Dovuro Pty Ltd v Wilkins & Ors

Dovuro Pty Ltd (Dovuro) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the validity of a patent. The dispute centred on whether Dovuro's patent for a method of producing a seed coating formulation was invalid due to a lack of novelty and an insufficient description of the invention. The Full Federal Court had found the patent invalid on both grounds.

The High Court was required to determine whether the Full Federal Court had erred in finding that the patent lacked novelty, specifically in light of prior art that allegedly disclosed the essential features of the claimed invention. Furthermore, the Court had to consider whether the patent specification adequately described the invention in a manner that enabled a person skilled in the art to perform it, or if it was insufficient by reason of ambiguity or lack of detail.

The High Court, in a joint judgment, held that the Full Federal Court had correctly identified the prior art and that the claimed invention was not novel. Their Honours reasoned that the prior art document disclosed all the essential integers of the claims, meaning the invention had been publicly disclosed before the priority date of the patent. Regarding sufficiency, the Court found that while the specification could have been clearer, it did provide sufficient information for a skilled person to perform the invention, and therefore this ground of invalidity was not made out.

Consequently, the High Court dismissed Dovuro's appeal, upholding the Full Federal Court's finding that the patent was invalid due to a lack of novelty.
