How many independent patents can there be?

As long as it is single, it can have any number of items. 10 I have seen many independent opinions. But more is absolutely possible, this is your right, of course, there must be oneness. Although the law stipulates that the number of claims should be reasonable, your application will not be rejected because of too many claims. However, with more independent rights, there will inevitably be more subordinate rights. If the claim exceeds 10, you have to pay an application surcharge, which cannot be reduced. Claim 10 or more, 150 yuan/item.
