With a blue-collar background in the car industry, after graduating from Chalmer’s University of Technology (Gothenburg, Sweden) Magnus started to work as a patent examiner at the Swedish Patent Office in Stockholm, where he stayed from 1991 to 1994 (including a short period at the Swedish Court of Patent Appeals). 

In 1994 he moved to private practice and to Madrid (Spain), where he has been living ever since. Before co-founding BALDER in 2012, Magnus worked for four of the most important Spanish IP firms, at one of which he directed the foreign patent department. In all of his previous positions, Magnus mainly dealt with prosecution before foreign patent offices, with a special focus on the European Patent Office (EPO). He was also involved with different one-stop shopping programs for Latin America. 

Magnus was one of the very first professionals in Spain to become a European Patent Attorney by passing the European Qualifying Examination (EQE). This, in combination with his language skills (although his working languages are only English, Spanish and Swedish, Magnus also understands German and French, the two other official languages of the EPO), is one of the reasons for why Magnus has become one of the favorite patent professionals for IP conscious Spanish companies in the electro-mechanical field. 

And not only for those wishing to obtain quality patents, but also for those desiring to have their competitors’ patents revoked. Magnus started early to handle oppositions before the EPO and its Boards of Appeal, and has by now acquired a unique experience and an excellent track record. 

Magnus deals with a wide range of technologies in the electro-mechanical field, including renewable energies, industrial machinery, medical devices and automobile components. 

Apart from his work related to the filing and prosecution of patent applications and oppositions, Magnus is frequently involved with litigation, advising clients and acting as an expert before Spanish Courts, providing opinions on infringement and validity. Magnus has also successfully completed the CEIPI (Centre d’Études Internationales de la Propriété Intellectuelle, Strasbourg, France) diploma course in European patent litigation. 

Magnus also participates actively in external and internal tutoring programs for the next generation of European Patent Attorneys.

When not working, Magnus enjoys hiking, walking his dogs, boxing, and having a couple of cold beers. In his spare time he is also trying to learn the Greek language.
