Adani Group Faces US Patent Infringement Lawsuit by First Solar
First Solar, a big US solar panel company, says Adani's company in India copied their special way of making solar cells.
They sued Adani in court, claiming they stole their ideas.
Adani says they didn't copy anything and their method is different.
The fight is about a type of solar cell technology called TOPCon.
First Solar makes money by selling solar panels and might lose sales if Adani wins.
Adani sells a lot of solar panels to the US, and this lawsuit could hurt their business.
Both companies will have a jury decide who is right.
First Solar accused Adani Group's Mundra Solar PV Ltd of infringing on solar panel manufacturing patents in the US.
First Solar filed a lawsuit in Delaware court, seeking compensation, while Adani's MSPVL denies the claims.
The dispute involves TOPCon, a solar cell technology, with First Solar alleging patent violation and Adani claiming differences in manufacturing.
MSPVL, a key Adani unit, has significant revenue from the US, benefiting from tariffs on Chinese solar cells.
Both companies have demanded a jury trial, with implications for Adani's US solar panel exports and First Solar's market position.
