CMC Magnetics, Ritek, Prodisc Technology and Daxon Technology, the top four makers of CD-R discs in Taiwan, jointly filed a legal complaint with Taiwan's Fair Trade Commission (FTC) on June 5 against Philips for its Veeza CD-R patent licensing scheme. The top four makers of CD-R discs claim that Philip's new licensing program violates Taiwan's Fair Trade Law, Digitimes.com reports.

In response, Philips Taiwan indicated that it has not received notification from the FTC and therefore knows nothing about the complaint.

The joint complaint is aimed at forcing Philips to set reasonable CD-R patent licensing conditions.
