Trade mark registration relation-back and deceptive similarity are assessed by overall impression and likelihood of confusion.

Registration of a trade mark can support an infringement action even if the suit was filed before the registration certificate issued, because registration relates back to the application date under the Trade and Merchandise Marks Act, 1958. The text also explains that deceptively similar marks are assessed by their overall impression and essential features, viewed from the standpoint of an average purchaser with imperfect recollection. Actual deception is unnecessary where likelihood of confusion is shown, and similarity in device, trade name and visual impression may be sufficient to establish infringement and passing off.

Issues: (i) Whether the suit for infringement was maintainable where the trade mark was registered after institution but with effect from the date of application; (ii) Whether the defendant's mark was deceptively similar to the plaintiff's mark so as to amount to infringement and passing off.

Issue (i): Whether the suit for infringement was maintainable where the trade mark was registered after institution but with effect from the date of application.

Analysis: Under Section 23 of the Trade and Merchandise Marks Act, 1958, registration takes effect from the date of application and is deemed to be the date of registration. On that basis, the later certificate related back to the application date, so the plaintiff was entitled to maintain the action notwithstanding that the plaint had been filed before the certificate was issued.

Conclusion: The suit was maintainable and the objection to jurisdiction failed.

Issue (ii): Whether the defendant's mark was deceptively similar to the plaintiff's mark so as to amount to infringement and passing off.

Analysis: For infringement under Section 29 of the Trade and Merchandise Marks Act, 1958, the essential features of the registered mark must be considered, and the comparison must be made from the standpoint of an average purchaser with imperfect recollection. Under Section 2(d), a mark is deceptively similar if it is likely to deceive or cause confusion. The marks in question had an overall resemblance in the fish device, the trade name, and the visual impression likely to be carried to illiterate or ordinary beedi , even though there were differences in details. Actual deception was unnecessary once likelihood of confusion was shown.

Conclusion: The defendant's mark was deceptively similar and the plaintiff succeeded on infringement and passing off.

Final Conclusion: The decree of the trial court was set aside, and the plaintiff obtained declaratory and injunctive relief, while the claim for damages failed for want of proof.

Ratio Decidendi: In determining deceptive similarity, the court must assess the overall impression and essential features of the marks from the viewpoint of an average purchaser with imperfect recollection, and registration relating back to the application date can validate a suit for infringement even if the certificate issues later.
