If you are eyeing Indonesia for your PCT National Phase entry, you have likely heard about the 31-month rule, which is calculated from the earliest priority date.
But here is the key question:
“Miss the deadline — and you’re out?”
The answer is: Not necessarily.
Unlike some jurisdictions, Indonesia offers a second chance. The Directorate General of Intellectual Property (DGIP) accepts late entry, up to 12 months after the 31-month deadline, provided:
- You pay an additional official fee, and
- Submit a written explanation justifying the delay.
This flexibility helps businesses avoid losing rights over paperwork or timing errors, but the longer you wait, the greater the risk.
Our advice? Don’t cut it close. However, if you really have to, be aware of your options and the extra requirements.
