How to apply for a patent when a design has multiple schemes?

1. Several schemes in a design can be submitted in a patent application if they have specific technical features that make creative contributions to the existing technology, that is, some patents that meet the requirements of oneness can be applied in one patent.

2. If several schemes in a design are not related to each other, you can apply separately, that is, each scheme applies for a patent. In this way, more effective protection can be obtained. Of course, if you are short of funds, you can also apply for several unrelated schemes in a patent, and apply separately if necessary.
