Prior user and interim injunction in trademark disputes require a strong prima facie case before exclusive protection is granted.

In a passing off and trademark dispute, interlocutory restraint on use of identical or highly similar marks was found unjustified because prior user was not clearly established on the available material. Advertisements, invoices and dealer letters did not conclusively prove uninterrupted commercial use, and the evidence was insufficient to support exclusive interim protection for either side. The court applied the need for a strong prima facie case, balance of convenience and risk of irreparable prejudice at the temporary injunction stage, and set aside the injunction, leaving the dispute to be resolved in the suit or before the Registrar without interim restraint.

Issues: Whether a temporary injunction restraining use of the disputed trade marks should continue in a passing off and trademark dispute, and whether prior user had been established on the material available at the interlocutory stage.

Analysis: The parties were competing in the same field with identical or highly similar marks, so the decisive question was prior user. The material relied on for the respondents, namely advertisements, invoices and dealer letters, did not conclusively establish uninterrupted commercial use of the marks in the manner required to justify an injunction. In an interlocutory matter affecting business activity, a strong prima facie case had to be shown, and the court had also to consider balance of convenience and the risk of irreparable prejudice. The material was insufficient to sustain a finding that exclusive interim protection should be granted to either side.

Conclusion: No temporary injunction was warranted in favour of either party.

Final Conclusion: The interlocutory injunction order was set aside and the dispute was left to be worked out in the suit or before the Registrar, without interim restraint operating against either side.

Ratio Decidendi: In a trademark dispute at the interim stage, where prior user is not clearly established and the evidence is inconclusive, temporary injunction should not be granted unless a strong prima facie case and the other interlocutory equities clearly justify such protection.
