Sterlite Technologies Wins Patent Dispute as EPO Revokes Fujikura's Patent

Sterlite Technologies has secured a definitive victory in its European patent dispute with Fujikura Ltd, following a final, binding, and non-appealable ruling by the European Patent Office (EPO) Technical Board of Appeal. The decision, issued on June 24, 2026, revokes Fujikura's European Patent EP 3796060 in its entirety, effectively resolving the UK patent litigation concerning the company's Celesta cable family in favour of Sterlite Technologies. This development removes a significant legal overhang and strengthens the company's intellectual property position across the UK and Europe.

The company disclosed this update pursuant to Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015. The ruling by the EPO's highest appellate body serves as a powerful affirmation of the strength of Sterlite Technologies' global IP position and its R&D capabilities.
