Do you need specific product data to apply for a patent? Both are needed if necessary. Please give an example.

You need it, especially the characteristic data used to distinguish your product from other products, otherwise the patent office will protect you. Simple example: At present, the maximum size of TV is 50 inches. You built a 150 inch TV, and you can watch movies. Do we have to talk about this 150 inch TV? But the thickness of TV has nothing to do with watching big movies, not to mention. For another example, you invented a drug containing 5% caffeine and 95% chlorophyll, which can be used to treat insomnia. Of course, this ratio should also be provided.
