Can I apply for a patent only if the scheme is not implemented?

How do you know that you can save construction costs if you haven't implemented it?

Of course, patents have patent rules, although in theory they should be effective, otherwise the above problems will arise. But in practice, it does not need to be implemented before applying for a patent.

It is recommended to consult a specific professional in person or by telephone.
