The European Commission is expected to launch an investigation into patent protection for CD-Rs in Taiwan. The Commission investigation will be initiated under the EU's rarely used Trade Barriers Regulation. The investigation follows a complaint filed by Philips, after the Taiwanese authorities granted a compulsory licence to a small CD-R producer, Giga Storage, to produce and sell CD-Rs using patents held by Philips. Philips claims the compulsory order legalises the use of patents that Giga Storage was already infringing, and alleges that products manufactured under the compulsory licence are being exported in breach of the TRIPs Agreement (Trade Related Aspects of Intellectual Property Rights).
