Trade marks and unfair competition

Within: Trade marks and unfair competition

Hamburg-based IP boutique Harmsen Utescher belongs to the most established firms on the market. Portfolio management is a particularly big focus, but the team also has longstanding experience in the defence of trade marks at courts and at the authorities. Karin Sandberg defended Bell in preliminary ruling proceedings at the ECJ around the interpretation of EU regulations regarding geographical indications, specifically the amendment of the specification Schwarzwälder Schinken (Black Forest ham) so that the cutting and packing of the product also takes place in the area of origin. In a highlight relating to EU law, Martin Kefferpütz represented Ferrero in proceedings now at the EJC surrounding the question of the nullity of a community design due to the rights to an earlier trade mark. Till Lampel acted for Roxtec International in a dispute at the Higher Regional Court in Hamburg concerning the protection of trade marks in the sealing solutions sector. Rainer Kaase successfully secured the enforcement of the registered trade mark Immunostad for Stada at the EJC. Automobiles Citroën, Intersnack and Jack Wolfskin are among its other clients.
