyers in Spain (2025) with 35 recognized professionals and 43 mentions, and recognition across IAM & WTR Global IP Awards, Managing IP Stars, The Legal 500, and Leaders League. Operational standards are formalized through ISO 9001:2015 quality management and ISO 27001:2022 information security certifications.
Elzaburu generates revenue through professional service fees on a quote-based engagement model, with no public pricing disclosure. Distribution is direct enterprise advisory, supplemented by referrals from other law firms and patent professionals. The firm complements its Madrid headquarters with China (Beijing) and Ibero-America coverage desks and maintains a thought-leadership channel mix (Blog ELZABURU, Annual Jurisprudence Yearbook, LinkedIn, X, YouTube, recurring European Patent Law Course). Total headcount sits in the 101-250 range; the partner-led practice areas include Media & Entertainment, Validations (European patent validation), Intangible Valuation and Due Diligence, Anti-piracy, Trade Secrets, Copyright, and general IP prosecution.

Elzaburu competitors and assessment
Company assessmentBroad incumbents
- Baker McKenzie: One of the world's largest law firms with a global IP practice and strong presence across Europe, Latin America, and Asia. Comparable to Elzaburu for cross-border IP portfolio management, particularly for clients with multi-jurisdictional needs.
- CMS (Spain): Top-tier European law firm with a significant Spanish IP, technology, and media practice. Comparable to Elzaburu as a competitor for Spanish and EU IP mandates, with greater pan-European reach.
- Clifford Chance: Global elite law firm with a strong IP and TMT practice serving large corporates and financial sponsors. Comparable to Elzaburu for high-end IP mandates involving multinational clients, but with a much broader full-service offering.
- Hogan Lovells: Global law firm with a top-tier IP practice spanning patents, trademarks, and copyright across Europe, the US, and Asia. Comparable as a deep IP competitor to large Spanish corporates and multinationals, but operating at significantly greater scale and global reach.
- Uría Menéndez: One of Spain's leading law firms with a strong IP, TMT, and corporate practice serving multinational clients. Comparable as a top Iberian law firm with overlapping IP advisory work for large corporates and international clients.
- Garrigues: Largest law firm in Spain and a major Iberian player with a substantial IP practice serving large corporates. Comparable to Elzaburu as a top-tier Spanish law firm with overlapping IP and corporate clients, though Garrigues is far broader and not IP-specialized.

- Herrero & Asociados: Spanish IP law firm specializing in trademarks, patents, and designs. Direct peer to Elzaburu in the Spanish IP market, competing for similar SME and corporate clients in the Madrid market.
- Grau & Angulo: Spanish boutique IP law firm offering trademark, patent, and design prosecution and litigation services. Comparable to Elzaburu as a domestic IP specialist, typically competing for similar Spanish and European IP mandates.
