­Taiwan’s semi-official Industrial Technology Research Institute (ITRI) has sued South Korea’s LG Electronics, accusing it of infringing 22 of its US registered patents covering the fields of mobile phones, air conditioners, blue-ray discs, and LCD displays.

The Taiwanese company said that if the court does not block LG’s actions, then it “will suffer additional irreparable harm for which there is no adequate remedy at law and impairment of the value of its patent rights,” the ITRI claimed in its filing with the courts.

The case is similar to the IP litigation between Acer and HP three years ago, when the former successfully used the support of the ITRI to force the latter in accepting a settlement.

LG said in a statement it will take appropriate action when it receives the official court documents, which it expects later this month.

The ITRI is a technology developer that was founded in 1973 and is partly funded by the Taiwan government.
