Descriptive word marks and bona fide descriptive use defeated passing off and interim infringement restraint.

Descriptive word marks such as "LOSORB", "LO-SORB" and "LOW ABSORB" were treated as common English expressions indicating lower oil absorption, and exclusive protection was unavailable without clear secondary meaning acquired through long, undisturbed use. The respondent's use of "WITH LOW ABSORB TECHNOLOGY" was held to be descriptive, supported by its own prominent house mark, and not likely to cause deception, so the passing off claim failed. Registration was only prima facie evidence of validity, and at the interlocutory stage the court could examine whether the registration was vulnerable. The statutory defence of bona fide descriptive use therefore defeated the infringement claim and interim restraint.

Issues: (i) whether the expressions "LOSORB", "LO-SORB" and "LOW ABSORB" were descriptive marks incapable of exclusive appropriation absent sufficient acquired distinctiveness, and whether the respondent's use of "WITH LOW ABSORB TECHNOLOGY" amounted to passing off; (ii) whether the appellant's registered marks could sustain an infringement action and interim injunction in the face of the statutory defences of descriptive use and the limited evidentiary value of registration at the interlocutory stage.

Issue (i): whether the expressions "LOSORB", "LO-SORB" and "LOW ABSORB" were descriptive marks incapable of exclusive appropriation absent sufficient acquired distinctiveness, and whether the respondent's use of "WITH LOW ABSORB TECHNOLOGY" amounted to passing off.

Analysis: The expressions in dispute were held to be common English descriptive phrases indicating the character of the product, namely lower oil absorption. A descriptive expression is not ordinarily entitled to monopoly protection unless it has, through long and undisturbed use, acquired a secondary meaning so that the public unmistakably associates it with one source. The use shown by the appellant was relatively short, the marks were applied for on a proposed-to-be-used basis, and the material did not establish that the expression had become exclusively identifiable with the appellant. The respondent's packaging prominently displayed its own mark and used the disputed words only as part of a descriptive sentence, reducing the possibility of deception or confusion.

Conclusion: The marks were not shown to have acquired sufficient distinctiveness to justify exclusive monopoly, and the passing off claim failed.

Issue (ii): whether the appellant's registered marks could sustain an infringement action and interim injunction in the face of the statutory defences of descriptive use and the limited evidentiary value of registration at the interlocutory stage.

Analysis: Registration of a mark is only prima facie evidence of validity, and where the mark is inherently descriptive, the court may examine whether the registration is vulnerable while deciding interlocutory relief. The statutory scheme permits descriptive use of expressions indicating kind, quality, intended purpose or other characteristics of goods, and the court held that the respondent's use fell within that protection. Evidence of distinctiveness after registration was not treated as sufficient in the infringement suit to cure the absence of distinctiveness at the relevant stage. Since the respondent's use was descriptive and accompanied by its own prominent house mark, the appellant could not establish a sustainable infringement claim for interim restraint.

Conclusion: The infringement action was not made out at the interlocutory stage, and the statutory defence of descriptive use applied in favour of the respondent.

Final Conclusion: The appeal failed because the disputed expressions were treated as descriptive, non-exclusive word marks, and the respondent's use was held to be protected descriptive use rather than actionable passing off or infringement.

Ratio Decidendi: A descriptive word mark cannot be monopolised unless it has acquired a clear secondary meaning through long and undisturbed use, and even a registered mark may be met by a statutory defence where the impugned use is bona fide descriptive use indicating the character or quality of the goods.
