Apple, Siemens and technology licensor Sisvel together were reported as having forced an exhibitor to shut down an exhibitor's booth at CeBIT. The three had the unnamed e-reader and netbook maker's floor space cleared out on Friday after they alleged that the company violated patents. Lawyers for Apple, Siemens and Sisvel are said to have visited the company's booth on Thursday and levied a 10,000 euro ($13,626) fine in advance of a raid the following day by German police.
