Nichia Corporation v Arrow Electronics Australia Pty Ltd (No 2)

Nichia Corporation, an applicant, sought a determination of the priority date of certain claims in its Australian Standard Patent Number 720324, from Arrow Electronics Australia Pty Ltd, the respondent. The case was heard in the Federal Court of Australia. The dispute centred around the interpretation and entitlement to priority dates of specific claims in the patent, particularly in relation to a light emitting device and its components. The crux of the matter was whether certain claims of the patent were entitled to earlier priority dates based on specific technical descriptions and elements.

The court was tasked with interpreting the language of the patent claims and determining the precise priority dates for each claim, considering the technical specifications and the relevant prior art. This involved a detailed examination of the claims in the patent and the applicant's submissions regarding the technical features and their significance. The court had to decide if the claims met the criteria for the earlier priority dates based on the technical content and the applicant's submissions.

The court concluded that the claims were entitled to the priority dates as specified in the orders. It found that the applicant had successfully demonstrated that certain claims were entitled to earlier priority dates due to the technical content and the specific descriptions provided. The court ordered that the respondent pay the applicant's costs of and incidental to the determination of the separate question, with those costs to be taxed and paid forthwith. This decision was based on the applicant's success at the interlocutory hearing and the need for the respondent to bear the costs associated with the determination of the priority dates.
