karo IP | Japan Business

karo IP Patentanwälte supports German and European companies active in Japan as well as Japanese clients operating in Germany and Europe. With our Japanese clients we communicate in English and Japanese.

The karo IP team has many years’ experience in advising in cross-border projects between Germany and Japan. Our patent and trademark attorneys have built long-term trust-based relations with Japanese IP law firms and companies for many years. There is a regular and close professional exchange.

With the growing interest of Japanese clients in investing in Germany and Europe and the involvement of German companies in Japan, our firm is able to increase the legal support for all IP relevant matters significantly.

In our karo IP Blog we regularly inform you (available in Japanese) about current topics in IP law (patents, trademarks, designs) and about IP strategies, e.g. relating to digital technologies, such as IoT and industry 4.0.
