Field of activity:

Marks & Clerk (Luxembourg) LLP is a legal firm of European patent and trade mark attorneys focused upon the capture, valorisation and management of intellectual property rights, including all of patents, trade marks, designs, copyrights and trade secrets, on a global basis.

Elevator Pitch:

Founded in 1887 in the United Kingdom, Marks & Clerk is one of the largest IP firms in Europe, and is Europe’s top filer of international patent applications (PCTs) in 2018 according to Managing Intellectual Property.

Since 1990, Marks & Clerk (Luxembourg) LLP has been the Luxembourgish presence of the Marks & Clerk group of intellectual property service providers, spanning 17 offices across Europe, Canada, China, Singapore and beyond, and employing over 300 patent attorneys, trade mark attorneys, lawyers and consultants, plus over 550 other staff.

Our patent and trade mark attorneys are regularly ranked in the top tier of Managing Intellectual Property’s IPStars for the UK, Scotland, Singapore, Hong Kong and Malaysia. Both our lawyers and our patent and trade mark attorneys are also featured in the Chambers, Legal 500, IAM Patent 1000 and WTR1000 guides.


Marks & Clerk (Luxembourg) LLP primarily offers intellectual property protection, strategy, dispute resolution, commercial and valuation services to local and foreign corporate clients.

From drafting, filing and prosecuting patents to grant, in technical fields as diverse and complex as computer-implemented inventions, oil and gas exploitation, digital communications and medical devices and formulations, whether in Luxembourg or the United States or China and beyond, to advice and registration of trade marks and handling of IP conflicts, with a long-term specialty in European patent validations for which our office is one of the largest specialists by volume in Europe, there is no service about intellectual property rights, which Marks & Clerk Luxembourg does not provide.

Business Model:

As a private legal practice, Marks & Clerk (Luxembourg) LLP has a straightforward and easily understood, legal fees-based business model. Our charging structure is clear, openly communicated to clients and competitive.

The commercial ethos of Marks & Clerk (Luxembourg) LLP is to be accessible, to make IP and related services understandable, to be prompt and above all cost-effective. Our quality of service is regularly praised by our clients.


Marks & Clerk (Luxembourg) LLP plans to continue increasing its volume of European patent validations activity, whilst substantially engaged in a drive to increase the provision of specialist patent, trademark and design-related services to the local corporate ecosystem with local and/or foreign IP servicing requirements.
