Mediation between IndiGo Airlines and Mahindra Electric over the ‘6E/6e’ trademark has failed. The Delhi High Court will now take the case to trial in February 2026.
New Delhi: The mediation talks between InterGlobe Aviation Ltd (IndiGo Airlines) and Mahindra Electric Automobile Ltd have failed in their ongoing dispute over the use of the ‘6E/6e’ mark. The Delhi High Court was informed of this development on October 31.
Joint Registrar (Judicial) Sudhir Kumar Sirohi noted that the issue could not be settled through mediation. The Court has now directed both parties to file photocopies of all relevant documents and to prepare a joint schedule of documents. The matter will next come up on February 3, 2026, for admission, denial, and marking of exhibits.
The dispute began when IndiGo filed a trademark infringement suit before the Delhi High Court. The airline objected to Mahindra Electric using the name “BE 6e” for its new electric car, which was launched in February this year and gained significant attention on social media after its unveiling.
IndiGo has owned the registered word mark “6E Link” since 2015, under Classes 9, 16, 35, and 39. These classes cover items such as advertising and promotional materials, transportation-related services, illuminated signage, and printed advertising boards.
Despite this, the Registrar of Trademarks accepted Mahindra Electric’s application to register “BE 6e” under Class 12, which includes motor vehicles and related parts.
This prompted IndiGo to take legal action, claiming that Mahindra’s use of “6e” unlawfully took advantage of its “6E” mark.
The airline argued that “6E” is its distinctive identity and is used not only as a callsign but also across several services and products.
The case first came before Justice Amit Bansal, who later recused himself from hearing it. It was then taken up by Justice Mini Pushkarna earlier this year.
IndiGo, represented by Senior Advocate Sandeep Sethi, argued that the “6E” mark has built a strong connection with the airline due to nearly 20 years of continuous use since 2006.
The airline uses this brand for multiple services such as 6E Prime, 6E Flex, and 6E Add-ons, which include benefits like seat selection, priority check-in, extra baggage, pre-booked meals, and lounge access.
During the hearing, Sethi told the Court that Mahindra had reached out to IndiGo to discuss the matter. Later, Mahindra stated that it had changed its car’s name from “BE 6e” to “BE 6” and promised not to use “BE 6e” while the case was still pending. This statement was recorded by the Court.
After that, the Court sent the case to mediation. However, since the mediation did not succeed, the matter will now proceed to trial.
In addition to the High Court case, the opposition proceedings against Mahindra’s application for the ‘6e’ mark are also continuing before the Trademark Registry.
IndiGo is being represented by a team from Ira Law, while Mahindra Electric is represented by lawyers from Khaitan & Co.
