By Foo Yun Chee BRUSSELS (Reuters) – EU regulators are poised to fine Philips, Samsung Electronics Co Ltd and Infineon Technologies AG in the coming weeks for fixing prices of chips used in mobile SIM cards, two people familiar with the case said on Tuesday. The case started with dawn raids on the companies by the European Commission in October 2008. Officials with the commission, Philips and Infineon declined to comment. Philips said last year that the EU charges covered the period 2003 to 2004 and involved its semiconductor business which it has since sold.
