What this rule requires, step by step
When a patent is granted, the Patent Office issues a certificate of grant. That certificate is a piece of paper, and paper goes missing. It is left behind when a founder exits, destroyed in a fire or a flood, misplaced during an office move, or held by a person who will not hand it back. Rule 132 deals with exactly that situation. It allows the patentee to apply to the Controller for a duplicate of the patent, and it tells the applicant what the request must show.
The request is made in writing on the general request form prescribed in the Second Schedule, currently Form 31, with the fee set out in the First Schedule. Because the Controller is being asked to issue a second original, the request has to be supported. The applicant explains what happened to the certificate: that it was lost or destroyed, or why it cannot be produced. The Controller must be satisfied on that account before issuing the duplicate. A bare request with no explanation is likely to be met with a query rather than a certificate.
It is important to understand what a duplicate is not. It does not create a fresh patent, does not restart or extend the twenty-year term, and does not change a single thing about the scope of the claims or the identity of the owner. The legal state of the patent lives in the Register of Patents, not in the certificate. The duplicate simply replaces a document that has gone missing so that the owner has something formal to produce.
That leads to a practical point most people miss. For many purposes a duplicate certificate is not what you actually need. If a bank, a court, a customs authority or a foreign counterpart wants proof of who owns the patent today and whether it is in force, a certified copy of the register entries under Section 72, obtained through Rule 133, is the better document, because the register reflects assignments, licences and renewals as they stand. The duplicate is the right request when the certificate itself is required, for example where a licence or a transaction document calls for production of the grant certificate.
Why this rule matters
Patentees, assignees and company secretaries who need to produce a grant certificate that has been lost, damaged or withheld.
Any time after grant, usually when a transaction, a court filing, a funding round or an audit calls for the original certificate.
A discretionary power in the Controller to issue a replacement certificate once he is satisfied about what became of the original.
Nothing is lost in law, because the patent survives without its certificate, but the owner may be unable to satisfy a bank, buyer or court that wants the document in hand.
How it works in practice
A Coimbatore textile MSME rebuilds its paperwork
Sundara Weaves Pvt Ltd, a Coimbatore textile MSME, holds a patent on a low-tension yarn feeder. In 2024 water from a burst tank ruins a store room, and the grant certificate is among the papers destroyed. Two years later the company is negotiating a technology transfer with a Surat manufacturer whose lawyers ask to see the certificate before signing. Sundara Weaves files a request on the general request form with the prescribed fee, sets out plainly how the certificate was destroyed, and attaches a short statement from its plant manager together with the insurance surveyor's list of damaged records. The Controller is satisfied and a duplicate is issued. Separately, on its advisor's suggestion, the company also obtains a certified copy of the register entries, because the buyer's real question is not what the 2019 certificate said but whether the patent is in force today and free of any recorded licence. The two documents answer two different questions, and the transaction closes with both.

Key points to remember
- Rule 132 covers only the replacement of a lost, destroyed or unproducible patent certificate.
- The request goes on the general request form in the Second Schedule with the fee in the First Schedule.
- The Controller must be satisfied about what happened to the original before issuing a duplicate.
- A duplicate changes nothing about the term, scope or ownership of the patent.
- For proof of current ownership and status, a certified copy of the register under Rule 133 is usually the more useful document.
Common mistakes and misunderstandings
- Believing that losing the certificate weakens or endangers the patent. The patent stands on the register and on the renewal record, not on the certificate.
- Asking for a duplicate when the real need is proof of current status. That is a Section 72 certified copy obtained under Rule 133.
- Filing the request with no explanation of how the certificate was lost. The Controller's power depends on being satisfied about the circumstances.
- Expecting the duplicate to carry today's date and therefore a fresh term. It replaces the earlier certificate and nothing more.
Connected provisions
Rules are made under the Act, not alongside it. That is why the connected sections appear in a block of their own. Reading the section tells you why the procedure exists, and reading the rule tells you the steps, forms and periods that put it into effect.
Forms, deadlines and fees
- Form 31 (check the current Second Schedule)
Where a form is required, the Second Schedule to the Patents Rules prescribes it. Superseded versions circulate widely online, so download the current form from the Patent Office and check it against the rule before use.
Where a fee is payable under this provision, the figure comes from the First Schedule. Categories of applicant are charged at different rates, and electronic filing is treated differently from paper filing, so an accurate number can only come from the Schedule in force on the day you file.

Questions people ask about Rule 132
Is my patent still valid if I have lost the certificate?
Yes. A patent exists because it was granted and entered in the Register of Patents, and it stays in force while renewal fees are paid under Section 53. The certificate is evidence of the grant, not the grant itself. Losing it creates a practical problem rather than a legal one: you may struggle to satisfy a bank, investor or court that wants a document to look at. Rule 132 exists precisely so that the gap can be filled without anyone suggesting that the underlying right has been affected.
What proof do I need to get a duplicate patent certificate?
Enough to satisfy the Controller about what became of the original. In practice that means a clear written account of the loss, destruction or inability to produce the certificate, signed by someone who knows the facts, supported by whatever documents exist: a fire or flood report, a police complaint for a theft, an insurance surveyor's list, or a company record of an office move. There is no fixed checklist in the rule. The test is whether the Controller is satisfied, so the more specific and verifiable the account, the smoother the request.
How is a duplicate patent different from a certified copy?
A duplicate replaces the grant certificate itself and is issued under Rule 132. A certified copy is an authenticated copy of a document on the Patent Office file or of entries in the register, and is obtained under Section 72 through Rule 133. If a counterparty wants to see the certificate, ask for the duplicate. If the question is who owns the patent now, whether renewals are paid, or whether a licence is recorded, the certified copy of the register answers it and is generally what lawyers and lenders actually want.
