The laws and regulations of digitalisation are developing rapidly. We can help you acquire and supply technology and IT, use and process data, and navigate the regulatory landscape with ease.
We work in a pragmatic and solution-oriented manner without compromising quality. Our experienced team stays ahead of the development and anticipates how contracts, business models, and operations are reshaped, including shaping the market with novel ways of contracting and novel solutions to complex issues.
When providing legal advice, we think of your business interests first. With our broad expertise, we proactively work with your strategic goals in mind, making sure that your legal and business interests are aligned. We always tailor the team to the needs of your matter and bring in experts from other practice groups at the firm where needed.
Our extensive experience in technology and IT and data law means that we speak your language and truly understand your business models and relevant market practices. We are one of the leading technology and data practices in Finland, with decades of combined experience from both sides of the table and across the world, and we advise clients both in the private and the public sector.
We strongly believe that artificial intelligence and data are business enablers, and we are happy to assist you in harnessing the potential while managing the risks associated with new technologies and use of data. While these matters are often complex, we can also support you in solving everyday practical issues.
We understand the complexity of technology-related disputes, whether before general courts or in arbitration. To achieve your business goals, we suggest litigation and settlement strategies that may consist of obtaining a fast interim injunction or other relief, settlement negotiations to resolve the case out of court and before trial, or creative but thorough tactics for litigation or arbitration.
We represent clients before Finnish authorities and courts, the European Union Intellectual Property Office, and the Court of Justice of the European Union. In arbitration, we represent clients in international arbitration institutes, such as the WIPO Arbitration and Mediation Center, in addition to Finnish and Swedish arbitration institutes.
Outsourcing has transformed from a mere cost-saving measure to a strategic catalyst for accessing market-leading know-how and cutting-edge innovations. Effective outsourcing strategies combine the benefits of the improved quality of IT and business processes with driven down costs and a more responsive business environment.
We act for both corporate and public-sector clients and top service providers and understand the priorities of clients across a broad spectrum of technologies and business sectors.
We can advise you in the public procurement of technology and digital assets. With the exceptional combination of a deep understanding in public procurement and technology within our team, we are able to offer strategic advice in the most demanding public procurement matters.
