ITC Limited v. Controller of Patents, Designs and Trademarks

Relevant Acts and provisions

Patents Act, 1970

Section 3(b)Section 83(e)

Provisions considered: Sections 3(b) and 83(e) of the Patents Act, 1970, read with Article 47 of the Constitution of India.

Brief facts

ITC appealed against an order refusing its patent application for a heater assembly to generate aerosol, a device generating nicotine aerosol through a chemical reaction rather than electrical heating. The Controller refused the application under Section 3(b), holding that the invention causes serious prejudice to human health and is contrary to public order and morality, relying on a research council white paper, Article 47 of the Constitution and other material never disclosed to the appellant.

Issues before the Court

1. Does Section 3(b) require identification of the invention's primary or intended use, rather than a generalised assessment of possible harm, before refusal on grounds of serious prejudice to health?
2. Does reliance on documents undisclosed in the examination report or hearing notice violate natural justice?
3. Can Section 83(e) and Article 47 justify treating the grant of a patent as equivalent to authorising commercial sale?

Court's findings

The Court held that the Controller had misunderstood the invention by assuming it was necessarily limited to tobacco-derived nicotine substrates, without engaging with the appellant's case that the claims were substrate-neutral.

The Court further held that reliance on a white paper and other statutes cited for the first time in the impugned order, without prior disclosure to the appellant, violated natural justice.

The Court observed that Section 3(b) is founded on an intent principle directed at the primary or intended use of an invention, not an effect or harm principle, and that a bare, unreasoned assertion that nicotine-related inventions cause serious prejudice to health, absent scientific evidence, could not sustain refusal. It held that a patent confers only an exclusionary right and not a right to sell, so Section 83(e) and Article 47 were misapplied in treating the grant of a patent as equivalent to permitting commercial exploitation.

Decision

Impugned order set aside and the application remanded for fresh consideration by a different officer, with no opinion expressed on the merits.
