Original Equipment Manufacturing or OEM is the business model that is used when a trademark owner is "sourcing", i.e., looking for a factory to manufacture its products, using its trademark. China is one of the most favoured countries by business operators sourcing OEM products. If you are one of them and want to ensure the safe exportation of the OEM products, is there anything you need to do? And if, assuming you do not own a registration of the trademark in China, you want to prevent others from registering such trademark, can you rely on your prior OEM export business?
