Section 142
142. Groundless threats of legal proceedings.—
(1) Where a person, by means of circulars, advertisements or otherwise, threatens a person with an action or proceeding for infringement of a trademark which is registered, or alleged by the first-mentioned person to be registered, or with some other like proceeding, a person aggrieved may, whether the person making the threats is or is not the registered proprietor or the registered user of the trademark, bring a suit against the first-mentioned person and may obtain a declaration to the effect that the threats are unjustifiable, and an injunction against the continuance of the threats and may recover such damages (if any) as he has sustained, unless the first-mentioned person satisfies the court that the trademark is registered and that the acts in respect of which the proceedings were threatened, constitute, or, if done, would constitute, an infringement of the trademark.
(2) The last preceding subsection does not apply if the registered proprietor of the trademark or a registered user acting in pursuance of sub-section (1) of section 52 with due diligence commences and prosecutes an action against the person threatened for infringement of the trademark.
(3) Nothing in this section shall render a legal practitioner or a registered trademarks agent liable to an action under this section in respect of an act done by him in his professional capacity on behalf of a client.
(4) A suit under sub-section (1) shall not be instituted in any court inferior to a District Court.
