Your law firm’s Norwegian IP-partner

Onsagers is the largest ‘top-tier’ rated, full-service Intellectual Property law firm in Norway

With more than 30 patent attorneys and attorneys at law, we are not just the largest IP law firm in Norway, we are also one of the country’s longest established and most knowledgeable.

This is the reason more clients turn to us for IP legal advice and expertise. It is also the reason Onsagers has been ranked as a top-tier legal advisor within IP every year since 2007.

Onsagers is a full-service firm, with capabilities that span the entire width of IP –from pre-filing analyses to court proceedings, and all matters in between. We offer a ‘one-stop-shop’, where patent attorneys and lawyers work in close collaboration.

Our unique approach ensures all relevant aspects are covered, and brings quality, cost and strategic benefits.

We employ more ex-Norwegian Patent and Trademark Office (NIPO) attorneys than any other firm, including seven in the last two years alone. In fact, almost all our attorneys can claim NIPO experience at some point in their careers. This means that when it comes to prosecution, we understand what is relevant as a Norwegian Partner.

Onsagers attorneys regularly act as expert witnesses and expert judges. The resulting insight and experience transfers back to the firm, contributing to our unique knowledge-base. It gives us a strong commercial edge – and we work hard to keep that advantage.

All of this can work to your advantage as well, delivering benefits in quality, experience and cost. Talk to us about how we can help as your Norwegian Partner.

Onsagers helps with European Patent Office applications as part of our ‘full-service’ offering for all IP legal matters. We’ve handled and prosecuted cases in more than 140 different jurisdictions, and employ more technical PhDs than any other law firm in Norway.
