Taiwanese companies are coming under further attack from the US for alleged infringement of trade regulations.
This time, US electronics vendor Oak Technology has complained to the International Trade Commission that a clutch of companies are importing components for CD-Roms, which allegedly breach its patents.
The companies targeted by Oak are United Microelectronics, Mediatek, the Lite On Group and Aopen. It complains that they have infringed a patent for technology that makes an adapter card unnecessary for CD-Roms.
But Oak is unlikely to get quick relief, as the ITU will probably take as much as a year to investigate the matter. If it rules in Oak's favour, the ITC has wide ranging powers to prevent imports.
Last year Oak took action against Winbond and UMC and gained a result in its favour, with the former licensing its technology. UMC, said the reports, also settled with Oak but that deal fell through after it complained products were still being sold through sister company Mediatek.
