Jason Wang, co-president of UMC, stated, "UMC is pleased with today's decision. UMC invests heavily in its intellectual property and aggressively pursues any company that infringes UMC's patents."

With today's ruling, Micron's products now face injunction for violating UMC's patent rights in a court verdict that applies to all of mainland China.

UMC has devoted a great deal of resources and manpower to researching and developing semiconductor manufacturing technology. Its achievements can be applied to logic chips or memory chips (DRAM), and the company has been awarded patents by various countries. UMC continuously monitors these patents as market conditions evolve. When violations occur, UMC stands ready pursue patent infringement litigation in order to obtain judgment and remedies to protect the intellectual property rights of the company.
