Section 11A explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 11A says when an application for a patent is opened to the public. In general it is published after a prescribed period, though the applicant can ask for earlier publication, and a few categories are never published or are published late. Once published, the applicant gets certain rights from the date of publication, although he cannot sue for infringement until the patent is granted. Because publication makes your invention public, it is worth reading before you decide on timing in a patent drafting and filing plan.
No application is ordinarily opened to the public for the prescribed period (11A(1)). The applicant may request earlier publication, and the Controller then publishes it as soon as possible (11A(2)). On expiry of the period every application is published, except those under a secrecy direction, abandoned under section 9(1), or withdrawn three months before the period ends (11A(3)). From publication to grant the applicant has the like privileges and rights as if a patent had been granted, but cannot start infringement proceedings until grant (11A(7)).
Section 11A(1): the waiting period
"Save as otherwise provided, no application for patent shall ordinarily be opened to the public for such period as may be prescribed."
The length of the period is "as prescribed", so it sits in the Patents Rules, 2003, which are not in our sources; no figure is given. Sub-sections (1) to (3) were substituted by the 2005 Amendment Act, with effect from 1-1-2005. The footnote to sub-section (4) records that the earlier wording was "of eighteen months"; that is old wording, and the present text refers to the period "prescribed under sub-section (1)".
Section 11A(2): early publication on request
"The applicant may, in the prescribed manner, request the Controller to publish his application at any time before the expiry of the period prescribed under sub-section (1) and subject to the provisions of sub-section (3), the Controller shall publish such application as soon as possible."
- Who acts: the applicant requests, in the prescribed manner (which includes payment of the prescribed fee, section 2(1)(v)); the Controller publishes.
- When: at any time before the period expires.
- How fast: "as soon as possible". The Act gives no number of days.
- Subject to sub-section (3): applications in the excluded categories are not published even on request.
Section 11A(3): publication on expiry, and the exceptions
"Every application for a patent shall, on the expiry of the period specified under sub-section (1), be published, except in cases where the application— (a) in which secrecy direction is imposed under section 35; or (b) has been abandoned under sub-section (1) of section 9; or (c) has been withdrawn three months prior to the period specified under sub-section (1)."
| Case | Published? | Why |
|---|---|---|
| Ordinary application, period expired | Yes | General rule |
| Secrecy direction under section 35 | Not at this point; see (4) | Defence-related secrecy |
| Abandoned under section 9(1) (no complete specification within twelve months of a provisional) | No | Application is dead |
| Withdrawn three months prior to the end of the period | No | Withdrawal in time |
Withdrawal later than that, on the text, does not take the application out of sub-section (3)(c). Section 11B(4) proviso (i) lets an applicant withdraw at any time before grant, which we cover in the article on section 11B; but the exemption from publication applies only to withdrawal "three months prior to the period specified".
Drafting note. Clause (3)(a) reads "in which secrecy direction is imposed under section 35" and clause (3)(b) reads "has been abandoned"; the grammar of the list is loose, but the meaning is clear.
Section 11A(4): secrecy direction cases
"In case a secrecy direction has been given in respect of an application under section 35, then, it shall be published after the expiry of the period prescribed under sub-section (1) or when the secrecy direction has ceased to operate, whichever is later."
An application held under a secrecy direction is published only when both conditions are satisfied: the prescribed period has expired and the direction has ceased to operate. Whichever comes later governs. Section 35 is covered in our article on secrecy directions.
Section 11A(5): what the publication shows
"The publication of every application under this section shall include the particulars of the date of application, number of application, name and address of the applicant identifying the application and an abstract."
So a published application carries four things: the date, the application number, the name and address of the applicant, and an abstract. Section 10(4)(d) requires the abstract, and the Controller may amend it.
Section 11A(6): biological material and public access
"Upon publication of an application for a patent under this section— (a) the depository institution shall make the biological material mentioned in the specification available to the public; (b) the patent office may, on payment of such fee as may be prescribed, make the specification and drawings, if any, of such application available to the public."
Two separate consequences. First, where a deposit was made under section 10(4)(d), the depository institution makes the material available to the public once the application is published. Second, the patent office "may", on payment of the prescribed fee, make the specification and drawings available. The text does not say how the public asks, and the fee is prescribed; we give none.
Section 11A(7): rights from publication to grant
This sub-section was inserted by the 2005 Act. On and from publication until grant, "the applicant shall have the like privileges and rights as if a patent for the invention had been granted on the date of publication". The first proviso limits it: "the applicant shall not be entitled to institute any proceedings for infringement until the patent has been granted".
The second and third provisos deal with applications "made under sub-section (2) of section 5 before the 1st day of January, 2005": rights accrue from the date of grant, and after grant the patent-holder is only entitled to "reasonable royalty" from enterprises that had made significant investment and were producing and marketing the product before 1 January 2005 and still do on the date of grant, with no infringement proceedings against them.
Flag: these provisos refer to section 5(2), which no longer exists in the Act (section 5 is omitted). They remain in the printed text as a transitional provision. They affect only applications of that earlier category.
Example. Vihaan Aero Pvt Ltd (fictional) files an application for a lightweight drone frame. The prescribed period expires and the application is published with its date, number, applicant's name and address and an abstract. A competitor starts making a frame that appears to fall within the claims, before grant. Under section 11A(7) the company has the like privileges and rights as if the patent had been granted at publication, but it cannot file an infringement suit until the patent is granted. After grant, it can proceed with its rights in the usual way.
What section 11A does not say
- It does not state the length of the waiting period or any fee.
- It does not say what the "privileges and rights" in 11A(7) are, beyond "like" those of a granted patent, subject to the provisos.
- It is silent on damages for acts between publication and grant.
Publication is a disclosure: once published, your invention is public. Our guides on the patent filing timeline put publication in the wider sequence.

Key takeaways
