The battle between Siemens and LG Semicon was racked up a further notch yesterday when the German firm accused its Korean rival of infringing its Dram memory chip patents.
Reports said that Siemens sued LG Semicon over seven patents. The action was taken in a district court in Delaware and seeks an injunction against LG Semicon to prevent it making and selling the Drams concerned.
In early August, Siemens accused South Korean manufacturers of dumping products on the European market, forcing it to close its advanced Dram factory in the UK's Tyneside region. At the time, newly appointed DTI minister Peter Mandelson backed up the complaint.
But last week, the head of the Korean semiconductor association hit out at Siemens, denying all charges of dumping (see Newswire 24 August).
A representative for Siemens in Tyneside said she was unaware of the US legal action and did not know whether similar moves would be made in Europe.
