karo IP – Your patent attorneys for
IP strategy and litigation

We continue to develop and move, together with our team, to the city center of Düsseldorf on 1st July, 2024. In this way, we create the preconditions for working in a modern and networked manner for IP strategies, IP rights, dispute avoidance and dispute proceedings. Our new main office at Steinstrasse 16 is located in close proximity to our friends, colleagues and experts in the patent and trademark fields and thus in the IP center of the city and North Rhine Westphalia (NRW).

For you as our clients there will be no changes. Because it is self-evident that we continue to stick to those principles that you have valued for many years when working with us: reliability, plain text, and creativity.

We continue to remain an IP-Boutique for prosecution and litigation, which develops customized protective concepts for your intellectual property, accomplishes the necessary tasks for securing IP protection reliably and efficiently, and finds the best solution for special problems as well.

We are certain that we can offer our services in the future with even more transparency, open-mindedness and joy in our common work with patents, utility models, trademarks and designs.

From now on you and our co-workers will be able to get to us by public transportation more conveniently. Our contribution to modern office creations.

We, the team of karo IP, look forward to moving on together with you.
