Interlego AG v Toltoys Pty Ltd

Interlego AG and Toltoys Pty Ltd were parties to litigation concerning the alleged infringement of design rights in a toy brick. The dispute came before the Full Court of the Federal Court of Australia.

The central legal issues before the court were whether the plaintiff, Interlego AG, had established its entitlement to relief for infringement of its registered design, and if so, whether the defendant, Toltoys Pty Ltd, had infringed that design. The court was also required to consider the validity of the registered design.

The court's reasoning focused on the interpretation of the relevant provisions of the Designs Act 1906 (Cth). It examined the requirements for a valid registration of a design, including novelty and originality, and the scope of protection afforded by a registered design. The court applied principles of comparison between the registered design and the allegedly infringing articles, considering whether the essential features of the registered design were reproduced. The court found that the plaintiff had not established infringement of its registered design.

Consequently, the Full Court of the Federal Court of Australia ordered that the appeal be dismissed and the judgment of the primary judge be affirmed.
