Regardless of whether you are an innovation leader, a start-up or a provider of alternative solutions:
So that you remain or become a leader in your field, we support you in
protecting your investments in innovations,
building strong brands and
defending your company's freedom to operate.


...look for ways, those, who don't, look for reasons. Disruptive innovations, breaking with the traditional - successful companies must and want to constantly face new challenges. And we want to support you in this - with taylor-made IP strategies, solution-oriented advice and additional services such as IP audits and work-around checks.


With about 70 patent attorneys and IP professionals across Europe from various technical fields and 150 highly qualified specialists from 23 countries, we help you in obtaining, enforcing and licensing your own intellectual property rights and in defending your company against unjustified claims - in Germany, Europe and worldwide.



We are a medium-sized intellectual property law firm and part of a pan-European network. In Germany, we offer advice on all aspects of intellectual property (like patents, utility models, trademarks, designs, software protection, German employed inventors act) in our offices in the economic and innovation conurbations of Duisburg/Ruhr and Munich. For more details, just click on the following pictures.
