About us

KÄOSAAR is a leading intellectual property (IP) law firm in Estonia. Founded in 1992, we were one of the first Estonian IP law firms to emerge, and now have offices in Tallinn and Tartu.

We advise local and international clients on all IP matters in Estonia, the EU and internationally. We have more than 30 years of experience and in-depth knowledge in trademarks, inventions (patents, utility models), designs, geographical indications, domain names, copyright, business names, commercial secrets and know-how. This enables us to provide clients with quick and efficient solutions to any IP related issue. The agency employs 12 people, 6 of whom are patent/trademark attorneys and lawyers, who are valued experts in their field. Our staff includes people with considerable experience from the Estonian Patent Office and Estonia’s top-tier law firms. We have also participated in drafting laws and regulations regulating the field of intellectual property (e.g. the Trade Marks Act, Domain Disputes Committee Rules).

We are a member of various international intellectual property organizations: INTA, AIPPI, ECTA, FICPI and epi.
