Can app apply for a patent?

You can apply for invention by sorting out the technologies involved in APP into the method steps in the process of data processing and interaction. APP itself is software, and it cannot protect the product itself through patents like equipment or mechanical devices with actual shapes and structures. APP can't apply for utility model, and the UI interface of app can't be protected by design before. Now that the policy has changed, it may be possible in the future. It is entirely possible before the APP is made. Patents, even product inventions, don't need actual products, just ideas. On the contrary, if you make a product and apply again, you may not be able to apply, which will affect its novelty and will not be authorized. Patent application, as soon as possible, not too late, the application date is very important. If you want to apply, keep the technical documents confidential, and don't accidentally reveal the content to be protected online. Just ask questions like you, just say app, not what it is.
