When a registered Patent Agent fails to renew their registration within the prescribed time, their name is removed from the Register of Patent Agents. However, this removal is not irreversible. The Patents Act, 1970 provides a means to restore registration through Form 23, titled “Application for Restoration of Name in the Register of Patent Agents.”
For professionals who miss the renewal deadline or whose registration lapses due to procedural default, knowing how to correctly file Form 23 is critical to resume practice before the Indian Patent Office.
This blog explains eligibility, statutory timelines, required documents, Controller’s discretion, and practical strategies for successful restoration under Indian patent law.
Legal Framework for Restoration of Patent Agent Registration
Statutory Authority
Section 130 of the Patents Act, 1970 empowers the Central Government to make rules regarding maintenance of the Patent Agents Register.
Rule 115(6) of the Patents Rules, 2003 provides that when a name has been removed for non-payment of the renewal fee, the Patent Agent may apply for restoration.
Form 23 is prescribed under Rule 116 as the statutory format for such an application.
The form is officially titled:
“Application for Restoration of Name in the Register of Patent Agents under Section 130 and Rule 116.”

When and Why Restoration Becomes Necessary
A Patent Agent’s name may be removed from the register for reasons such as:
Non-payment of the five-year renewal fee within the prescribed period (and grace period).
Failure to respond to notices of non-renewal issued by the Controller.
Disciplinary removal, although such cases are governed separately under Section 130(1)(e).
The most common ground is non-payment of renewal fee under Rule 115(4).
Once removed, the agent cannot represent applicants before the Patent Office or use the designation “Patent Agent.” Restoration via Form 23 is thus the sole route to re-enter the Register, provided statutory conditions are met.
Time Limit for Filing Form 23
The restoration application must be filed within 18 months from the date of removal of the name from the register.
Applications filed beyond this limit are time-barred and cannot be entertained.
Example
If an agent’s registration expired on 31 December 2024, and the name was removed from the register on 1 January 2025, Form 23 must be filed by 30 June 2026.
Delays beyond this 18-month window are fatal to restoration.
Who May Apply
Only the person whose name was removed (the Patent Agent themself) can apply in Form 23.
The application may be submitted personally or through a duly authorized representative.
No third party can apply on behalf of the removed agent unless power of attorney and identity proofs are enclosed.
Contents & Structure of Form 23
The official Form 23 can be downloaded from the IP India portal.
Here is what each section requires and how to draft it effectively:
Section | What to include | Practical guidance |
1. Applicant details | Full name, address, nationality, registration number (as previously recorded) | Must match details in the previous certificate of registration |
2. Statement of removal | Date of removal and reason (usually non-payment of renewal fee) | Verify from IPO notice or journal entry |
3. Request for restoration | Formal request to restore name to Register of Patent Agents | State clearly that you have paid renewal and restoration fees |
4. Supporting documents | Copies of payment receipts, renewal reminders (if any), and declaration explaining reason for delay | A well-explained reason helps the Controller exercise discretion favourably |
5. Declaration & signature | Signed statement that the particulars are true to the best of knowledge | Attach self-attested ID proof and recent photograph |
6. Fee details | Amount paid and mode of payment (electronic CBR or IPO receipt) | Verify correct restoration fee under the current Schedule of Fees |
Mandatory attachments:
Copy of earlier Certificate of Registration.
Proof of renewal fee and restoration fee payment.
Explanation letter for non-renewal or late filing.
Procedure After Filing Form 23
Once Form 23 is submitted to the Patent Office (physically or through e-filing):
Examination by Controller
The Controller verifies the form, payment receipts, and reasons stated for non-renewal.Opportunity to be Heard (if required)
If the Controller has doubts or considers refusal, the applicant may be given a hearing opportunity.Decision
If satisfied that the omission to renew was unintentional and there was no undue delay, the Controller may order restoration.
The Controller may impose conditions, such as payment of arrears or compliance requirements.
Re-entry in the Register
On approval, the Patent Agent’s name is re-entered in the Register and published in the Official Journal of the Patent Office.
The Controller also issues a fresh Certificate of Registration.Effect of Restoration
Once restored, the Patent Agent regains all rights and obligations as if their name had not been removed, subject to compliance with the new renewal cycle.
Particular | Rule / Form | Prescribed Fee (Individual) |
Renewal of registration every 5 years | Rule 115(1) | ₹5,000 |
Restoration application (Form 23) | Rule 116 | ₹2,000 |
Renewal fee arrears | Rule 115(4) | ₹5,000 + late fee if applicable |
Total payable at restoration (approx.) | — | ₹7,000 or more, depending on arrears |
Strategic Tips for a Smooth Restoration
Do not delay: File Form 23 as soon as possible after removal; waiting close to 18 months risks rejection.
Provide a genuine reason: Explain clearly that non-payment or lapse was unintentional (e.g., health, travel, financial delay).
Ensure full fee payment: Restoration without renewal fee or arrears is invalid.
Retain proof: Keep all payment receipts, IPO acknowledgments, and correspondence.
Maintain updated address and contact details: So that future renewal reminders reach you on time.
Avoid repeat defaults: Multiple restorations reflect poorly and may influence Controller’s discretion adversely.
Common Pitfalls
Filing after 18 months from removal date - not permissible.
Submitting incomplete payment proof or missing restoration fee.
Vague or unsupported explanation for delay.
Incorrect registration number or address mismatch with IPO records.
Ignoring Controller’s deficiency notice or hearing call - deemed abandonment.
Practical Example
If a Patent Agent registered in 2019 fails to pay the renewal due in 2024, and the IPO removes the name in January 2025, the agent must:
Pay renewal + restoration fees.
File Form 23 by June 2026.
Attach prior registration certificate, explanation, and receipts.
Await Controller’s decision and re-entry notice in the Journal.
Conclusion
Form 23 serves as the lifeline for Patent Agents whose registration lapses due to oversight or procedural delay. By demonstrating bona fide intent and timely compliance, a professional can restore their name and resume practice before the Indian Patent Office.
Meticulous preparation: accurate data, complete payment, and credible explanation, ensures smooth restoration and avoids reputational or professional setbacks.
