The patent filing procedure has a time constraint. The patent specification filed can be provisional or complete. If a provisional specification is filed first, then the complete specification needs to be filed at any time within 12 months from the provisional filing date (priority date). If the complete specification is not filed within the prescribed time window, the provisional application lapses.

Once the patent application is filed, the patent application is published within 18 months from the priority date. TimeThe inventor or the assignee needs to make request for examination of the patent application filed to the controller of Indian Patent Office within 48 months from the priority date.

Generally within 12 months from date of filing the request for examination, first examination report is issued by the Indian Patent Office and sent to the inventor or assignee. During the first examination stage, the examiner prepares the examination report incorporating all the objections related to the patent application. The objections are clearly mentioned for an inventor or assignee to understand. The first examination report may either be favourable or adverse to the inventor. If the report is adverse, it normally contains objections related to errors in forms or fees or any objections related to the patentability requirements. Once the first examination report is sent, the inventor or assignee needs to file a response within 6 months.

The inventor can draft a response by amending the application in order to overcome the objection raised in first examination report. Once the response is filed based on the response either second examination report is sent or the inventor  is called for the hearing within 1 month from the date of receiving the first examination report. The patent may be granted or rejected based on that. Another possibility is that based on response to the first examination report, the grant or rejection of the patent application is decided. The inventor can also withdraw the patent application any time after filing of application and before grant of the patent application by filing a request for the same with the requisite fee.
