There is no such thing as patent certification. If someone tells you this, they are 100% lying to you.
Food can be patented. The scope of patent application includes: the composition of the food, the dosage of each ingredient and the processing method of the food.
If a certain food has applied for a patent, it can only mean that the composition of the food and the dosage of each ingredient are unique; or that the processing method of this food is different from others and has its own production technology. During the patent protection period, other people cannot use the method recorded in the patent to produce the food without authorization.
However, this does not mean that food produced according to patented methods is necessarily better than others.
That’s all.
There may be organic certification, green certification, etc. in society to show that no pesticides have been used in the food, but patent certification is pure nonsense.
