National Starch & Chemical Company v Commissioner of Patents

In the case of National Starch & Chemical Company v Commissioner of Patents, the primary issue before the court was whether the delegate of the Commissioner of Patents properly exercised his discretion in denying National Starch an extension of time to serve evidence in support of its opposition to the grant of a patent. The patent in question related to a probiotic composition designed to enhance microbial colonisation of the gastrointestinal tract of animals. The dispute arose from National Starch’s request for a three-month extension of time to submit its evidence, which was denied by the delegate, leading to National Starch seeking judicial review of the decision.

The court was tasked with examining the legal principles governing the extension of time for serving evidence in opposition proceedings under the Patents Act. The relevant statutory provisions, particularly Regulation 5.10, confer a broad discretion on the Commissioner to extend time, provided certain conditions are met. The court needed to determine whether the delegate correctly applied these principles and whether his decision was reasonable and lawful. This involved assessing the delegate’s consideration of various factors, including the adequacy of the applicant’s reasons for the delay, the nature and significance of the evidence yet to be served, and the interests of all parties involved.

The court found that the delegate’s decision was not unreasonable. The delegate had correctly identified the relevant legal principles and had carefully considered the factors pertinent to the grant of an extension of time. The delegate noted that while National Starch had provided some reasons for its delay, such as difficulties in obtaining expert evidence and publication dates, these reasons were not entirely satisfactory. The court upheld the delegate’s conclusion that the evidence provided did not adequately justify the delay and that the interests of the patent applicant and the efficient administration of the Patent Office weighed against granting the extension. Consequently, the court found that the delegate’s decision was a proper exercise of discretion.

The court ordered that the delegate’s decision be set aside, and the application for an extension of time be remitted to the Commissioner for reconsideration by a different delegate. Additionally, the second respondents were ordered to pay the applicant’s costs associated with the application.
