Case Note & Summary

The dispute arose between Glaxo Group Limited and Shreya Life Sciences Pvt. Ltd. regarding the cancellation of Trade Mark Registration No. 5001470 for the mark 'LEFOXIN BIOX'. Glaxo, a UK-based pharmaceutical company, sought cancellation under Section 57 of the Trade Marks Act, 1999, claiming that the Impugned Mark was deceptively similar to its registered mark 'LANOXIN', which has been in use since 1956. Shreya, the registered proprietor of the Impugned Mark, contended that Glaxo was not a 'person aggrieved' and that the marks were not similar enough to cause confusion. The court analyzed whether Glaxo had a legitimate grievance and if the similarity between the marks could mislead consumers. It concluded that Glaxo's long-standing use of its mark and the phonetic and visual similarities between the two marks justified Glaxo's standing as a person aggrieved. The court emphasized that the likelihood of confusion must be assessed from the perspective of an average consumer and found that the addition of 'BIOX' did not sufficiently distinguish the Impugned Mark from Glaxo's mark. Consequently, the court ruled in favor of Glaxo, cancelling the registration of the Impugned Mark due to its deceptive similarity to the Glaxo Mark.

Nature of Litigation

Cancellation of Trade Mark Registration

Remedy Sought

Cancellation of Trade Mark Registration No. 5001470

Filing Reason

Claim of deceptive similarity to an earlier registered mark

Issues

Whether Glaxo is a 'person aggrieved' Whether the Impugned Mark is deceptively similar to the Glaxo Mark

Submissions/Arguments

Glaxo argued that the Impugned Mark is confusingly similar to its registered mark and poses a risk of consumer confusion. Shreya contended that Glaxo is not a person aggrieved and that the marks are sufficiently distinct.

Ratio Decidendi

The court held that a mark that is phonetically and visually similar to an earlier registered mark can create a likelihood of confusion, justifying cancellation under the Trade Marks Act, 1999.

Judgment Excerpts

Glaxo contends that it learnt of the Impugned Registration only in June 2024. The Impugned Mark is phonetically close to the long-standing and registered Glaxo Mark. The addition of BIOX appears to indicate that the Impugned Mark is a variant of the Glaxo Mark.

Procedural History

The petition was filed by Glaxo seeking cancellation of the Impugned Registration under Section 57 of the TM Act. The matter was heard with the consent of both parties, and extensive arguments were presented regarding the similarity of the marks and the standing of Glaxo as a person aggrieved.
