Fairchild Semiconductor Files Patent Lawsuit Against Power Integrations in China

According to Fairchild Semiconductor's news release, available here,

Fairchild is seeking a permanent injunction preventing the sale, manufacture or use in China, or the importation into China, of Power Integrations products alleged to infringe four Chinese patents, including products in the TinySwitch II, TinySwitch III, LinkSwitch II, LinkSwitch XT and TOPSwitch GX product families. The company is also seeking monetary damages. The lawsuit was filed in Suzhou Intermediate Court.

It is interesting to see that Fairchild is moving its IP battle with Power Integrations from the United States to China. Because Power Integrations has been winning cases against Fairchild and its subsidiaries, this move does not really come as a surprise. Nowadays, most IC chips are made in China anyway, so if Fairchild prevails in China, Power Integrations would lose business globally including the U.S. market.

We will follow this landmark China case. If the outcome is favorable to Fairchild, it could open a flood gate for other companies to try their luck in China. Because the Chinese judicial system is less transparent and less predictable, however, it remains to be seen how this case will turn out.
