Sterlite Technologies Wins European Patent Dispute Against Fujikura Ltd.
Sterlite Technologies (STL) won a European patent dispute against Fujikura Ltd. The EPO revoked Fujikura's patent on June 24, 2026. This ruling strengthens STL's position in Optical Connectivity markets in the UK and Europe and reaffirms its global IP defense capabilities.
Winning a patent dispute is positive for the company's reputation and market standing, particularly in its key European markets, but it does not immediately translate to a significant financial impact on its current operations.
The company has won a significant patent dispute, which is a positive outcome that strengthens its market position and validates its intellectual property.
Sterlite Technologies Limited (STL) has announced a decisive victory in its European patent dispute with Fujikura Ltd. The European Patent Office (EPO) Technical Board of Appeal, in a hearing on June 24, 2026, issued a final and non-appealable ruling revoking Fujikura's European Patent EP 3796060 in its entirety.
This ruling effectively resolves the UK patent dispute between the parties in STL's favor. STL's intellectual property (IP) portfolio, built over decades and protected by 785 patents across major global markets, has been strongly defended. This legal triumph is expected to strengthen STL's market position in Optical Connectivity across the UK and Europe, underscoring its global IP capabilities.
Dr. Badri Gomatam, Group CTO, STL, stated, “This ruling by the EPO's highest appellate body is a powerful affirmation of the strength of our global IP position, the integrity of our R&D and deep technology capability.” He further emphasized STL's vertically integrated 'Glass to Data Center' capability, ensuring quality control and supply chain resilience for its global customers.
