If there are three or four independent rights in a patent and one of them is invalidated, what will be the consequences? Is the patent invalid in its entirety or in part or is there any other solutio

Well, how should I put it? Each claim represents an independent scope of protection.

Other claims are still valid if they comply with the requirements of patent law. It's the same whether you have independent power or follow power.

If no claim is valid, all patents will be invalid. If it is still valid, it is partially invalid.
