Mahindra BE 6New Delhi: Mediation efforts between InterGlobe Aviation, the operator of IndiGo Airlines, and Mahindra Electric Automobile have failed in the ongoing trademark dispute over the use of the ā6Eā mark, as per a report by The Economic Times.
According to a court Order dated October 31, Joint Registrar (Judicial) Sudhir Kumar Sirohi recorded that both parties informed the Delhi High Court that mediation could not resolve the matter. The Order also mentioned that hard copies or a joint schedule of documents have not yet been filed.
The court has directed both parties to submit photocopies of all admitted documents and prepare a joint schedule, besides asking them to inspect and flag their respective documents ahead of the next hearing. The defendant, Mahindra Electric, has also been granted liberty to file an additional affidavit of admission or denial if new documents are submitted with the replication.
The matter is next listed for hearing on February 3, 2026.
What led to this dispute?
The dispute originated from IndiGoās objection to Mahindra Electricās use of ā6Eā in its upcoming electric vehicle model, the BE 6e. IndiGo filed a lawsuit in December 2024, alleging trademark infringement and seeking relief from the courtās intellectual property division.
Mahindra Electric, a subsidiary of Mahindra & Mahindra, has maintained that its āBE 6eā trademark was filed under Class 12, which covers motor vehicles, distinguishing it from IndiGoās ā6Eā trademark registered for airline and related services. Mahindra Electric received trademark approval for āBE 6eā last year under Class 12, covering cars and commercial vehicles but excluding two-wheelers.
IndiGo uses ā6Eā as its callsign and key brand identifier across offerings such as 6E Prime, 6E Flex, and 6E Rewards, and has held registrations including ā6E Linkā under Class 35 since 2015 for advertising and airline services.
