Passing off and trade name protection: wide trademark definitions can support interim injunctions despite different business activities.

A passing off action may extend to a deceptively similar trade name because the statutory definition of mark is wide enough to include names, so jurisdiction can lie in the District Court. Delay, waiver, acquiescence or estoppel do not automatically defeat interlocutory relief; they are weighed against the strength of the prima facie case and require clear acquiescence. The statutory defence of bona fide use of one's own name is unavailable where an artificial person knowingly adopts a word to trade on another's goodwill. Even where business activities differ, a strong prima facie case for interim injunction exists if the name has acquired secondary meaning, confusion or deception is likely, and balance of convenience favours protection of established goodwill.

Issues: (i) Whether the District Court had jurisdiction under the trade marks statute to entertain a passing off suit based on use of a trade name; (ii) whether delay, waiver, acquiescence or estoppel disentitled the plaintiffs to interlocutory relief; (iii) whether the adoption of the word as part of the corporate name was bona fide or protected as use of one's own name under the statutory defence; and (iv) whether a prima facie case for interim injunction was made out despite differences in business activity.

Issue (i): Whether the District Court had jurisdiction under the trade marks statute to entertain a passing off suit based on use of a trade name.

Analysis: The statutory definition of mark included a name, and the definition of trade mark was wide enough to encompass trade name and business name. The passing off provision was therefore treated as covering disputes arising from use of a deceptively similar trade name, not merely cases of direct product mark infringement. On that construction, jurisdiction lay only before the District Court having jurisdiction to try the suit.

Conclusion: The District Court had jurisdiction to entertain the suits.

Issue (ii): Whether delay, waiver, acquiescence or estoppel disentitled the plaintiffs to interlocutory relief.

Analysis: The lapse of time after notice of incorporation did not, by itself, amount to consent or a licence creating a new right in the defendants. In a strong passing off case, delay is weighed against the strength of the prima facie claim and does not necessarily bar injunction. Mere delay also does not substitute for the clear acquiescence required to defeat equitable relief.

Conclusion: The plaintiffs were not disentitled to interim relief on the ground of delay, waiver, acquiescence or estoppel.

Issue (iii): Whether the adoption of the word as part of the corporate name was bona fide or protected as use of one's own name under the statutory defence.

Analysis: The corporate defendants were artificial persons, and the factual setting showed deliberate adoption of the impugned word with knowledge of the plaintiffs' reputation. The statutory defence of bona fide use of one's own name was therefore unavailable. The use was held to be calculated to trade on the plaintiffs' goodwill rather than an innocent surname use.

Conclusion: The adoption was not bona fide and the statutory defence failed.

Issue (iv): Whether a prima facie case for interim injunction was made out despite differences in business activity.

Analysis: The evidence showed long and extensive goodwill, secondary meaning, and public association of the word with the plaintiffs' group. The common field of activity test was not treated as an absolute prerequisite; the real question was likelihood of confusion or deception and resulting damage. The defendants' recent adoption of the name, the overlap in some business objects, and the risk of passing off justified restraint. Balance of convenience also favoured protection of the established goodwill.

Conclusion: A strong prima facie case for interim injunction was made out.

Final Conclusion: The interim injunction protecting the plaintiffs' goodwill and restraining use of the impugned corporate name was upheld, and the appeals failed.

Ratio Decidendi: In a passing off action, a wide statutory definition of mark and trade mark can encompass trade names, and where a name has acquired secondary meaning and public goodwill, the absence of identical business activity does not preclude interlocutory protection if the impugned adoption is likely to cause confusion or deception.
