Our Swedish authorized patent attorneys and European patent attorneys have extensive experience and substantial knowledge of national and European patent law.

A patent firm with highly qualified legal resources

Ström & Gulliksson was founded by Tore Ström and Jonas Gulliksson. From the outset, the business concept of our founders was to integrate commercial law and intellectual property law with patent law, enabling a complete and well-rounded service.

In 2001, the law practice was spun off as a separate company, Advokatbyrån Gulliksson, leaving Ström & Gulliksson as a specialized patent firm.

The collaboration between the two firms has continued ever since. As a client of Ström & Gulliksson, you benefit from our long-standing collaboration with Advokatbyrån Gulliksson.


Ström & Gulliksson is owned by eight partners who also serve as the firm’s management team: Rikard Roos, Björn Andersson, Leif Jörgensson, Jan Nilsson, Erik Bolmsjö, Christian Arkelius, Magnus Berglund and Malin Ahlgren.
