Repipe Pty Ltd v Commissioner of Patents

Repipe Pty Ltd brought an appeal against the Commissioner of Patents over the revocation of their patents concerning methods and systems for providing and receiving information for risk management in the field. The central legal issue was whether the patents in question constitute a 'manner of manufacture' as defined by s 18(1A)(a) of the Patents Act 1990 (Cth). The court examined whether the inventions claimed in the patents were patentable subject matter, considering the technical contributions of the patents. Repipe argued that the patents disclose technological inventions where computer technology is integral and significant, whereas the Commissioner contended that the patents merely describe a business method or scheme implemented using computers.

The court found that the patents, despite their reliance on specific software applications, do not disclose a technical means by which ordinary computing functions are performed. The claimed inventions were characterised as a business method rather than a technical advance, as they primarily use computers to share and complete documents in a more convenient manner. The specifications of the patents admit that the claimed inventions can be implemented using any software application, indicating that the inventions lack a specific technical contribution. The court concluded that the patents do not meet the criteria for patentability as they do not constitute a manner of manufacture.

The court's decision was grounded in the principle that a claimed method implemented by a computer does not become patentable merely because it is executed by a computer. The inventions, while potentially useful, do not offer a technical advance or contribution to computing. The court found that the claims and specifications do not define or disclose any specific technical means by which the ordinary computing functions are performed. As a result, the patents were held to be invalid, and the appeal was dismissed. The parties were directed to confer and prepare a minute reflecting these reasons within 14 days, with any disputes to be resolved by written submissions.
