According to China's patent law. To apply for a patent, an invention must have three characteristics. Practicality, creativity and novelty. The so-called practicality means that the dish you invented must be used in life, and it is a good dish that people can love to eat. At the same time, when examining a patent, you must be able to show the work again, not a product that can only be manufactured once and needs to be manufactured repeatedly.
The so-called creativity means that your dishes have their own outstanding food characteristics and techniques compared with all the dishes you have created before. No matter from the selection of materials, cooking methods, ingredients, we must be unique and different from the past. Otherwise, this dish is not creative and can't be patented. Finally, the so-called novelty means that the dish you want to apply for has never appeared or been published in the past, and no other inventors have applied for patents and products similar to yours.
At the same time, if someone uses your food in front of the public without permission after your patent application is successful, according to Article 2 of the Copyright Law, others may not copy it without the permission of the copyright owner, or they will be punished by law. If you put this dish you invented on the market, it will certainly attract many customers, which is a great business opportunity, because many people are particularly pursuing those so-called signature dishes now, which will attract diners from all directions.
