Can all patented products really be used? If the product obtains the national invention patent, will it have the same use effect as the introduction? Thank you very much

There are three kinds of patent applications: one is appearance patent, as the name implies, such as the outer packaging and packaging box of food, as long as it is original design and there is no conflict in advance, you can apply. The success rate of this kind of appearance patent application is 100%, and it is relatively easy to apply. There are also utility model patents, that is to say, for example, if you change a component of an electric car through your own research, you can improve or strengthen the speed of the electric car. In this case (although it is not an intergenerational change, but some changes have been made), it can be regarded as a utility model patent.

And the last invention patent you mentioned. This is the most difficult application. First, the patent office will conduct formal examination, and then it will conduct substantive examination, which will take a long time. Moreover, the restrictions on invention patents are very strict, and it is not easy to apply. Therefore, if an invention patent can be declared, its gold content is very large.

The patent number applied for is a patent number, but it is not necessarily an invention patent. This should be clear. For example, the package of a food says "national patent has been applied for, and the patent number is * * * * * * * *", which is the number of the appearance patent in this case.
