AI summary

Sterlite Technologies won a UK patent dispute against Fujikura. The European Patent Office Technical Board of Appeal revoked Fujikura patent EP3796060 in full in Sterlite's favour. This non-appealable ruling formally ends the UK patent litigation over Sterlite's Celesta cable family. The company is now pursuing recovery of legal defence costs from Fujikura.

Likely market impact

Positive for Sterlite as it removes a legal overhang on its Celesta cable products. Possible cost recovery from Fujikura adds further upside.
