Sandvik Intellectual Property AB v Quarry Mining & Construction Equipment Pty Ltd

The matter before the court involved a dispute between Sandvik Intellectual Property AB and Quarry Mining & Construction Equipment Pty Ltd, with the central issue being the validity and infringement of a patent held by Sandvik. The case was heard in the Federal Court of Australia. Sandvik sought to enforce its patent, which covered a system for processing material, against Quarry Mining, alleging infringement through the supply of equipment that enabled the use of the patented system. Quarry Mining, in turn, challenged the validity of the patent on multiple grounds, including novelty, inventive step, the best method known to the inventors, usefulness, and the basis of the alleged infringement.

The court was tasked with determining whether the patent met the statutory criteria for novelty, inventive step, and usefulness, as well as assessing the validity of the infringement claim. Specifically, the court had to consider whether the patent system was novel in light of prior use, whether it was obvious to someone skilled in the field, if the best method known to the inventors was disclosed, whether the invention was useful, and if Quarry Mining's actions constituted infringement through inducement and instruction. Additionally, the court examined if the sale and promotion of goods by Quarry Mining, without a warning of the patent infringement, constituted misleading and deceptive conduct under competition and consumer law.

In its decision, the court found that the patent did not meet the criteria for novelty, as prior use established by Quarry Mining demonstrated the system's existence before the patent application. The court also found that the system was obvious to a person skilled in the relevant art and that the patent did not embody the best method known to the inventors. Furthermore, the court held that the invention was not useful as claimed and that Quarry Mining's actions did not constitute infringement as a primary tortfeasor without a prior act of infringement. The court concluded that the promotion and sale of the goods by Quarry Mining did not amount to misleading and deceptive conduct, as there was no representation or suggestion that the goods infringed the patent. Consequently, the court dismissed Sandvik's claims, revoked the patent in part, and ordered the parties to submit written costs submissions.
