Keywords:MagnaChip? Pixelplus? CMOS? patent infringement? photo diode?

MagnaChip Semiconductor filed three additional patent infringement claims against Pixelplus Co. Ltd. in the Seoul Central District Court as well as a separate appeal with the Intellectual Property (IP) Tribunal of the Korea IP Office (KIPO). The separate appeal was on one specific item out of a total of 13 separate items on the disputed photo diode patent, which, according to Pixelplus, was effectively cancelled and invalided by KIPO.

In September, Pixelplus announced that it obtained a positive and commendatory ruling from KIPO granting the company's request to effectively cancel and invalidate the disputed photo diode and sensor patents claimed by MagnaChip. Last October, Pixelplus announced that MagnaChip's claims on the photo diode and sensor patents were completely withdrawn from their complaint in the Seoul Court. MagnaChip, however, clarified that they are pursuing the lawsuit.
