Swiss Life Asset Managers Nordic – Acquisition of a prime logistics property from a fund managed by Savills Investment Management
We advised a fund managed by Swiss Life Asset Managers Nordic in its acquisition of a logistics property in Hyvinkää from a fund managed by Savills Investment Management. In addition to advising on the transactional aspects, we also advised on the financing of the acquisition as well as in designing an appropriate international acquisition structure and addressing relevant tax implications. The property serves as the central warehouse in Finland for Ahlsell, a leading Nordic technical wholesaler, which has been leasing the property since its construction. The state-of-the-art logistics centre was originally built in 2002 and has undergone several improvement projects over the years. The latest extension, completed in 2024, added around 11,000 square meters of new storage area to the property, bringing the total lettable area to 47,000 square meters. The property has been developed with a strong emphasis on energy efficiency with on-site solar power and renewable district heating. The sustainability features of the property were also further optimised and the asset just received BREEAM Excellent certifications in both BREEAM New Construction and BREEAM In-Use.

BMW AG – Enforcement of BMW’s trademark and design rights
We successfully represented BMW in an exceptionally long dispute over whether the spare rims sold by the defendant and the hub caps included in them infringed BMW’s trademark and design rights. The Market Court found that the sign used by the defendant caused a likelihood of confusion with BMW’s trademarks. The defendant had used the sign on the hub caps and in the marketing of the hub caps and rims, leading the Market Court to find that the defendant had infringed BMW’s trademark rights. The defendant admitted to infringing BMW’s Community design but denied the related injunction claim. However, the Market Court found that there was no particular reason to refrain from issuing an injunction. The Market Court prohibited the defendant from continuing to infringe BMW’s trademarks and Community design and ordered the defendant to alter or destroy the products and marketing materials that infringed BMW’s rights. Furthermore, the Market Court ordered the defendant to pay BMW EUR 70,000 in reasonable compensation and EUR 80,000 in damages for the trademark infringements, as well as EUR 7,000 in reasonable compensation and EUR 8,000 in damages for the design right infringement. The amounts can be considered exceptionally high in Finland. Additionally, the Market Court ordered the defendant to pay a significant portion of BMW’s legal costs with interest on late payment. In its decision of 11 March 2025, the Supreme Court of Finland did not grant the defendant leave to appeal, and also decided that there was no need to seek a preliminary ruling from the Court of Justice of the European Union. Thus, the Market Court’s judgements (MAO:494/18 and 517/2023) are final. In addition to the main dispute, BMW demanded in a separate proceeding that one of the defendant’s trademark registrations be revoked. A total of three separate legal proceedings were conducted in the Market Court regarding the revocation. The defendant’s trademark registration was ultimately revoked.

Foodiq – Restructuring proceedings
Castrén & Snellman’s Attorney Christer Svartström acted as the administrator in the restructuring proceedings of Foodiq Oy, which began on 11 March 2024. Foodiq is a unique future food focused company that develops and produces plant and milk-based products for both the private and public sectors. The company’s largest shareholder is a Swedish investment company focusing on FoodTec, Nicoya AB. The majority of creditors approved the draft restructuring programme in expedited proceedings after restructuring proceedings that lasted just under a year. The District Court of Helsinki affirmed the restructuring programme including the one-day payment programme on 10 March 2025 and appointed Attorney Christer Svartström as the supervisor of the programme. In cooperation with the parties, they found an effective and quick restructuring solution for the company, avoiding a long-term programme and allowing the company to focus on its core business. The restructuring programme was financed by investments made by the company’s investors. At the same time, the one-day programme provided a better outcome for creditors compared to a longer programme. The implementation of the restructuring programme ended successfully on 28 March 2025.
