Counterfeit and imitation flood in developing countries such as the US and EU. These countries staged a world-wide campaign against counterfeit and fake.

At the end of 2006, the number of counterfeit seized by the US Department of Homeland Security (the DHS) increased by 83% compared to the previous year. In EU, customs confiscated about 75 million counterfeits in 2005 and cases related to counterfeit increased over 26,000 than the previous year.

The US and EU start international cooperation to protect intellectual property rights (IPRs) and take action together in the third country to fight against counterfeit and fake. On 2nd April, the United States Patent and Trademark Office (USPTO) and the General Department of Vietnam Customs held the 5-day-lasting seminar on Applying Risk Management in IPRs for Customs and Economic Police in Ho Chi Minh city, Vietnam.

Taking part in the seminar, representatives from General Affair Union of Customs and Tariff of EU members, the US Border Protection, the US Immigration and Customs Enforcement, and the USPTO shared their experience and professional knowledge with 60 customs officers and economic police of the South Vietnam.

According to USPTO, the tendency of globalization of making counterfeit and fake increasingly threatens trade and investment. Many current systems of providing counterfeit and fake of illegal organizations in the world have the sophisticated mode of operation. Besides traditional tricks like hiding counterfeit and fake in the second bottle of containers or mixing genuine and fake in a same lot, there are two new tricks including "desultory goods" and direct sales.

"Desultory goods" is the trick that hides the origin of goods by carrying to other territories, putting customs off the true origin of goods. Second trick is dispersing small counterfeits and fakes like imitation medicine by a new selling channel – Internet. So a number of counterfeits are directly sold to consumer without related authorities’ control.

USPTO also said the close cooperation among intellectual property rights enforcement offices is the effective method to protect consumers of Vietnam, the US, and EU from illegal and latently dangerous products that erode global society and economy.
