  3. What information and documents are required to be submitted under Section 8 of the Patents Act?

    Section 8 of the Patents Act together with Rule 12 of the Patents Rules requires the applicant to furnish the details of corresponding foreign applications at the Indian Patent Office. Under this requirement, two types of information are required to be submitted at the Indian Patent Office, as stated below:

      1. Information under Section 8 (1):

        Section 8 (1) of the Patents Act requires an applicant to voluntarily submit the details of all the corresponding foreign applications at the Indian Patent Office and keep the Indian Patent Office informed from time to time of the updated status of these applications. The required details include name of country, application number, filing date, status and patent number and date of grant, if available. This information is required in respect of all applications for the same or substantially the same invention as that of the Indian Application and includes divisional/continuation in part applications.

        Briefly, the obligation to file details under Section 8 (1) can be divided into three stages-

        1. Foreign applications filed on or before the filing date in India: As per Rule 12, the period within which the applicant is required to file this information is six months from the date of filing the application in India.
        2. Foreign applications filed after filing the application in India: The period within which the applicant shall keep the Controller informed of the details of such applications is six months from the date of such foreign filing.
        3. Updating the status of all the corresponding foreign applications

        Under Section 8(1), it is pertinent to highlight that the Patents Act prescribes the time limit only for submitting the details of corresponding foreign applications at the Indian Patent Office. While the Patents Act does require the applicant to keep the Controller informed of updated status of all the corresponding applications from “time to time” till grant, it does not prescribe a time limit for the same. The Act accordingly requires the applicant to inform the Controller as and when there is any change in the status / details of the corresponding foreign application but does not require him to update the details of corresponding foreign applications every six months.

      2. Information under Section 8(2):

    If requested by the Controller, details of prosecution of a corresponding application in a foreign country may have to be provided. Such a request is generally made in the examination report. When requested by the Controller, this information must be submitted within six months of the request.

    Briefly, the requirement under Section 8 (2) can be met by submitting:

      1. Examination reports;
      2. Any claim amendments made in corresponding applications, and
      3. Claims as allowed/ granted in corresponding foreign applications.

        Where these documents are not in English, appropriate translation should also be filed.

  4. What happens if an applicant fails to submit the information or document required under Section 8?

    Failure to submit information regarding corresponding foreign applications and details of processing when requested is a ground for both pre- grant and post-grant opposition proceedings before the Indian Patent Office and revocation proceeding before the Courts and the Intellectual Property Appellate Board.

  5. What can be done if an inventor is not available to sign the assignment deed or Form 1 due to change in employment or death?

    In case of unavailability of inventor(s) for signing the assignment deed/ form 1, one of the following documents may be submitted to comply with the requirement:

    1. Notarized/ certified copy of an existing assignment submitted in the priority application/ corresponding application. Also, such existing assignment deed must indicate that the inventor(s) have assigned their rights worldwide.
    2. Notarized/ certified copy of the employment agreement executed by the inventor with the applicant wherein the inventor would have transferred all the rights arising in an invention to the applicant.
    3. A copy of Declaration as to the Applicant’s Entitlement to Apply for and Be Granted a Patent submitted in the PCT application in accordance with Rule 4.17(ii) of the PCT Regulations,.
  6. What is to be done if an application/ patent is re-assigned at a later stage?

    If an application/ patent is re-assigned at a later stage, the new assignment is required to be recorded at the Indian Patent Office. It is mandatory to record any partial/ complete transfer in ownership of an application/ patent at the Indian Patent Office.

    If an assignment is not recorded at the Indian Patent Office, the Patent Office or the Court may not admit the same to be a proof of ownership at a later stage.

  7. What is to be done if a patent is licensed?

    If a patent is licensed, it is mandatory to record this license at the Indian Patent Office. If a license is not recorded at the Indian Patent Office, the Patent Office or the Court may not admit the same to be a proof of share/interest in the patent, at a later stage.
