The following is excerpted from a November 30, 2007 press release available at PR Newswire:
Pixelplus Co., Ltd. (Nasdaq: PXPL), a fabless semiconductor company in Korea that designs, develops, and markets CMOS image sensors for various consumer electronics applications, today announced that the claims on the disputed contact hole process patent asserted by MagnaChip Semiconductor ("MagnaChip") have been completely withdrawn from MagnaChip in Seoul High Court. Given this favorable development, MagnaChip's patent infringement claims on the contact hole process patent will no longer be contested or remain at issue.
In February 2007, the Company announced it obtained a completely positive and affirmative ruling in the patent infringement proceedings from the Seoul Central District Court on the disputed color filter and contact hole process patents claimed by MagnaChip. In March 2007, MagnaChip filed an appeal with the Seoul High Court to reverse this earlier ruling issued by the Seoul Central District Court.
