Westerberg & Partners is a boutique intellectual property (IP) and dispute resolution firm with one of the largest IP teams among Swedish law firms. It helps clients in identifying, analysing, strengthening, commercialising and protecting their rights - whether based on IP, contracts, treaties, trade secrets or regulatory frameworks. Open mindedness, focus and flexibility are three of their core values.

The IP team represents clients in all aspects of IP (except for patent prosecution), including advisory services, contracts, transactions and corporate work for companies with intellectual assets at its core. It is particularly well-known for its copyright, patent and trademark litigation expertise and portfolio management services.

In commercial dispute resolution, the firm’s significant experience in Swedish and international arbitration has led to its involvement in some of the most complex and challenging disputes, including acting for and against sovereign states in litigation and arbitration over the interpretation of international treaties and in other high-profile disputes.

Westerberg & Partners represents Swedish and international clients, ranging from established giants to start-ups and sovereign states.

The firm is built by friends sharing the same vision: aiming to be the best at what they do.
