Your partner in US law:

Tailor-made legal solutions for European companies in the USA

Our Services

Intellectual Property


We advise on the validity and enforceability of patents as well as on licensing agreements. We conduct IP due diligence audits.

Representation before the US authorities

We focus on subsequent applications for industrial property rights in the USA that were originally prepared for filing with a European office. Depending on the applicants' needs, we work directly with the applicants or with the applicants' European law firm.

SME consulting


Delegations and Chambers of Commerce of European countries are often the first point of contact for medium-sized companies regarding the US market. We provide support with specific legal questions. As part of our one-stop-shop service, we are available to medium-sized companies as a contact for all questions relating to US business law.



Technische Schwerpunkt

High Tech

We are one of the few law firms with technical expertise in the semiconductor sector as well as in the future technologies of quantum computing and artificial intelligence. In addition to patent prosecution, we have already supported several investors investing in these areas with IP due diligence audits.

Mechanics and electrical engineering

In addition to the high tech sector, we are also active in traditional mechanical engineering as well as in electrical and information technology. Our lawyers not only have theoretical experience, but also worked in research and development prior to their legal training.

Optics and medical technology

For years, we have been supporting Europe's most innovative companies and research institutions in obtaining and enforcing intellectual property rights, preparing IP reports and conducting IP due diligence audits for company acquisitions in the optics and medical technology sectors.
