Colin CM Moore Pty Ltd v Sivathasan

The Federal Court of Australia heard a dispute between Colin CM Moore Pty Ltd, the owner of several patents, and Sivathasan, a licensee of those patents. The crux of the dispute was whether the licence agreement between the parties included an implied term that the patents would remain current and valid. Colin CM Moore Pty Ltd argued that such a term was necessary to give business efficacy to the contract, while Sivathasan contested the existence of this implied term.

The legal issues that the court had to resolve were whether a term implying that the patents would remain current and valid was necessary to give business efficacy to the licence agreement and how to interpret the licence in light of the listed patents. The court had to consider the terms of the licence, the nature of the patents, and the commercial context in which the agreement was made.

The court found that an implied term that the patents were, and would remain, current was necessary to give business efficacy to the licence agreement. The court reasoned that the purpose of the licence was to grant Sivathasan the right to use the patented technology, which would only be of value if the patents remained valid. The court held that it was implicit in the contract that the patents would remain current and enforceable, as this was necessary for the licence to achieve its purpose. The court also noted that the construction of the licence agreement and the listed patents supported the implication of such a term. The court's decision was based on the necessity of the implied term to give business efficacy to the contract and the commercial context in which the agreement was made.

The court ordered that an implied term that the patents were, and would remain, current was incorporated into the licence agreement. This decision reinforced the importance of implied terms in ensuring the effectiveness of contractual agreements and highlighted the need for careful consideration of the terms and context of such agreements.
