Patent agent — Intellectual Property Rights I Notes

Patent agent

Drafting a patent is part law, part science — a claim badly worded can lose a fortune. So the Act creates a special professional, the patent agent, and reserves the work to those who qualify. When one petitioner argued this monopoly violated his freedom of trade, the court had to weigh s.126 against Article 19(1)(g).

Who is a patent agent?

A patent agent is a person registered under the Act who is entitled to practise before the Patent Office — drafting specifications, filing applications and prosecuting them (ss.125–132).

Qualifications — s.126. A person may be registered as a patent agent if he:

• is a citizen of India;
• has completed the age of 21 years;
• holds a degree in science, engineering or technology from a recognised university; and
• has passed the qualifying examination prescribed (or, formerly, was an existing practitioner). (An advocate’s qualification alone is no longer sufficient; the science-degree and exam requirements were tightened.)

Functions — s.127. A registered patent agent may:

• practise before the Controller and the Patent Office;
• prepare and draft patent specifications and other documents; and
• do all things connected with a patent application on a client’s behalf.

The restriction — s.129. No person, other than a registered patent agent (or the applicant himself), may practise, describe himself as a patent agent, or draft specifications for reward. This reservation was upheld as a reasonable restriction on the freedom of trade.

Patents Act, 1970, s.126(1): “A person shall be qualified to have his name entered in the register of patent agents if he fulfils the following conditions, namely — (a) he is a citizen of India; (b) he has completed the age of 21 years; (c) he has obtained a degree in science, engineering or technology from any university… and… has passed the qualifying examination prescribed for the purpose.”

In Simple Terms: A patent agent is a qualified professional — Indian citizen, 21+, science/engineering degree, passed the exam — who alone may draft patent specifications and act before the Patent Office for reward. The rule reserving this work to registered agents is a valid limit on freedom of trade, because patent drafting needs technical skill.

🧩 WORKED EXAMPLE — the constitutional challenge

Facts. A petitioner challenges s.126, arguing that reserving patent-agent work to science graduates who pass an exam violates his Article 19(1)(g) right to practise a profession.

Rule. Article 19(6) permits reasonable restrictions in the public interest, including professional-qualification requirements.

Apply. Patent drafting requires technical competence; requiring a science degree and an exam is a reasonable, non-arbitrary restriction protecting applicants from incompetent drafting.

Conclusion. s.126 is constitutionally valid; the restriction on who may practise is reasonable under Article 19(6).

Case Laws

• Anvita Singh v Union of India (Delhi HC, 2012) — struck down the rule requiring a minimum 50% in the viva-voce of the Patent Agent Examination as arbitrary and excessive. It did not decide the validity of the s.126 qualification conditions themselves (citizenship, age 21+, science degree, qualifying exam), which remain the governing requirements for entry on the register.
• Bishwanath Prasad Radhey Shyam v Hindustan Metal Industries (1979) — patent work rests on genuine technical competence, the rationale for reserving agency to qualified persons.
