Protecting your technology

Patents

We specialise in a complete range of patent-related services to protect and maximise the value of your intellectual property in Europe and beyond.

With you every step of the way

From patent drafting through to prosecution and grant, our award-winning team of attorneys have been representing clients in all proceedings before the European Patent Office (EPO), the Norwegian Industrial Property Office (NIPO), and other national offices for decades.

We’re also called as expert witnesses in patent litigation cases and have served as expert judges in Norway’s national courts.

We handle hundreds of cases every year, and have many years of experience winning opposition and appeal proceedings before the EPO and the Norwegian courts, too.
