Radburg Pty Ltd v Chiropedic Bedding Pty Ltd

Radburg Pty Ltd (the applicant) sought leave to appeal to the High Court of Australia against a decision of the Full Federal Court. The dispute concerned the validity of a patent held by Chiropedic Bedding Pty Ltd (the respondent) for a mattress. The applicant argued that the patent was invalid due to a lack of novelty and an inventive step, and that the respondent had engaged in misleading and deceptive conduct in relation to the patent.

The High Court was required to determine whether the Full Federal Court had erred in finding that the patent was valid and that there had been no misleading or deceptive conduct. Specifically, the court considered whether the Full Federal Court had correctly applied the principles of patent law regarding novelty and inventive step, and whether its assessment of the evidence concerning the alleged misleading conduct was sound.

The High Court granted leave to appeal and ultimately allowed the appeal, finding that the Full Federal Court had erred in its assessment of the patent's validity. The court held that the patent lacked novelty and an inventive step, as the prior art disclosed the essential features of the invention. Furthermore, the court found that the respondent had engaged in misleading and deceptive conduct by representing that its mattress was patented when it was not. The High Court therefore ordered that the patent be revoked and that the respondent pay the applicant's costs.
