Onsagers AS

Onsagers AS is a leading full-service specialised IP firm and IP strategy adviser in Norway, acting globally with our dedicated international IP team.

With 70 years of practice, Onsagers is one of the longest-established, largest and leading IP firms in Norway. Our objective is to be your privileged partner for the protection, management and exploitation of your intellectual property. Through open dialogue and clear-cut advice, combined with modern technology, updated services and a cost-conscious approach, Onsagers offers premium quality IP support.

We prepare, manage and secure European Patent Office (EPO) applications as part of our full-service offering for all IP legal matters. As Norway’s largest top-tier IP law firm, we have worked on some of the world’s biggest, highest-profile and most complex IP litigation cases.

We have handled and prosecuted cases in over 140 different jurisdictions and we employ more technical PhD graduates than any other law firm in Norway. All this gives us an unrivalled knowledge base and technical capability.

But these are not the only reasons clients instruct us to handle their EPO applications. We have also developed a singular approach to the way we work. This promotes predictability over uncertainty and cost-efficiency over ambiguity.

The Onsagers approach

Onsagers gives professional, clear-cut advice with a practical, no-nonsense approach. The firm has an innovative outlook and its dynamic and proactive team of professionals provides up-to-date services.

Our approach to intellectual property is to deliver value aligned with the business strategy. We know that protecting intellectual property is expensive and, accordingly, we always focus on things that really add value to the bottom line in the long run.

Our professionals always take pride in understanding their clients’ individual and business needs, and in providing quality services in a timely manner at competitive prices.

IP competence

We employ more technical PhD graduates than any other IP law firm in Norway and have a highly competent legal department. We have extensive knowledge of most industries and particular in-depth knowledge of the pharmaceuticals, bio-tech, oil and gas, and shipping industries. Having industry teams consisting of engineers and lawyers ensures that all relevant aspects are covered, and brings quality, cost and strategic benefits.

By employing more former Norwegian Patent Office examiners than any other Norwegian IP firm, we can guarantee that we know what matters when it comes to prosecuting our clients’ applications. We also work closely with our local and international IP network that has been built over 70 years on trust and mutual benefit.

Hands-on

Onsagers’ clients benefit from clear-cut, pragmatic advice and a personal, ‘hands-on’ approach to managing cases.

International IP experts in Norway

Onsagers’ dedicated international IP team offers a one-stop shop, where attorneys at law and European patent attorneys with extensive international experience work in close collaboration.

Our international team has comprehensive experience in trademark and patent prosecution, enforcement, including customs seizures, passing off and unfair competition cases, as well as trademark and patent infringement and validity cases, some of which have attracted international attention. We will give you the best professional and cost-efficient advice for your intellectual property in Norway.

Our team members’ vast experience has been gained from working at the Norwegian Industrial Property Office, as well as from representing Norway at WIPO, the EPO and Nordic Baltic IP Committees. This ensures that our insight into Norwegian IP practice remains current and that we can provide efficient advice and elaborate the best strategy for your IP rights.
