What's the difference between having your own name under the utility model patent?

First, you need to know a premise. All utility model patents can be declared as inventions, and vice versa. Then you will ask why others declare utility models instead of inventions? Isn't invention more valuable than utility model? Because the technical method of the first invention patent needs to be announced, it is to let everyone know that this technology was invented by me, and in this way, it plays a protective role. Then some enterprises can't publish methods, but they want to protect them, so they can only choose utility models. The second application is simple, low cost and low annual fee. Ok, let me talk about the difference between invention and utility model. The so-called invention patent can be a technology, a method or even an idea. For example, a formula of western medicine, then this can apply for an invention patent. The so-called utility model patent refers to a structure. Therefore, when writing the technical disclosure, the utility model will usually be accompanied by drawings, such as the design of a machine, or even partial modifications. Just like you said, the mouse has evolved from a mechanical mouse to an optical mouse. Because of the change of sensor, optical mouse can be defined as a utility model patent, but at the same time, it can also declare an invention patent. The above thugs are purely professional.
