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 section says, in plain language
The Patent Office keeps a formal list of the people allowed to practise as patent agents, and section 125 is the source of that duty. The register carries each agent's name, address, the qualification on which registration was granted, the registration number and the date of entry. Rule 108 sets out the particulars that must appear. The register may be kept in electronic form, and the electronic version has the same legal standing as a paper book, which is why the Patent Office is able to publish a searchable list online.
The register exists so that the public can check a simple but important fact: is this person actually allowed to do this work. Under section 127, only a registered agent has the right to practise before the Controller. Under section 123, practising as a patent agent without registration is a contravention. The register turns those rules into something a first-time applicant can verify in a few minutes, without needing to understand the rest of the chapter.
Names enter the register after a person meets the qualifications in section 126 and clears the process in rules 109 to 113. Registration is kept alive by paying the fee prescribed in the First Schedule at the intervals set by rule 115. Names leave the register under section 130, for reasons ranging from a simple request to non-payment or misconduct, and can come back through restoration. Rule 118 covers changes of name or address, and rule 120 provides for publication of the list of registered agents in the Official Journal.
For an inventor or a startup, the register has a practical use at exactly one moment: before handing over the invention. Ask for the agent's registration number, check it against the published register, and then sign the authorisation. This matters because a firm or a company cannot itself be a registered agent. Whoever signs your papers before the Controller has to be a named individual whose entry you can find.
Why this section matters
Every applicant choosing a professional, every registered agent whose entry must stay current, and the Patent Office which maintains the record.
Before appointing an agent, and each time an agent's details, qualification or standing changes.
A public, official record of who may practise, and an obligation on agents to keep their entry accurate and their registration in force.
An applicant may hand a valuable invention to someone with no standing before the Controller, and an agent whose entry lapses loses the right to act.
How it works in practice
A Bengaluru founder checks a consultant before signing anything
Ananya Rao runs Kestrel Robotics Pvt Ltd in Bengaluru and has a warehouse navigation invention ready to file. A consultant approaches her offering to draft and file the application at a low fixed price, and describes himself as an IP expert. Before sharing the design notes, Ananya asks a single question: what is your patent agent registration number. The consultant says his firm handles the filing and a colleague signs. Ananya looks up the published register of patent agents, finds no entry in the consultant's name, and asks who the individual on record will be. It turns out the firm intended to route the paperwork through an agent who would never meet her or read the technical file. Ananya instead engages a registered agent she can verify by number, signs an authorisation in that agent's name, and keeps a note of the registration details in her IP file. The whole check took fifteen minutes and saved her from an unverifiable chain of responsibility.

Key points to remember
- The Controller must maintain a register of patent agents; rule 108 lists the particulars it has to contain.
- The register may be kept in electronic form and is published, so anyone can check whether a person is registered.
- Only individuals appear on it. A company or firm cannot be a registered patent agent.
- Registration is kept alive by paying the fee prescribed in the First Schedule at the intervals set by the rules.
- Entries are removed under section 130 and can be restored; changes of address are recorded under rule 118.
- The register is the practical proof behind sections 123, 127 and 129.
Common mistakes and misunderstandings
- Believing that a consultancy or law firm can itself be entered in the register. Registration belongs to a named individual, never to an entity.
- Assuming that anyone who says IP attorney or IP consultant is a registered agent. The title is not controlled; the register is.
- Thinking an entry, once made, lasts forever. It depends on the prescribed fee being paid and on the agent continuing to be qualified.
- Forgetting to tell the Patent Office about a change of address. Official communications go to the address on record, and a missed letter can mean a missed deadline.

Questions people ask about Section 125
How do I check whether someone is a registered patent agent in India?
Ask for the person's patent agent registration number and match it against the register of patent agents maintained by the Controller, which the Patent Office publishes. The entry shows the name, address, qualification and date of registration. If the person cannot give a number, or the number belongs to somebody else who will never actually handle your file, that is worth knowing before you disclose your invention or sign an authorisation.
Can a company be registered as a patent agent under section 125?
No. The register records individuals only. Section 129 separately bars a company or other body of persons from practising or describing itself as a patent agent. A firm may of course employ registered agents, and those individuals sign and appear in their own names. So when you engage a firm, make sure you know which registered individual is on record for your application, because that is the person the Patent Office will deal with.
What details does the register of patent agents contain?
Rule 108 sets the particulars. In practice the entry shows the agent's name, address, the qualification on which registration was granted, the registration number and the date of registration, with later changes recorded as they are notified. Because the register may be maintained electronically, these details are searchable. Agents are expected to keep the entry current under rule 118, since the Patent Office serves communications on the address that appears there.
Does removal from the register stop an agent from working on my case?
Yes. The rights given by section 127 belong to registered agents, so once a name is removed the person cannot act before the Controller until it is restored. Your application does not lapse because of this, but the authorisation on record becomes useless. You would appoint another registered agent and file a fresh authorisation, and you should immediately check what deadlines are running on the file.
