Britax Childcare Pty Ltd v Infa-Secure Pty Ltd (No 3)

Britax Childcare Pty Ltd brought an action against Infa-Secure Pty Ltd, alleging infringement of two innovation patents and two standard patents. The dispute arose from the use of a technology in the manufacture of car seats. The matter was heard in the Federal Court of Australia.

The court was required to decide several legal issues, including whether the relevant date for determining infringement was the date of publication of the divisional application or the date of the priority claim, and whether omnibus claims in the standard patents were valid. The court also needed to determine whether the claims in the innovation patents were directed to an invention that was not new or innovative, as claimed by Infa-Secure.

The court found that the relevant date for determining infringement was the date of publication of the divisional application, as this was the date from which the invention was disclosed to the public. The court also held that the omnibus claims in the standard patents were valid, as they were not invalid for lack of clarity or precision. Finally, the court found that the claims in the innovation patents were valid and that Infa-Secure had infringed them. The court rejected Infa-Secure's argument that the invention was not new or innovative, finding that it was a valid and useful improvement over existing technology.

The court ordered Infa-Secure to pay damages to Britax for infringement of the innovation patents, and to cease and desist from any further infringement of the standard patents. The court also ordered Infa-Secure to deliver up any articles that were subject to the infringement. The case highlights the importance of carefully considering the relevant dates for determining patent infringement, and the need for clear and precise patent claims.
