What's the difference between software copyright and invention patent?

One more thing: If you design the technical content of an application for an invention patent in the software copyright registration, you must apply for an invention patent first, and then register the software copyright, because the invention patent is subject to novelty examination, otherwise it will have an impact.

To avoid the above situation, we must ensure that the patent application date is before the software copyright registration date, even if it is one day.
