Interesting story in the LA Times about a trademark dispute in China involoving In-N-Out Burger - who doesn't even have any stores in China - or outside the US at all for that matter.

They tracked down the owners of the copycat business in California and brought suit to prevent use of their intellectual property. The matter settled quickly. Moral: policing valuable trademarks around the world is important, and there are always creative solutions.
