The name of an invention patent is the name that conforms to the relevant provisions of the patent law and the technical field of the product involved in the invention. As long as the true meaning of the invention is accurately expressed, other modifiers irrelevant to the technical content are not allowed to be marked. Product name is a kind of commodity name, which can not only express the true meaning of the product, but also add non-technical modifiers related to the function and use of the product. Except for some special-purpose products that must conform to the corresponding naming rules (such as military products), most products can be named according to their functions, uses and even geographical features.
