Trade mark comparison by overall impression defeated infringement claim over "Liv.52" and "LIV-T".

Trade mark rights in "Liv.52" were upheld on the basis of valid registration, long use and market presence, but infringement was not proved against "LIV-T". Applying the anti-dissection rule, the Court held that the marks were not deceptively similar overall in visual, structural or phonetic impression, with no evidence of actual confusion and with product and distribution differences reducing mistake. The prefix "LIV" was treated as a generic, non-distinctive abbreviation for liver and could not be monopolised. As infringement failed, rendition of accounts also did not arise, and the suit failed.

Issues: (i) whether the plaintiff was the proprietor of the registered trade mark "Liv.52" for drugs and pharmaceuticals; (ii) whether the defendant's use of "LIV-T" amounted to infringement of the plaintiff's registered trade marks; (iii) whether the word "LIV" had become publici juris with the result that it could not be monopolised as a trade mark; and (iv) whether the plaintiff was entitled to rendition of accounts.

Issue (i): whether the plaintiff was the proprietor of the registered trade mark "Liv.52" for drugs and pharmaceuticals

Analysis: The plaintiff produced the registration certificate for the mark "Liv.52" and evidence of long, continuous and extensive use in relation to medicinal preparations. The registration remained valid and unchallenged. The evidence also showed substantial sales, advertising and market presence, supporting proprietary rights in the mark.

Conclusion: The issue was decided in favour of the plaintiff.

Issue (ii): whether the defendant's use of "LIV-T" amounted to infringement of the plaintiff's registered trade marks

Analysis: The marks had to be compared as a whole. Applying the anti-dissection rule, the Court found that the overall visual, structural and phonetic impressions of "Liv.52" and "LIV-T" were different. The Court also noted the absence of evidence of actual confusion over a long period of concurrent use, the distinct nature of the respective products, and the role of pharmacists and licensed outlets in reducing the risk of mistake.

Conclusion: The issue was decided against the plaintiff and in favour of the defendant.

Issue (iii): whether the word "LIV" had become publici juris with the result that it could not be monopolised as a trade mark

Analysis: The evidence showed that "LIV" was commonly used in the trade as an abbreviation for liver in relation to medicines for liver disorders. Numerous products in the market used the same prefix. The Court held that such a generic and non-distinctive component could not be monopolised and had to be given little weight in the comparison of marks.

Conclusion: The issue was decided in favour of the defendant and against the plaintiff.

Issue (iv): whether the plaintiff was entitled to rendition of accounts

Analysis: Once infringement was not established, the consequential relief of rendition of accounts did not arise.

Conclusion: The issue was decided against the plaintiff.

Final Conclusion: The suit failed because the defendant's mark was not found deceptively similar to the plaintiff's registered mark and no infringement was proved.
