Over the course of more than 20 years in the patent industry, he has worked for 5 years as a case handler at Norwegian Industrial Property Office and spent the remaining years as a consultant to research environments and the private sector. During that time he has prepared several hundred patent applications in a variety of technical fields, such as multiphase measurement, optical sensor technology, electronics, silicon technology and software. Dag also has broad experience from consulting on conflicts and rights analysis.
