Patent Agents, Controller and Information Relating to Patents

Updated 11 October 2026 · Fact-checked

A patent agent is a person registered under the Patents Act, 1970 to practise before the Controller. Section 126 sets the qualifications, section 129 bars unregistered practice, section 123 fixes the fine, and under section 153 a person who requests prescribed information in the prescribed manner and pays the prescribed fee is entitled to it.

Understand Patent Agents, Controller and Information Relating to Patents

A patent is granted by the Patent Office, which works under the Controller. Section 74 provides for one patent office, with a head office and branch offices at places the Central Government specifies. The office has a seal. Section 75 stops its officers and employees from acquiring any right or interest in a patent issued by that office while they hold their posts. Inheritance or bequest is the only exception.

Filing and pursuing a patent is technical work. So the Act regulates who may do it for others. A patent agent is a person whose name is entered in the register of patent agents. Section 126 lists the qualifications. Section 127 gives the rights. Section 129 restricts who may practise or call themselves patent agents.

Section 129 has two limbs. An individual, alone or in partnership, must be registered. In a partnership, all partners must be registered. A company or other body corporate cannot practise or hold itself out as patent agents at all. The Explanation says practise includes applying for or obtaining patents in India or elsewhere, preparing specifications or other documents under this Act or foreign patent law, and giving non-scientific, non-technical advice on validity or infringement of patents.

The Act also protects some persons. Under section 132 an applicant may draft his own specification and appear or act before the Controller. An advocate who is not a patent agent may take part in a hearing before the Controller on behalf of a party. Section 131 lets the Controller refuse to recognise certain agents, and requires refusal for a person with no residence or place of business in India.

Section 153 deals with information. A person who makes a request to the Controller in the prescribed manner, for prescribed information about a specified patent or application, is entitled to it on paying the prescribed fee. Section 117E gives the Controller the right to appear in certain High Court proceedings.

Key rules to remember

Qualifications for registration (s 126(1)): Indian citizen + age 21 completed + science/engineering/technology degree from a University established under law in India (or equivalent specified by Central Government) + (passed the qualifying examination OR 10 years as examiner/Controller functions under s 73, now ceased) + prescribed fee paid; All of (a), (b), (c) and (d) must be met. Within (c), the exam route and the ten-year route are alternatives.
Saving for old agents (s 126(2)): Registered before the Patents (Amendment) Act, 2005 → may continue or be re-registered on paying the prescribed fee; Applies despite sub-section (1).
Restriction on practice (s 129): Individual/partnership: must be registered (all partners registered). Company or body corporate: cannot practise or hold itself out as patent agents.; Practise includes applying for patents, preparing specifications or documents, and non-technical advice on validity or infringement.

How to solve Patent Agents, Controller and Information Relating to Patents questions

Most questions ask for qualifications, restrictions, penalties or the right to information. Use the same frame for each.

1Identify the issue: registration (s 126), practice restriction (s 129), penalty (s 123), rights (s 127), refusal of recognition (s 131) or information (s 153).
2State the provision in plain words with the section number.
3List the conditions or elements separately, such as the four conditions in s 126(1).
4Apply each condition to the facts. Note who the person is: individual, partner, company, applicant, advocate.
5Check the savings in s 132 and s 126(2) before concluding.
6State the consequence, such as the fine under s 123 or the Controller's power under s 131.
7Close with a one-line conclusion that answers the question asked.

Quickest way: Who may act, who may not

When to use it: For short fact-based questions on whether someone can practise before the Controller.

Ask: is the person registered? If yes, s 127 rights apply.
If a company or body corporate: it cannot practise as patent agents (s 129(2)).
If unregistered: is he the applicant himself, or an advocate at a hearing? Then s 132 saves him.
Otherwise it is a breach of s 129, punishable under s 123.
For information requests: written request in prescribed manner plus fee, then s 153.

Common mistakes in Patent Agents, Controller and Information Relating to Patents

Saying a company can be registered as a patent agent.
Students think of agent firms as companies.
Fix: Section 129(2) bars any company or body corporate from practising or holding itself out as patent agents. Firms need all partners registered.
Stating that section 129 punishes with imprisonment.
Many offences in other Acts carry jail terms.
Fix: Section 123 provides only a fine: up to ₹1,00,000 first offence, up to ₹5,00,000 later offences.
Thinking a person without a science degree can be registered by passing the exam.
Students remember the exam but forget the degree condition.
Fix: Section 126(1)(c) requires a degree in science, engineering or technology (or specified equivalent) in addition to the exam or ten-year route.
Treating every advocate as barred from appearing before the Controller.
Students read s 129 without s 132.
Fix: Section 132(b) allows an advocate who is not a patent agent to take part in a hearing before the Controller on behalf of a party.
Writing that section 153 gives free information to the public.
The word entitled suggests an absolute right.

Worked examples

Example 1

Sunrise Patent Services Private Limited, a company, advertises itself as patent agents and files patent applications for clients. Rohan, a graduate engineer who has not passed the qualifying examination, is its director. Examine the legal position.

Show the solution

Provision: section 129(2) says no company or other body corporate shall practise, describe itself or hold itself out as patent agents.
Facts: the company advertises as patent agents and files applications, which is practising under the Explanation to s 129 (applying for or obtaining patents).
Even if Rohan were registered, s 129(2) bars the company itself from practising or holding itself out as patent agents. Rohan is also not qualified for registration under s 126(1) without passing the exam or meeting the ten-year route.
Consequence: s 123 applies. Fine up to ₹1,00,000 for a first offence and up to ₹5,00,000 for a second or later offence.
Recognition: s 131(1)(d) lets the Controller refuse to recognise a company if a director or manager is a person the Controller could refuse under s 131(1). That applies to Rohan only if he falls within clauses (a) to (c), for example after conviction under s 123 or if he works wholly or mainly as an agent for his employer. The facts do not establish this.

Answer: The company has contravened section 129(2) and is punishable with a fine under section 123, up to ₹1,00,000 for a first offence. Section 131(1)(d) would let the Controller refuse to recognise it only if Rohan is a person the Controller could refuse under section 131(1)(a) to (c); the facts do not show this.

Example 2

Meera, a 24-year-old Indian citizen with a B.Tech degree from an Indian University, wants to be entered in the register of patent agents. She has not passed the qualifying examination. She asks whether she may draft and file a patent specification for her own invention. Advise.

Show the solution

Registration: s 126(1) needs citizenship, age 21, a science, engineering or technology degree, the fee, and either the qualifying examination or ten years as examiner or Controller.
Meera meets citizenship, age and degree. She lacks the exam, and the ten-year route is not available to her.
So she is not yet qualified for registration.
Own invention: s 132(a) says nothing in the Chapter prohibits an applicant from drafting any specification or appearing or acting before the Controller.
Therefore she may act for herself, but she may not do so for others as a patent agent.

Answer: Meera cannot be registered until she passes the qualifying examination and pays the prescribed fee. She may still draft her own specification and act before the Controller as the applicant under section 132(a).

Exam tips

Learn section 126(1) as a checklist of four conditions, and remember the exam and ten-year alternatives.
Write the fine amounts from section 123 exactly: ₹1,00,000 and ₹5,00,000.
Always mention the section 132 saving when the question involves an applicant or advocate.
Cite the section number beside each point. ICSI-style answers reward provision, analysis, then conclusion.
For section 153, write the three elements: prescribed request, prescribed matters, prescribed fee.
