TAIPEI, Taiwan The island’s largest IC design house, MediaTek Inc., has struck back at Sunnyvale-based Zoran Corp., in a war of words over ongoing patent infringement cases in the U.S. and China.
Last week, Zoran Corp. claimed victory in its ongoing dispute with MediaTek when the U.S. International Trade Commission (ITC) issued orders finding that Zoran's U.S. patent numbered 6,584,527 is valid and infringed by optical disk controller chips and chip sets sold by MediaTek.
The ITC also issued an exclusion order prohibiting MediaTek and certain MediaTek customers from importing into the U.S. any MediaTek optical disk controller chip or chip set and any storage system using those chips that infringe claim 3 of the patent.
In its response, MediaTek said the impact of the ITC ruling would be “minimal,” because it has already developed a “design-around solution.” MediaTek said it consulted with several patent attorneys about the new ICs, and is confident that they do not infringe on Zoran’s IP.
"MediaTek has already provided its customers with the new-generation chip sets and all customers have already migrated to the new solution in their products since the middle of this year,” the company said in a statement.
However, Zoran said it, too, is confident that MediaTek's newest generation of chips and any systems that use them will be banned from the U.S. market.
MediaTek said it will be appeal the latest decision, and continue its counterclaims in the U.S. and in China. It expects rulings soon.
