Software copyright adopts a registration system, which is basically 100% passable. Patents are subject to review and must meet the conditions for patent authorization. The corresponding software is very difficult to authorize. A soft copy protects the external expression of the work, while a patent protects the function, performance, etc. of the technology. For the same software, the value of copyright is much less than the value of patents. The specific process of how to apply for a software patent is as follows: Software technology can apply for software copyright to protect the software source code, or it can apply for invention patents to protect the execution method of the steps in the software process. Patents protect the idea of ??software solving problems, while software copyright protects software code (that is, the expression of software ideas). For example, if you want to transfer files offline, then the invention patent protection is how to transfer files offline. Based on the same software idea, there are thousands of program codes that can be transmitted offline, and each code can enjoy its own software copyright. Applications for invention patents can be submitted directly to the Patent Office, or you can entrust an agency to do so.
