Trade mark similarity and passing off: a common descriptive prefix did not justify interim injunction where the marks differed materially.

In interlocutory trade mark disputes, the impugned mark must be assessed as a whole for visual and phonetic resemblance, the nature of the goods, the class of purchasers, and the impact of any common descriptive or generic element. Applying that approach, the shared prefix derived from "energy" was treated as descriptive and insufficient, by itself, to establish exclusivity. The suffixes "JEX" and "JASE" were found materially dissimilar, and the different product forms and trade channels reduced any likelihood of confusion. Prima facie deception or passing off was not shown, so temporary injunction was not warranted and the refusal of interim relief was upheld.

Issues: Whether the mark "ENERJASE" was deceptively or phonetically similar to the registered mark "ENERJEX" so as to justify interim relief for infringement and passing off.

Analysis: The governing test for infringement and passing off required comparison of the marks as a whole, with particular attention to their visual and phonetic resemblance, the nature of the goods, the class of purchasers, and whether the common element was descriptive or generic. The Court noted that the rival products were different in form, presentation, and trade channels, one being an allopathic syrup and the other an ayurvedic capsule, and that the shared prefix was an abbreviation of the common word "energy" which had become descriptive and common to the trade. On the materials available at the interlocutory stage, the suffixes "JEX" and "JASE" were found to be materially dissimilar and unlikely to confuse purchasers.

Conclusion: The mark "ENERJASE" was not shown prima facie to be deceptively or phonetically similar to "ENERJEX", and interim injunction was not warranted.

Final Conclusion: The refusal of temporary injunction was upheld because the appellant failed to establish a prima facie case of infringement or passing off and the appellate court found no reason to interfere with the exercise of discretion by the court below.

Ratio Decidendi: In interlocutory trade mark matters, an injunction will not be granted unless the impugned mark, assessed as a whole, is prima facie likely to deceive or confuse the relevant purchasing public, and a common descriptive or generic element cannot by itself found exclusive proprietary claim.
