Kalkoff & Partner continues as a fully operational firm. Our equipment allows a safe and reliable remote access at any time. If Patent Offices or courts inform us about changes or if they reschedule e.g. oral hearings or terms for responding to official actions regarding your files, we will keep you informed.



At our Dortmund office, a team of patent attorneys has formed a long-lasting co-operation.

We offer our services in all areas of intellectual property: patents, trademarks and designs.
