Shares in US chipmakers fell on Tuesday after Taiwan’s United Microelectronics Corporation said a Chinese court had issued an order blocking the sale of some products made by rival Micron Technology.
Micron shares were down 6.3 per cent following the announcement from UMC. The Taiwanese group had filed patent infringement lawsuits against Micron subsidiaries in Chinese courts earlier this year, relating to several products including some solid-state hard drives and memory sticks.
“With today’s ruling, Micron’s products now face injunction for violating UMC’s patent rights in a court verdict that applies to all of mainland China,” UMC said on Tuesday.
