Considering that there are almost 60 territories in Africa, with a population of approximately 800 million, it is no surprise that the region has become a focal point for commercial expansion. At the same time, each country has its own set of intellectual property laws, with their own respective origins.


KISCH IP has developed – over the last 140 years – extensive knowledge and experience of the various legal systems and structures throughout Africa.


Further, because we view Africa as a reservoir of immense potential for global businesses and investors, we are eager to assist foreign and local clients with IP-related matters throughout the continent, as well as with general commercial legal services.
