1. You can't upload information that infringes the rights and interests of others, such as a newly published book. If scanned and uploaded to the library, it may affect the sales of new books, thus infringing on the rights and interests of others. If someone sues you in Baidu, your account may be blocked.
2. After uploading your original materials to the library, it means that you are willing to share them with everyone, but at this time you don't have the patent right. You need to declare a patent in the patent office before you can own it.
