Dag Thrane
Partner / European Patent Attorney

Dag is a physicist and primarily works in technical fields related to sensor technology such as optoelectronics, seismics and flow measurements.

The main focus has been Norwegian clients from startups to major oil companies and research institutes. In some cases the cooperation has lasted for more than 20 years.

In addition to drafting and prosecuting the patent applications he also handles conflicts such as oppositions and assistance in court.

Dag is also part of the delegation representing Norway in the council of the European Patent Institute and as a member of the Disciplinary Committee. He also maintains his interest in the technical field by being part of the optics group the Norwegian Physical Society and combines it with a more artistic approach as an amateur photographer.
