Having been a staff member of a large Law Office for two years I decided to cut my own path along with only a few German clients together with a business associate.

Adding foreign clients my Law Office grew fast and after a cooperation lasting several years the previous partners amicably separated.

Thereafter the number of clients of my Law Office continued to grow and many of them use to share a long lasting bond of trust with my Law Office, some of them for more than 15 years.

While doing so, my clients appreciate my approach and philosophy.


It is an important factor to keep an eye on the enforcement of the Intellectual Property Right at the stage of elaborating the application therefore and to create quality along with affordable costs.

This philosophy may not serve a short term profiteering of my Law Office but – on the one hand – contributes to the long term business success of my clients and – on the other hand – creates confidence between my Law Office and my clients.


Concentrating my activities on Intellectual Property Law and my long term experiences both contribute to the fact that the enforcements of Intellectual Property Rights and defending my clients against attacks based on Intellectual Property Rights share a growing part of my professional business activities.
