The main difference between OEM and ODM is that the former is the product design scheme proposed by the entrusting party - no matter who completes the overall design - and the entrusting party shall not provide the third party with the product adopting the design; the latter is completed by the manufacturer from design to production, and purchased by the OEM after the product is formed. Whether the manufacturer can produce the same product for a third party depends on whether the OEM buys the design. OEM products are customized for brand manufacturers.
After production, only the brand name can be used, not the name of the manufacturer. ODM depends on whether the brand enterprise has bought out the copyright of the product. If not, the manufacturer has the right to organize its own production, as long as there is no design identification of the enterprise. To put it bluntly, the difference between OEM and OEM lies in who owns the intellectual property right of the product. If the client owns the intellectual property right of the product, it is OEM, also known as "OEM"; if it is the overall design of the manufacturer, it is ODM, commonly known as "OEM".
