As a client, I feel totally at ease with Bolette because I know she has it all under control.” Senior partner Heidi Rehné is another essential contact for the address book, a smooth negotiator and poised litigator who leverages over 25 years in the game to progress matters forward in a commercially beneficial direction.

Knud Wallberg's Profile

Knud Wallberg has more than 25 years of experience in intellectual property as an attorney at law in private practice and as the former head of the Trademark and Design Department of the Danish Patent and Trademark Office.

Mr Wallberg draws on his comprehensive professional legislative, executive and judicial experience to guide his clients on the best practice use of trademarks, designs and domain names. He is able to explore their nuances and applications, and advise on the most practical means of incorporating them into the development and implementation of both a domestic and international branding IP strategy.

Mr Wallberg is an expert in assessing and developing the value contained within different IP rights and is able to quickly identify their potential market applications. As a specialist in online protection and the prevention of IP exploitation, he is also able to advise on how such rights fit into a wider strategy, offering detailed counsel on his client’s specific requirements, including where and how protective measures might be necessary.

Mr Wallberg has been a UDRP panellist with WIPO since 2000 and an expert member of the ‘.dk’ Complaints Board for Domain Names since 2003. He has also been an expert member of the Danish Appeal Board for Patents and Trademarks since 2013.

Mr Wallberg also helps guide both students and professionals through his lectures on IP law and domain names at both the law faculty of Copenhagen University and the Danish Institute for Intellectual Property Law Education.

He is the author of numerous publications about trademarks, domain names and IP-related issues. One of his most recent publications, now in its sixth edition, offers detailed insight into both the Trademark Act and subsequent amendments. It has been described as “the definitive guide to Danish Trademark law and practice” and is considered the authoritative text by many trademark professionals in Denmark.

Mr Wallberg is frequently recognised in the World Trademark Review’s WTR 1000.

As a client, you will find a skilled and knowledgeable practitioner able to help you secure, protect and enforce your ideas, whether you work in chemistry, green tech, mechanics, materials or biotech or emerging areas of digitalisation, software, AI and machine learning, among many others.

Our trademark and design practice assists all industries with filing and prosecution, availability and infringement opinions and has a special focus on EU trademark practice, including oppositions, cancellations and appeals before the EUIPO.

Litigation and disputes

When in need of experts in IP litigation and dispute matters, clients can rely on Zacco to represent them across our seven jurisdictions and beyond. Unlike more traditional law firms, we are renowned experts in intellectual property, meaning that we have both the legal and the technical expertise in-house to successfully represent your interests and enforce your intellectual property rights. Our experts can represent you directly, or provide litigation support to another legal counsel acting as your trusted representative before the authorities.

The legal practice serves all industries with legal advice and assistance related to intellectual property.

Zacco’s lawyers have successfully represented international clients in proceedings before national courts and the European Court of Justice.

Digital brands

With a significant portion of IP infringement now taking place online, we have introduced services to help clients stay ahead of new and emerging threats to both physical and digital IP. Our digital brands team can actively monitor your IP and brand rights online, assisting with registration and securing of traditional and emerging domains, and in identifying potential counterfeits or infringements across online marketplaces, social media and the metaverse.
