The Delhi High Court has extended an interim injunction over the “THUNDER 15000” beer trademark to cover Delhi-based importer and distributor Supar SIP Traders LLP, after the firm admitted to importing and distributing the product under a contractual arrangement with the original defendant.

Justice Tejas Karia, presiding over the suit filed by Inbrew Beverages, added Supar SIP Traders as a party and directed it to be bound by the injunction granted on August 11, 2026, against Kinjore Brewery Private Limited and another defendant. The order marks a significant step in enforcing trademark rights against downstream supply-chain entities that handle infringing goods.

Importer Admitted Contractual Arrangement

Inbrew Beverages initially sued Kinjore Brewery and another entity over the use of the “THUNDER 15000” mark, securing an interim injunction from the court on August 11, 2026. Shortly afterward, Inbrew discovered that Supar SIP Traders had obtained an excise licence from the Delhi Excise Department on April 16, 2026, and was actively importing and distributing beer under the same mark within the capital.

Inbrew moved to implead the firm, amend its plaint, and extend the injunction. Supar SIP Traders opposed the application, arguing in its reply that it was “merely an importer and distributor of the product bearing the impugned mark 'THUNDER 15000' within the territory of Delhi, acting under a contractual arrangement with Defendant No. 1.” It maintained that its role was “purely that of a downstream entity in the supply chain” and that any injunction or decree against the principal defendants would automatically bind distributors, making its presence in the suit “wholly superfluous and redundant.”

Inbrew countered that this very admission—acknowledging a contractual link and active distribution of the allegedly infringing product—made Supar SIP a necessary and proper party.

Justice Karia agreed. The court observed that it was “apparent that proposed Defendant No.3 is involved in importing and distributing the product bearing the impugned mark 'THUNDER 15000' within the territory of Delhi,” and accordingly held that the firm was “a necessary and proper party to the Suit.”

Prima Facie Case and Balance of Convenience

On the question of extending the injunction, the court noted that Supar SIP Traders “has admitted that Defendant No.3 is an importer and distributor of the product bearing impugned mark 'THUNDER 15000' within the territory of Delhi and has contractual arrangement with Defendant No.1.”

Based on this admission and the evidence on record, Justice Karia found that Inbrew had made out a prima facie case. The balance of convenience also tilted in favour of the plaintiff, as the court concluded that Inbrew would “likely suffer irreparable loss” if the injunction were not extended to the newly added defendant.

The court therefore directed Supar SIP Traders to be bound by the August 11, 2026 interim injunction, effectively barring it from importing, distributing, selling, or otherwise dealing in beer bearing the “THUNDER 15000” mark.

What Happens Next

Supar SIP Traders, which accepted summons and notice during the proceedings, must now file its written statement within 30 days. The statement must be accompanied by an affidavit admitting or denying the documents relied upon by Inbrew Beverages.

The suit is scheduled to come before the Joint Registrar on December 11, 2026, and before the court for further hearing on December 21, 2026.

Legal practitioners and intellectual property observers will be watching the case closely, as it clarifies the extent to which trademark owners can hold downstream distributors and importers liable for infringement, even when those entities argue they are merely passive links in a supply chain. The ruling underscores that a contractual arrangement with a primary infringer can make a distributor a necessary party, and that an interim injunction may be extended to such entities without separate infringement proceedings.

For Inbrew Beverages, the extension provides immediate relief by plugging a potential loophole through which infringing products could continue to reach consumers in Delhi. For Supar SIP Traders, the order means it must immediately cease handling the disputed product or risk contempt proceedings.

The case also highlights the importance of due diligence for importers and distributors. Even a downstream entity that does not manufacture or brand the product can be directly affected by trademark litigation if it admits to a contractual relationship with the alleged infringer.
