Firm overview

Zacco is an international full-service IP firm, with over 100 patent attorneys, 70 trademark and design professionals including 40 attorneys at law, 20 experts in corporate domain management and online brand protection, and 20 cybersecurity specialists . We operate globally and in most sectors, and our aim is to view the world as our customers do, building practical IP strategies that secure their ideas, innovations and brand character.

Together we help organisations to develop, manage and protect the value of their IP throughout its lifecycle. Combining physical and digital solutions, from the creation of new assets and identities, to monetisation and enforcement of rights, to ongoing monitoring against infringement and abuse. Zacco, and many of our colleagues, regularly achieve Top Tier or Gold rankings and recommendations from Managing Intellectual Property, World Trademark Review, Intellectual Asset Management and The Legal 500, which we believe independently verifies our commitment to quality, excellence and innovation.

Patent, Trademark and Design Prosecution

Our international presence means a single point of contact can handle prosecution in multiple jurisdictions. Many of our colleagues are European Patent Attorneys, with a growing number authorised to represent clients directly before the Unified Patent Court (UPC). At Zacco, you will find a skilled and knowledgeable IP practitioner able to advise and assist you with all current and emerging fields of technology, whether you work physically in chemistry, greentech, mechanics, materials or biotech, or digitally in digitalisation, software, AI or machine learning, among other areas.

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

We cover multiple European jurisdictions directly including the EUIPO/EPO, the United Kingdom, Germany, Norway, Sweden and Denmark, and we operate internationally through a comprehensive network of trusted long-term global partners. We also provide a range of IP portfolio management and IP support services.

Litigation and Disputes

When in need of expertise in IP litigation and dispute matters, clients can rely on Zacco. We are renowned experts in IP, with both the legal and the technical proficiency in-house to successfully represent your interests and enforce your IP rights. This could be directly, in cooperation with leading law firms, or providing litigation and technical support to other counsel or trusted representatives before the authorities.

The legal practice serves all industries with advice and assistance related to IP. This includes due diligence, drafting and negotiation of contracts or licensing agreements, or Data Protection, marketing law and other compliance matters. We also advise on e-commerce, litigation, domain name conflict resolution, customs surveillance and counterfeit prevention, among other areas. Zacco has successfully represented international clients in proceedings before national courts and the European Court of Justice.

Digital Brands, Corporate Domain Management and IT Security

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, identifying and removing

potential counterfeits or infringements across online marketplaces, social media and the metaverse. Our Corporate Domain Management experts can assist with the registration or acquisition of traditional and emerging domains, including .brand solutions, alongside more general renewals, portfolio consolidation and email or domain security. We also provide cybersecurity training and testing, digital forensics and secure software development services.

IP360: The Future of Intellectual Property

When the world changes, so do we. The introduction of IP360 recognised that IP rights do not exist within a bubble – they form part of a wider IP ecosystem that encompasses everything to do with protecting the value of an organisation. As we have grown, so too have our services, providing exceptional capability, unique geographical reach, and protection that stretches from the first flash of an idea through patents, trademarks, online brand protection and beyond, across the entire IP lifecycle.

More than 150 years of innovative thinking

We have a long history of protecting, monetising and enforcing IP, and list many leading brands and innovators as clients. Our focus on close collaboration, technical expertise and high quality makes Zacco one of Europe’s leading IP solutions specialists.
