Our patent attorneys are registered to practise before the Australian, New Zealand and Singapore Patent Offices and they instruct patent attorneys registered before the Indian Patent Office (IPO) on all aspects of Indian patent prosecution.
The government agency responsible for grant of patent rights in India is the Indian Patent Office”.
|Key prosecution event||Deadline|
|Paris Convention Filing:||12 months from earliest claimed priority|
|PCT National Phase Entry:||31 months from earliest claimed priority|
|Substantive examination request:||48 months from earliest claimed priority|

Indian national phase applications must be filed by 31 months from the earliest claimed priority date. This time limit is non-extendible. View filing requirements for National phase applications in India.
An Indian Convention application can be validly filed within 12 months from filing a priority application filed according to the Paris Convention for Protection of Industrial Property. View filing requirements for Convention applications in India.
An IPO examiner checks if the application satisfies the formal requirements needed for the grant of a filing date. The applicant will be given a defined period by the IPO to remedy any deficiencies with the application, otherwise the application is considered withdrawn.
Substantive examination does not occur automatically. The applicant must file a request for substantive examination and/or pay the substantive examination fee within 48 months from the earliest priority date. Expedited examination is also available when the applicant is a startup or small entity.
The patent application is examined for novelty (absolute), inventive step, patentable subject matter and industrial application.
The following subject matter is not patentable:
If the examiner objects to the application on one or more grounds (eg the invention is not novel), the examiner issues a First Examination Report (FER). The applicant can respond and have the application (with or without amendment) re-examined and reconsidered. The applicant has 6 months from the issuance date of the FER to file a response, otherwise the application is deemed to be abandoned. The time for reply may be extended by 3 months. In some of the cases, the FER is followed by an oral hearing, which is similar to an examiner interview to resolve further objections after filing a response to the FER. It is compulsory to attend the oral hearing and to subsequently file written submissions.
Any person can file a pre-grant opposition at the IPO in order to challenge the grant of the application, any time after the publication of the application but before the grant of the patent.
Indian divisional applications must be filed before the parent application is withdrawn or granted. The parent application should have lack of unity issues, and the divisional application should not mirror the claims of the parent application.
Once the examiner is satisfied that there are no outstanding issues and all fees have been paid, the IPO will grant the patent. If the required fees for grant and printing are not paid in due time, the application shall be deemed to be withdrawn. The IPO issues and sends the Letters Patent to the applicant or their attorneys.
India is a signatory to the Budapest Treaty on the International Recognition of the Deposit of Micro-organisms for the Purposes of Patent Procedure. The deposit must be made before filing the application. If the depository institution and the file number of the culture deposit are not stated in the application at the time of filing the application, this information must be submitted within 2 months from a request by the examiner. The application will not be published until this information is submitted.
