Ramji Lal Agarwal v.Sourav Agarwal

Calcutta High Court · P66149235

This appeal before the Calcutta High Court addressed whether a dispute arising from a family arrangement, involving the use of the trade name 'Sindharam Sanwarmal', constituted a 'Commercial Dispute'. The plaintiff argued that the matter was purely familial and not commercial. However, the court found that the reliefs sought—specifically perpetual injunctions restraining the defendant from using or permitting others to use the trademark—manifestly demonstrated an intellectual property dispute. Consequently, the High Court held that the suit must be triable exclusively by a Commercial Court under the Act of 2015.

Ramji Lal Agarwal v.Sourav Agarwal

Calcutta High Court · P69200140

This appeal before the Calcutta High Court addressed whether a dispute concerning the use of the trade name 'Sindharam Sanwarmal' fell under the ambit of 'Commercial Disputes' as defined by the Commercial Courts Act, 2015. The plaintiff argued that the matter arose from a family arrangement and was not commercial in nature. However, the court found that the reliefs sought, specifically perpetual injunctions restraining the use of the trade name, manifestly demonstrated an intellectual property dispute relating to trademarks. Consequently, the suit was held to be triable exclusively by a Commercial Court.

Ramji Lal Agarwal v.Sourav Agarwal

Calcutta High Court · 14721494

This appeal before the Calcutta High Court addressed whether a dispute over the use of the trade name 'Sindharam Sanwarmal' could be heard in a regular civil court or required a Commercial Court. The core issue revolved around classifying the conflict, which arose from a family arrangement concerning business goodwill, as a commercial dispute under the Commercial Courts Act, 2015. The court ultimately held that since the reliefs sought involved perpetual injunctions restraining the use of the trade name, the matter squarely fell within the purview of intellectual property rights and thus constituted a Commercial Suit.

PepsiCo, Inc. v.Jagdamba Foods Pvt. Ltd. And Anr.

Calcutta High Court · 40928056

PepsiCo successfully petitioned the Calcutta High Court for the cancellation of a similar trademark, 'JAY'S,' registered by Jagdamba Foods Pvt. Ltd. The court found that the impugned mark was phonetically identical and deceptively similar to PepsiCo's well-established brand, 'LAY'S.' Given the similarity in goods (snack foods) and the petitioner's immense goodwill, the court ruled that the registration of 'JAY'S' violated the Trademarks Act and must be cancelled.

M/S. Polo / Lauren Company, L.P. v.M/S. Loren Beautifiers Pvt. Ltd. And Anr.

Calcutta High Court · 100970902

The Calcutta High Court allowed an application for rectification filed by M/S. Polo / Lauren Company against a similar trademark, 'LOREN'. The petitioner argued that the respondent's mark was registered dishonestly and created a likelihood of confusion with their established global brand, 'RALPH LAUREN'. Crucially, the court noted that the impugned registration had long lapsed and no steps were taken by the respondent to renew it. Consequently, the court directed the removal and expunging of the expired trademark entry.

Calcutta High Court · 17233493

Pankaj Plastic Industries Private Limited filed a suit alleging trademark infringement and passing off against Anita Anu regarding the use of 'Poly Punkaj' for plastic goods. The core dispute revolved around whether the court should dispense with mandatory pre-suit mediation under Section 12A of the Commercial Courts Act, 2015. Although the plaintiff claimed urgency due to the defendant's alleged bad faith registration, the High Court ultimately dismissed the appeal. The judgment held that the plaintiff's prolonged delay in approaching the court demonstrated a lack of genuine urgency, leading to the revocation of leave and dismissal of the suit on procedural grounds.

Calcutta High Court · 77504901

Marriott Worldwide Corporation v.Sunjoy Hans And Ors.

Calcutta High Court · 182894016

Marriott Worldwide Corporation successfully appealed a decision by the Deputy Registrar of Trademarks that had dismissed its opposition against a deceptively similar mark. The Calcutta High Court found that the rejection was based purely on technical procedural grounds—specifically, the lack of apostille on evidence filed in the US—and not on the merits of the case. The court ruled that statutory provisions and rules governing trademarks supersede general laws like the Notaries Act, allowing for notarized affidavits from abroad to be accepted. Consequently, the original order was set aside, and the matter was remanded back for a fresh hearing.
