Publication & Substantive Examination

After the patent application is submitted and all its formality requirements are declared complete by the Directorate General of Intellectual Property (DGIP), the DGIP will proceed with the following steps:
 
Publication: The application will be published for 6 (six) months, during which period any interested third party may file an opposition. 

• Though the current publication process is already faster than before, an accelerated publication can still be requested with an additional official fees.

Note:

• PCT national phase applications are published after the WIPO international publication (previously within 6 months).
• Application with acceleration of publication will be published at the earliest 3 months from the filing date (previously 6 months).
• Applications claiming Convention Priority are not eligible for accelerated publication.

 
Substantive Examination: The substantive examination will be conducted based on the timing of the request as follows:

In addition, the following points should be noted:
The request for substantive examination must be submitted no later than 36 (thirty-six) months from the Filing Date. The request must be accompanied by the applicable official fees. Failure to submit a request for substantive examination within the specified period will result in the patent application being deemed withdrawn.
