Utility model refers to a new technical scheme suitable for practical use for the shape, structure or combination of products.
The protection period of the utility model is short, which is limited to the technical scheme of the shape and structure of the product (such as a detachable bicycle).
The invention has a long protection period, which can not only protect the contents of the utility model, but also protect some method inventions, such as a network communication method!
Their protection efficiency is almost the same (if they are all novelty or creativity), but the degree of review is different (the invention intellectual property office will review novelty and creativity before authorization, and it is not easy to be invalid after authorization, and the utility model will be invalid after authorization). I hope I can help you adopt it.
