UbiPark Pty Ltd v TMA Capital Australia Pty Ltd (No 2)

UbiPark Pty Ltd brought an action against TMA Capital Australia Pty Ltd, TMA Technology Pty Ltd and Zipby Pty Ltd in the Federal Court of Australia. The dispute centred on patent infringement, unjustified threats of infringement proceedings, and patent validity. The primary patent in question, the 335 Patent, relates to a system, method, and computer program for controlling access to restricted areas, such as car parks. The plaintiff, UbiPark, alleged that the defendants had infringed upon this patent and made unjustified threats of infringement proceedings against UbiPark and its customers. The defendants, in turn, argued that the plaintiff's technology did not infringe upon the 335 Patent and that the patent was invalid on various grounds.

The legal issues before the court included the construction of specific claim integers, whether UbiPark's technology infringed the relevant claims, and the validity of the 335 Patent. The court had to determine the meaning and scope of particular claim elements, particularly those related to signal strength and criteria determination. Additionally, the court assessed whether TMA Capital had established infringement by UbiPark, and whether the 335 Patent was valid, considering arguments about the manner of manufacture, inventive step, and utility of the invention.

The court found that UbiPark's technology did not infringe the 335 Patent. The analysis of claim integers indicated that UbiPark's system operated differently from the patented system, particularly in how it determined entry criteria based on signal strength. The court concluded that the defendants had not proven infringement by UbiPark. Regarding the validity of the patent, the court determined that the 335 Patent was valid. The court rejected arguments that the invention was not a manner of manufacture, lacked an inventive step, or was not useful. The evidence and arguments presented by UbiPark were insufficient to establish the invalidity of the 335 Patent.

The court dismissed the invalidity claim and rejected the defendants' claims for additional damages. The court ordered the parties to propose agreed minutes of orders within seven days, with a deadline for filing and serving minutes of proposed orders if no agreement was reached within fourteen days. The decision highlighted the importance of precise claim construction and the need for clear evidence to support allegations of patent infringement and invalidity.
