Sterlite Technologies Wins Patent Litigation Against Fujikura LTD in Europe

The RealCase readMedium impact Positive

Sterlite Technologies Limited announced a favourable outcome in its patent litigation against Fujikura LTD. The European Patent Office revoked Fujikura's patent EP3796060, ending UK litigation. STL is now seeking recovery of legal costs from Fujikura.

Why it matters

Winning patent litigation can positively impact a company's market position and reduce potential liabilities, but the financial impact of cost recovery is not yet quantified.

The market read

The company has won a significant patent litigation case, leading to the revocation of the opposing party's patent and the potential recovery of legal costs.

Sterlite Technologies Limited (STL) has provided an update on its ongoing patent litigation. In a significant development, Fujikura's patent EP3796060, which was the subject of patent infringement litigation in the UK, has been revoked in its entirety by the Technical Board of Appeal of the European Patent Office, Germany.

This non-appealable decision effectively concludes the UK patent litigation concerning STL's Celesta cable family. Following this favourable outcome, Sterlite Technologies Limited is now actively pursuing the recovery of its legal defence costs from Fujikura.

The company had previously intimated about this litigation on December 5, 2025. This update is submitted pursuant to Regulation 30 read with Para B of Part A of Schedule III of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.
