1. For software systems, patents can protect the idea of ??the software, while copyright can protect the expression form of the software (for example, the interface and code of the software are protected by copyright).
2. Software ideas that can be patented are conditional: only new technologies that adopt technical means, solve technical problems, and achieve technical effects can obtain patent protection. Therefore, you can make your own comparison and analysis as to whether the "idea of ??an IT system, or the design, planning, and scheme of the system" you mentioned meets the conditions for patent protection.
3. A patent application must be filed first, and then the software ideas can be organized into project introduction materials for external dissemination.
