Unified Patent Court Litigation – one fully integrated team

Unified Patent Court litigation requires early, well-calibrated strategic choices, often under tight procedural timelines, both at first instance and on appeal.
Altius De Clercq unites ALTIUS and De Clercq & Partners in one fully integrated team dedicated to handling infringement and revocation actions before the Unified Patent Court.
This allows you to rely on aligned legal, technical and strategic expertise from day one, supporting swift, pragmatic and client-driven UPC litigation.

What brought us here?

Built for Unified Patent Court litigation.

The Unified Patent Court (UPC) has changed how to deal with patent disputes in Europe. Specialized judges with both legal and technical expertise handle proceedings which are faster and more front-loaded.

Accordingly, that shift calls for a different way of working in patent litigation. Traditional handovers between legal and technical teams no longer fit the pace, structure or front-loaded nature of UPC litigation.

To meet that reality, we created Altius De Clercq as a fully integrated team, purpose-built for patent litigation before the UPC. You work with one team that brings legal and technical expertise together from the outset. We operate in a single structure mirroring how UPC proceedings operate, at both first instance and on appeal, and meeting the need for consistent strategy across different proceedings.

Who are we?

Scale that matters. Depth that delivers.

Altius De Clercq brings together ALTIUS and De Clercq & Partners, two leading patent firms based in Belgium with long-standing top-tier rankings in IAM Patent, IP Stars, Chambers, Legal 500 and other leading directories.

Together, we form one integrated UPC Litigation Team with nearly 30 qualified UPC Representatives. Our team combines litigation strength and deep technical expertise across all major technology sectors.

Our scale and depth allows us to assemble the right legal and technical mix for each case. This enables us and to act swiftly and consistently throughout UPC proceedings, from early strategic assessment onward. We handle provisional measures, evidence gathering proceedings, infringement actions and revocation actions, at both first instance and on appeal.

What do we bring?

Clear advice.
Decisive action.

Patent litigation strategy before the UPC requires clear choices early on. Proceedings are front-loaded, timelines are tight, and early decisions on procedure, arguments and evidence often determine the case’s outcome.

We support you with focused, coordinated patent enforcement advice from day one. Legal, technical and strategic considerations are assessed together, allowing to identified and address key issues early and efficiently.

For you, this means clarity and control. You work with one team, receive clear advice, and can take informed decisions quickly. That allows you to act with confidence when UPC timelines demand action, at first instance or on appeal, and when alignment is required between different UPC proceedings or with parallel proceedings before the European Patent Office (EPO) or national courts.
