Aristocrat Technologies Australia Pty Ltd v Commissioner of Patents

Aristocrat Technologies Australia Pty Ltd (Aristocrat) sought leave to appeal to the High Court of Australia from a decision of the Full Federal Court. The dispute concerned the patentability of a gaming machine that incorporated a novel feature: a "feature game" that could be triggered by a player achieving a certain outcome during the base game. The Commissioner of Patents had refused Aristocrat's patent application on the grounds that the invention was not a manner of new manufacture within the meaning of s 6 of the Statute of Monopolies, and therefore not a patentable invention. The Full Federal Court upheld the Commissioner's decision.

The High Court was required to determine whether the gaming machine, as described in Aristocrat's patent application, constituted a manner of new manufacture. This involved considering whether the invention was a practical application of scientific or technical knowledge, and whether it produced a useful result. The central question was whether the invention, by providing a new and improved method of playing a game on a gaming machine, fell within the scope of patentable subject matter.

The High Court, in a joint judgment, found that the invention was indeed a manner of new manufacture. Their Honours reasoned that the invention was a practical application of technical knowledge to produce a useful result, namely an improved gaming experience. The court distinguished the invention from mere schemes or abstract ideas, emphasizing that it involved a tangible and functional improvement to a machine. The legal principle applied was that inventions that provide a practical and useful method or process, even if related to entertainment, can be patentable if they involve a physical product or a tangible improvement to an existing product.

The High Court granted Aristocrat leave to appeal and allowed the appeal, setting aside the orders of the Full Federal Court and remitting the application to the Commissioner of Patents for grant.
