Nicholas specialises in intellectual property and information technology law dispute resolution.

Nicholas has throughout his career accumulated broad dispute negotiation and litigation experience. He has been involved in several high-profile intellectual property disputes and has successfully argued before the Supreme Court of Norway.

His advanced grasp of the intersection between IP, TMT and corporate law enables him to meet his client’s expectations and needs in an ever more competitive legal landscape. In addition to receiving his professional legal degree from the University of Oslo, he holds the degrees of Master of Laws (LL.M.) and Doctor of Juridical Science (S.J.D.) from the United States, where he wrote about international enforcement of intellectual property rights.

Nicholas was named Rising Star in the 2022 and 2023 Legal 500 rankings, with clients praising him for being «efficient» and providing «pragmatic advice». He is highlighted as a promising talent in Kapital’s annual lawyer survey, and is also listed in the World Trademark Review guide for enforcement and litigation (WTR 1000).

I work with Nicholas Foss Barbantonis in trade mark matters. Nick knows our company well and is very clear and precise in his communication with me. He responds fast and counsels in a way that is easy to understand.
