Can I continue to apply for a utility model patent after it has been rejected?

You can apply directly. Because the original rejection application is not made public, it does not belong to the existing technology and conflict application, so it will not affect the new application. There is no filing problem with the original application documents, and China National Intellectual Property Administration will handle and destroy them within a certain period of time. At the same time, when you file a new application, you can claim the priority of the original application.
