AI summary

Sterlite Technologies shared an update on the UK patent case filed by Fujikura Ltd and Fujikura Europe in November 2023, alleging that STL's ribbed cables infringed patent EP 3 796 060 B1. The UK High Court issued a split judgment: STL's ultra-high-fibre-count cables do not infringe, but low-fibre-count cables were held to be infringing. Financial impact is not yet ascertainable. STL plans to file an appeal against the ruling on low-fibre-count cables.

Likely market impact

Partial loss in UK patent case; appeal planned. Financial impact not quantifiable yet; may affect UK low-fibre cable business.
