Our services

We are a small and tightly focused group of professionals and intend to remain so. On our core competency areas, we are among the best in class, while we also serve our clients on most other legal issues related to their daily business.

Services Technology & Commercial Contracts

In matters involving technology and all things digital, Inventio is best in class. We assist both buyers and suppliers of technology in various demanding ICT contract arrangements as well as in dispute resolution related to such. We act as a de facto outsourced legal function for a number of technology companies. In addition, data protection matters and technology transactions fall within our core competencies.


Services Employment Law & HR

Legal advice related to employment relationships and human resources and assisting clients in related dispute resolution are one of the cornerstones of our practice. We assist companies in diverse employment-related matters, including disputes, and also in criminal matters involving the workplace. The latter includes e.g. offences related to workplace safety and misappropriation of business secrets.


Services Dispute Resolution & Corporate Crime

Our lawyers have ample experience on handling demanding litigation assignments, both in public courts as well as in arbitration. We have particularly strong experience in contentious matters related to technology, intellectual property rights, and employment law. Among our key competencies is counseling clients in matters involving criminal offences in the corporate environment. We possess versatile experience in handling demanding criminal cases, and we regularly act as counsel in disputes involving e.g. work place safety, fraud, misappropriation of confidential information, bribery, securities market violations, debtors’ dishonesty, and information technology systems.


Meet our team

A law firm is precisely as good as the people working therein. Common to all our lawyers is a versatile background and the ability to look at issues also from beyond the vantage point of their respective specialty area. While dear to us, we understand that law typically has no intrinsic value but is merely a tool in pursuing the client’s interests.
