The applicant can file a request to withdraw the patent application any time before the grant of a patent.
When the request to withdraw the application is filed within 15 months from the earliest priority application date, the application will not be published in the official journal of the Indian Patent Office.
Further, the Indian Patent Office refunds 90% of the official fee paid for request for examination, if the application is withdrawn by the applicant before the issuance of the first examination report/ office action.
