Why Choose Us

120+ Years of IP-Focused Legal Experience

In an intensively globalized economy, creation, protection and enforcement of innovation is based on key factors: applied expertise, profound analysis of client interests, state-of-the-art knowledge of the domestic, European and international legal framework, and support by customized IT tools. If you need an expert to advise and implement the appropriate IP strategy for your business, you are in the right law firm.

With more than 120 years of IP focused legal experience, VAYANOS KOSTOPOULOS is the oldest and one of the leading IP law firms in Greece. Our philosophy is dedication and commitment to client-tailored needs of businesses coming from all branches of industry and services. Our clients and foreign associates enjoy state-of-the-art legal advice services in a timely and precise manner. Our clientele encompasses enterprises from multi-nationals to local businesses, including individual inventors, creators, designers, authors and other IP holders.

As from 1993 VAYANOS KOSTOPOULOS is headed by Dr Nikolaos Lyberis, Managing Partner, Attorney, as well as Patent and Trademark Attorney. He belongs to the fourth generation of lawyers in the same family running the Firm. Soon after becoming the Managing Director, he introduced the name VAYANOS & KOSTOPOULOS, which later changed to VAYANOS KOSTOPOULOS, thus maintaining the surnames of the previous two Office Heads. This decision symbolizes continuity with dynamic development as well as respect of long lasting professional principles.

Modernizing the organizational model of our offices and their three (3) departments (trademarks, patents, litigation), VAYANOS KOSTOPOULOS was transformed to a Law Firm in 2010.

VAYANOS KOSTOPOULOS Law Firm was established in Athens in 1900, being the first firm to introduce IP Law and Practice to Greece. The founder, Dr Alkiviadis Zoiopoulos, practiced from 1896 to 1933. He was a pioneer IP attorney and a multi-lingual legal advisor of the then foreign investors in Greece, running for the first two decades of the 20th century the only law firm exclusively specializing in trademark and patent law. He was fervently engaged in registering and protecting the rights of world leaders of manufacture such as Merck, IG Farben, OTIS, SINGER, BAYER, DAIMLER and others, and contributed to the creation of the first Greek Trademark Laws of 1983 and 1927.

Peter C. Kostopoulos, the successor of Zoiopoulos, led the offices from 1933 to 1973, gaining worldwide fame as a top IP attorney with deep knowledge of Greek and international Trademark and Patent Law.

Pierre Mamopoulos was a distinguished trademark and patent attorney for more than four decades (1930–1974), advising leading French industries. In the late '60s his offices were merged into Kostopoulos' practice, undertaken in the meantime by successor George St. Vayanos.

Prof. Emeritus Dr Dr George St. Vayanos expanded the scope of IP activities, focusing on IP prosecution and litigation, and led the firm from 1973 to 1993 before his professorship at the Aristotle University of Thessaloniki and later the Kapodistrian University of Athens.

Since 1993 the Vayanos Kostopoulos law firm is directed by Managing Partner Dr Nikolaos Lyberis.
