So you can make a trademark of whole grains, and relatively speaking, it is recommended that you register the trademark yourself, not through transfer, because the price of trademark transfer is definitely more expensive than that of your own registered trademark. And at present, the price of registered trademarks in China is relatively cheap.
At the same time, their registered trademarks can be used to build their own brands. Increasing the intangible assets of the company, if the transferred trademark has credibility problems, will directly affect the company's product sales.
