Patents

La Gro has an internationally renowned patent and technology practice. The team of specialized attorneys at law has extensive expertise in advising, contracting and litigating in all areas of technology, including chemistry, life sciences (pharma & biotechnology), mechanical engineering and high-tech.

We frequently and successfully act in complex (cross-border) patent proceedings in which our strategic insight and legal precision make the difference. This may involve the enforcement of patents (literal infringement or equivalence) in interim or final relief proceedings, or the revocation of erroneously granted patents and SPCs.

Our team has been litigating before the Unified Patent Court (UPC) since this new body came into being in 2023. Click here for more information on our UPC practice.

The Dutch courts in The Hague (holding exclusive jurisdiction in patent matters) have long been instrumental in shaping European patent case law. Highly respected for their well-reasoned decisions, they are famous for granting cross-border (preliminary) injunctions. Our patent litigators, through years of experience, have made a significant contribution to this cross-border practice. At some point this practice has been restricted by decisions of the Court of Justice of the EU (‘CJEU’). Recently, however, it has seen a resurgence. On 25 February 2025, the CJEU handed down its groundbreaking decision in BSH Hausgeräte v. Electrolux, allowing the national courts of EU Member States to grant cross border injunctions for infringement of European patents and exercise long arm jurisdiction, despite a possible invalidity defence.

It goes without saying that if clients need strategic advice or hands on assistance in effecting or resisting cross-border patent enforcement, we are the logical choice, whether this concerns the Dutch Courts or the UPC.

In the high-tech and telecom sector, we mainly assist international clients (right owners and implementers) in disputes over SEPs, with a focus on 4G/5G technologies. We conduct nullity and infringement proceedings and assist in licence negotiations on FRAND terms, combining technical expertise with legal decisiveness. 

We are best known internationally for our vast experience in Life Sciences (click here for more information) and Food & Agri (click here for more information).

The quality and impact of our team in groundbreaking patent cases, including UPC cases, has been recognised by Legal Directories, such as IAM Patent 1000, Chambers, Legal 500 and IP Stars:
