Our approach

Onsagers gives professional, clear-cut advice. 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 through IP aligned with the business strategy. We know that protecting IP is expensive and we strive to focus on what really adds value to your business in the long term.

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

We strive for quality over quantity in all aspects of IP

IP Competence

We employ more technical PhDs than any other IP law firm in Norway along with a highly skilled legal department. We have extensive knowledge of most industries including an in-depth knowledge in the pharmaceutical field, bio-tech, oil & gas and shipping.  Having industry teams consisting of engineers and lawyers ensures that all relevant aspects are covered, and brings benefits in quality, cost and strategic advice.

When it comes to drafting and prosecution, Onsagers understand what is relevant in our home markets and when co-ordinating international patent families. We have employed more ex-Norwegian Industrial Property Office (NIPO) attorneys than any other IP firm. We have a growing presence in Germany, the UK and Sweden as well as in Norway. Our team includes numerous European Patent Attorneys with vast experience in guiding patent applications through the PCT and EPO examination processes. We work closely with an extensive local and international IP network that has been built over 70 years, built on trust and mutual benefit.

We also understand how to defend and enforce your IP rights. No other Norwegian firm can match our expertise in EPO Oppositions and Appeals, which has been developed alongside handling of other aspects of IP disputes and, more importantly, guiding disputes toward a successful resolution. Onsagers is uniquely placed to add value in a competitive IP landscape, including facing new opportunities and challenges arising from the Unitary Patent and Unified Patent Court.


Onsagers’ clients benefit from clear-cut, pragmatic advice and a personal, ‘hands-on’ approach to managing cases.  We’ve developed a singular approach to the way we work. This prizes predictability over uncertainty, and cost-efficiency over ambiguity.
