Dishonest adoption of a well-known mark and its abbreviation precludes the defense of honest concurrent user.

The Petitioner, a global real estate franchising multinational incorporated in 1971, sought the rectification and removal of four trademarks (‘C21’ device marks) registered by Respondent No. 1 in 2010 across Classes 16, 35, 36, and 41.

The Petitioner asserted prior statutory and common law rights in the marks "CENTURY 21" and "C21" globally (since 1971) and in India (registrations dating back to 1989).

Respondent No. 1, incorporated in 2006, adopted "Century 21" into its corporate name and claimed user of the "C21" marks from 2007.

The Petitioner alleged that the Respondent’s adoption was dishonest and intended to capitalize on the Petitioner’s international reputation and trans-border goodwill.

1. Whether Respondent No. 1 is the prior user of the impugned marks in India under Sections 33 and 34 of the Trade Marks Act.

2. Whether the Petitioner established sufficient trans-border reputation and spill-over goodwill in India to invalidate the Respondent’s registrations.

3. Whether the adoption of the impugned marks by Respondent No. 1 was honest and bona fide.

The court applied Section 2(2)(c) of the Trade Marks Act, 1999, which defines the "use of a mark" in relation to services as a reference to their availability or performance.

It relied on the principle from *N.R. Dongre v. Whirlpool Corporation* and *Milmet Oftho Industries v. Allergan Inc.*, establishing that a prior global user with trans-border reputation in India is entitled to protection against a subsequent local adopter.

The court further applied the doctrine from *Satyam Infoway Ltd. v. Siffynet Solutions Pvt. Ltd.*, holding that domain names function as business identifiers and constitute valid trademark use.

Finally, it followed the principle that "dishonest adoption" cannot be cured by subsequent long-standing use, as established in *MAC Personal Care Pvt. Ltd. v. Laverana GMBH*.

The court found Respondent No. 1’s claim of prior user from 2007 to be "plainly untenable," as its earliest documentary evidence (invoices/advertisements) only dated back to 2010.

Conversely, the Petitioner proved "CENTURY 21" was registered in India as early as 1989 and demonstrated active Indian market engagement via domain registrations (2006) and franchise agreements (2007).

The court rejected the Respondent’s "territoriality" defense, noting that the Petitioner’s reach through digital media and global study rankings constituted "spill-over goodwill."

Crucially, the court held the Respondent’s adoption was "dishonest by design" because it not only copied the "C21" mark but also subsumed the Petitioner's entire brand name into its corporate title while operating in the same industry.

Technical objections regarding the stamping of franchise agreements were dismissed, as the proceedings concerned in rem rectification rights rather than private contractual disputes.

The court ordered the removal of Trade Mark Registration Nos. 1941724, 1941725, 1959526, and 1957532 from the Register of Trade Marks.

The petitions were allowed with no order as to costs.
