Rule 94 of the Patents Rules, 2003
Alteration of address
Lets a patentee or applicant have a name, address or address for service corrected or updated in patent office records and the register.
Official legal text
The verbatim statutory text of this provision is reproduced from the official source and checked by our legal reviewer before it is published here. Until that check is complete for this page, read the exact wording directly from the official source linked below — it is the only version that governs.
Treat this page as a guide. The provision as officially published, along with the Gazette notifications that apply to it, remains the governing text and overrides any simplification here.
What this rule requires, step by step
Businesses move offices, change their names after a merger, and switch patent agents. The Patent Office does not learn of any of this automatically. Rule 94 provides the route for having an alteration of a name, an address or an address for service made in the register and in the records relating to an application or a patent. The request is made to the Controller with the fee prescribed in the First Schedule.
The address for service is the address the Controller uses for every official communication, including examination reports, hearing notices and opposition papers. If it is stale, correspondence goes to an address nobody reads. Missed communications rarely produce sympathy later, because the office has done what the law requires by writing to the address on record. Many abandoned applications trace back to nothing more dramatic than an unnotified change of address.
The Controller may ask for proof before altering an entry. A simple change of premises may need little more than the request itself, while a change of name after a merger or a conversion of a partnership into a company will need documents showing that the new name belongs to the same legal person. Where the change is really a transfer to a different legal entity, this rule is the wrong route: that is a registration of title under section 69, which requires Form 16 and proof of the assignment.
One practical point often missed is coverage. The register and the office records are organised patent by patent and application by application, so a request should identify every application and patent number affected. A company with forty pending applications that notifies a new address on one file may find the other thirty-nine still pointing at the old office.
Why this rule matters
Applicants and patentees who move, rename or restructure, and anyone changing patent agents or address for service.
As soon as an address, name or address for service changes, and before the next official communication is due.
A right to have the records and the register corrected, subject to proof, and a practical duty to keep the address for service current.
Official letters go to the wrong place, deadlines are missed without the applicant ever seeing the notice, and applications can be treated as abandoned.
How it works in practice
A shifted office and a missed examination report
Anjali Menon runs a design consultancy in Kochi with four pending patent applications filed while the firm worked from a shared workspace. The firm moves to its own premises and, in the rush, updates its website, GST records and bank details but not its patent office records. Seven months later the first examination report is issued and sent to the address for service on file, which is the old workspace. The mail is returned. Anjali only discovers the report when she checks the application status online with weeks left of the response period. Her agent immediately files requests under Rule 94 to alter the address and address for service on all four applications, listing each application number, and pays the prescribed fee. The response to the examination report is filed just in time. The near miss is instructive: the alteration request costs little and takes minutes, while the cost of an application abandoned for want of a reply is the loss of the invention to the public domain.
Simplified illustration only. Actual legal outcomes depend on the facts.
Key points to remember
- Rule 94 covers alteration of a name, an address or an address for service in the register and office records.
- File the request with the Controller, paying the fee set out in the First Schedule.
- The address for service is where every official communication is sent, so it must stay current.
- The Controller may require proof, especially for a change of name.
- A transfer to a different legal entity is a registration of title under section 69, not an alteration.
- List every application and patent number affected so no file is left with the old details.
Common mistakes and misunderstandings
- Assuming the Patent Office picks up a new address from a later filing on one case. Each file must be updated.
- Using an address alteration to record what is really a transfer of ownership to a new company, which needs a title registration instead.
- Leaving the address for service as a former agent's office after changing agents, so official letters continue to go to someone with no instructions.
Connected provisions
This page explains a rule of the Patents Rules, 2003. A rule does not stand on its own; it works out a duty or a power that the Patents Act, 1970 has already created. The parent sections are listed separately so you can read the source of that authority.
Forms, deadlines and fees
- There is no statutory last date for requesting an alteration, but it should be filed as soon as the change happens, because official communications continue to go to the address on record until it is changed.
Open the deadline calculator — and have every date confirmed against the current Rules before you rely on it.
Any official fee connected with this provision is fixed by the First Schedule to the Patents Rules, not by the provision itself. The amount depends on who the applicant is and on whether the filing is made online or on paper, so no figures are reproduced here. How Indian patent fees work.

Case law is added slowly and deliberately. A summary is drafted, checked against the reported judgment and then reviewed before publication, because a wrong case note can mislead a reader badly. No summary for this provision has reached publication yet. How case notes are prepared.
Questions people ask about Rule 94
What is an address for service and why does it matter?
It is the address in India that the Patent Office uses for all official correspondence on an application or a patent, and it is often the address of the patent agent rather than the applicant. Every examination report, hearing notice and opposition document goes there. If it is out of date, you may never see a communication that starts a deadline running, and the office is entitled to treat service at the recorded address as good service.
Can I change the name of the applicant using this rule?
Only where the legal person is the same and just the name has changed, for example after a corporate name change or a conversion. You will normally need documents proving that the old and new names belong to the same entity. If the right has actually moved to a different legal person, by assignment, merger of a different kind, or transmission, the correct route is registration of title under section 69 on Form 16, with the underlying document produced as proof.
Do I have to file a separate request for every patent and application?
The records are maintained file by file, so the request must identify each application and patent number that should be updated. Whether that is done through one consolidated request or several depends on how the Patent Office and its e-filing system handle it at the time. The safe practice is to prepare a complete list of your applications and patents before filing, and to verify afterwards that each file shows the new details.
