Firm overview

As part of CLAIMS network we work on projects all over the world. Located in Belgrade, we are highly visible on cross-border projects in the EU, UK, USA, South Korea, China, MENA region and many more jurisdictions. We are highly skilled and well-versed in the international law, and we understand the core ground of the IP law. This is why CLAIMS team is equally efficient in (almost) every jurisdiction, and this is our strong competitive advantage.

We are often involved in cases which don’t have a simple answer. Our work often sets precedents or overturns the outdated practice. This fact speaks clearly about the wealth of experience and skills our team brings to the tables of our clients.

We are active members of the international IP community. Our lawyers are members of INTA and AIPPI. Head of CLAIMS Balkans Ekaterina Pronicheva acts as a member of the Famous and Well-Known Marks Committee (INTA); Partner Alexey Petrov acts as a member of the Unfair Competition Committee (INTA); Partner Anastasiia Savosina is a member of the Designs Committee (INTA) and The Art Law Foundation (Switzerland). We are well-integrated in the international IP society, and we exchange ideas and insights with peers from all over the word. This is how we stay creative and efficient.

We educate and form the IP practitioners community in every country we settle in. We strongly adhere to the concept of sharing knowledge and passion to achieve synergies. CLAIMS maintain a youtube, linkedin and telegram blogs devoted to IP law peculiarities with over 5,000 subscribers in total. We also are involved into pro bono educational initiatives such as lecturing at universities and postgraduate programs as well as new intellectual property regulation activities such as IP Surrealism Manifesto or WIPO Conversation on Intellectual Property and Artificial Intelligence (AI).
