Not a lawyer, but I don't think it will affect these kinds of sites. The personal information collected in patents is collected due to government regulation. This is one of the lawful bases for using the data. The data is public information (as a result of that regulation). Affected people will have to be notified when creating a patent that their information will be used in that way -- something I think patent offices already do.

There are lots things that fall under that category, but I haven't really looked into it deeply because in my work we don't have any data collected due to government regulations.
