Australia's Extension of Time Provisions for Patents Have Their Limits (and May Soon Have More)

Key Takeaways

• APO requires proven error, not deliberate delay.
• Recent case rejected 12‑month EOT for payment fees.
• Consultation proposes automatic short extensions or 3‑month filing limit.
• Current law permits unlimited EOT, even up to ten years.
• Comments deadline is 2 April 2026.

Summary

Australia’s extension of time (EOT) provisions for patents are praised for flexibility, but a recent Australian Patent Office (APO) decision underscores that applicants must demonstrate a genuine error or omission, not a deliberate choice, to qualify. The case of MossHydro AS highlighted the rejection of a 12‑month EOT request after the applicant’s own staffing decision was deemed intentional. IP Australia is now consulting on possible reforms, including automatic short extensions and a three‑month filing window for post‑deadline EOT requests. Submissions close on 2 April 2026.

Pulse Analysis

Australia’s extension of time (EOT) framework has long been a competitive advantage for patent filers, offering a discretionary safety net when deadlines are missed due to genuine mistakes. Unlike the stringent "despite due care" standard in Europe, the Australian system allows the Commissioner to grant extensions if the applicant can show they exercised reasonable care. This flexibility supports complex biotech and fintech portfolios that often juggle multiple international filings, but it also places a burden on counsel to meticulously document any alleged error.

The recent APO ruling in MossHydro AS v Marine Harvest ASA illustrates the limits of that flexibility. The applicants attempted to treat the lay‑off of the staff member responsible for fee payment as an inadvertent error, yet the Hearing Officer classified the decision as deliberate, denying a 12‑month EOT. The decision reinforces that merely citing internal disruptions is insufficient; applicants must provide clear, contemporaneous declarations linking the omission to the missed deadline. Consequently, patent practitioners are likely to tighten internal controls, maintain detailed logs, and consider proactive extensions before deadlines lapse.

IP Australia’s March 2026 consultation signals a possible shift toward more regimented EOT rules. Proposals such as a single automatic paid extension of up to six months and a three‑month cut‑off for post‑deadline requests aim to curb abuse and reduce uncertainty for third parties. While industry groups like OzKat warn that tighter limits could hinder legitimate applicants, the consultation invites broader stakeholder input before any legislative change. The outcome will influence not only filing strategies but also the overall predictability of the Australian patent landscape, making the upcoming comment period critical for innovators and IP counsel alike.
