What this section says, in plain language
Drafting a patent specification is a technical and legal skill, and a badly drafted one cannot usually be repaired later. For that reason the Act limits who may do this work for others. Section 129 restricts practice: a person who is not registered as a patent agent must not practise, describe himself or hold himself out as a patent agent, and a company or firm cannot present itself as a patent agent either. Section 123 supplies the consequence for breaking that restriction, which after the Jan Vishwas (Amendment of Provisions) Act, 2023 is a monetary penalty adjudicated under Section 124A, with an additional amount for each day a contravention continues.
To be registered, a person must meet the qualifications in Section 126, which include being a citizen of India, being at least twenty-one years old, holding a degree in science, engineering or technology from a recognised university, and passing the patent agent examination or having the prescribed experience in the Patent Office. Names are entered in the register of patent agents kept under Section 125, and Section 127 gives registered agents the right to practise before the Controller and to prepare and sign the documents the Act requires. Rules 108 to 120 deal with the register, the examination, removal and restoration.
The restriction has limits that people often miss. Section 132 preserves the right of an applicant to draft and file his own specification and to appear before the Controller in his own matter. It also allows an advocate who is not a registered patent agent to take part in a hearing before the Controller on behalf of a party, though an advocate who is not registered cannot sign and file documents as a patent agent. So a company can prepare its own application, and a litigating advocate can argue at a hearing, but a consultant who is not registered cannot run a patent filing practice for clients.
For inventors the practical value of this section is protection. Unregistered intermediaries advertise cheap filing packages, file thin specifications with weak or missing claims, and disappear when the first examination report arrives. Before you engage anyone, ask for the agent's name and registration number, check it against the published register, and confirm who will actually sign the forms. The authorisation you sign in favour of an agent is itself a formal document, and it should name the registered professional who is responsible for your matter.
Why this section matters
Inventors and businesses hiring help to file patents, and consultants or firms offering patent services in India.
When choosing who will draft and file your application, and when a firm decides how to describe its services.
A penalty for unregistered persons who practise or hold themselves out as patent agents, including a continuing daily amount.
Applicants get poorly drafted applications with no accountable professional, and unregistered providers face adjudicated penalties.
How it works in practice
A cheap filing that could not be fixed
Kavya Nair, who runs a three-person robotics startup in Kochi, hires a consultant advertising complete patent filing at a low fixed price. The consultant is not on the register of patent agents but describes himself as a patent expert and signs the correspondence. The application is filed with a three-page description and two vague claims. Eighteen months later the examination report raises objections on clarity, sufficiency and inventive step. By then the specification cannot be widened, because the Act does not allow new matter to be added by amendment, and the consultant stops answering calls. Kavya engages a registered patent agent who explains that the disclosure never supported the features that made her arm commercially different. The consultant is exposed to a penalty under Section 123, adjudicated under Section 124A, for holding himself out as a patent agent. That does not restore the lost claim scope. A registration number check at the start would have taken five minutes.
Simplified illustration only. Actual legal outcomes depend on the facts.
Key points to remember
- Only persons registered under Section 125 may practise or describe themselves as patent agents.
- Contravening that restriction attracts a penalty, with an additional amount for each day the contravention continues.
- Since the Jan Vishwas Act, 2023 the penalty is imposed through the adjudication process in Section 124A.
- An applicant may still draft, file and argue his own patent matter without being an agent.
- An advocate who is not a registered agent may take part in a hearing before the Controller, but cannot sign and file as a patent agent.
- Always verify the agent's registration number against the published register before you engage anyone.
Common mistakes and misunderstandings
- Assuming any lawyer can sign and file patent documents. Signing as a patent agent requires registration, even though advocates may appear at hearings.
- Thinking that a company can be registered as a patent agent. Registration is personal to an individual who meets the qualifications.
- Believing that self-filing is prohibited. An applicant is free to prepare and file his own application; the restriction is on acting for others.
- Judging a provider only by price. The cost of a weak specification appears years later, when it can no longer be fixed.

Indian patent law works in two layers. The Act carries the substance and the Rules carry the machinery. Because the layers are amended by different processes and at different times, they are presented in separate blocks instead of being merged into one description.
Forms, deadlines and fees
Forms used under the Patents Rules are prescribed in the Second Schedule. They are revised when the Rules change, so download the current version from the Patent Office website rather than reusing a copy saved earlier.
We do not publish fee amounts. The First Schedule sets them, and they differ by category of applicant, such as a natural person, a startup, a small entity or another applicant, and by the mode of filing. Check the Schedule currently in force before you calculate anything. How Indian patent fees work.

Questions people ask about Section 123
Can I file my own patent application without a patent agent?
Yes. Section 132 preserves the right of an applicant to draft his own specification and to appear before the Controller in his own matter, and many individual inventors and startups do file directly. The restriction in Section 129, backed by Section 123, is on acting or holding yourself out as a patent agent for other people. Before you self-file, be realistic about claim drafting, because the claims decide the scope of protection and cannot be broadened later by adding matter that the original specification did not disclose.
How do I check whether someone is a registered patent agent?
The Patent Office maintains a register of patent agents under Section 125 and publishes the list of registered agents. Ask your service provider for the individual's full name and registration number, then match it against that list, and confirm that the same person will sign the forms filed in your matter. Also check that the authorisation you sign names that person. If a provider avoids giving a registration number or says the paperwork will be signed by someone else you cannot identify, treat that as a warning sign.
What qualifications does a patent agent need in India?
Section 126 sets the conditions. The person must be a citizen of India, have completed twenty-one years of age, hold a degree in science, engineering or technology from a recognised university in India or an equivalent qualification, and either pass the qualifying examination prescribed under the Rules or have the prescribed experience as an examiner or officer in the Patent Office. Registration is completed by paying the fee prescribed in the First Schedule and having the name entered in the register kept under Section 125.
