Verdes has patents in many countries. Of course the USA one only affects products in the USA. My 7x7 box (from Oct. 2008) says EP1599261 covers most of Europe, then there is HK1086212 for Hong Kong (i.e. where Meffert is), 23956 for Egypt, 2320390 for Russia, 116890 for Singapore, 2005/08909 for South Africa, 79699 for Ukraine...
Then the pending ones, 20004241790 for Australia, PI 0410204-5 for Brazil, 2522585 for Canada, 200480013109.3 for China, 2151/KOLNP/2005 for India, W-00200503110 for Indonesia, 171549 for Israel, 2006-530607 for Japan, 10-205-7021428 for Korea, PA/a/2005/011887 for Mexico, 20055913 for Norway, 1-2005-502042 for the Philippines, 10/555,013 for the USA.
My dad informs me that under international patent law, patents (even pending patents) illegalize the knockoffs at basically every stage. You can get someone for producing knockoffs, selling knockoffs, and even owning (!!!) knockoffs if they are doing it in a country you have a patent in. But basically - yes, it's illegal in China... but I wonder whether fighting it would be more expensive than being pirated in the first place.
