Registered trade mark conclusiveness after seven years defeats challenge for lack of original distinctiveness absent fraud or deception.

After seven years, a Part A registered trade mark becomes conclusive as to validity, and it cannot be impeached merely for want of original distinctiveness. Section 11 was treated as addressing prohibitory grounds such as deception, confusion, or inherent disentitlement, not a bare failure to meet the initial requirements of registration. On the evidence, there was no fraud, no substantial proof that the marks had become deceptive or confusing, and no adequate material to show that they had ceased to distinguish the proprietor's goods. Sporadic third-party use was insufficient to prove that the marks had become publici juris or abandoned, so cancellation was refused under sections 11, 32 and 56.

Issues: Whether the registered trade marks consisting of the numeral "50" and the word "Fifty" were liable to cancellation on the grounds that they were not distinctive, had become common to the trade, or were otherwise hit by the prohibitions in section 11 of the Trade and Merchandise Marks Act, 1958, so as to defeat the conclusiveness attached to registration under section 32.

Analysis: Registration under section 31 is prima facie evidence of validity, and after seven years section 32 makes the original registration conclusive except on the limited grounds stated therein. The challenge based on initial lack of distinctiveness could not succeed merely because the marks might not have been shown to satisfy section 9 at the time of registration. Section 11 was held to deal with prohibitory matters such as likelihood of deception or confusion, or some inherent disentitlement to protection, and not with mere absence of the requisites of registration. On the evidence, there was no fraud, no substantial proof that the marks had become deceptive or confusing, and no sufficient material to show that the marks had ceased to distinguish the respondent's goods at the commencement of the proceedings. Sporadic or few infringements by others did not establish that the marks had become publici juris or abandoned.

Conclusion: The trade marks were not liable to cancellation under sections 11, 32 or 56, and the challenge failed.

Ratio Decidendi: After seven years, a registered trade mark in Part A cannot be impeached for want of original distinctiveness; it can be displaced only on the limited statutory grounds, and non-substantial third-party use will not by itself destroy distinctiveness.
