It mainly depends on what do you want to do now? First, if you want to have a patent certificate, then you can apply for a utility model patent. If yours is a method, then it is an invention patent. You said it is different from the original method. Based on the actual situation, I think you can still apply for a patent. , the unreasonable method itself is a patent, and the result does not necessarily need to be different to apply for a patent. The mobile phones used by everyone are not owned by the same company. Each company that produces mobile phones has its own patent. It can be said that there are mobile phones now, but it cannot be used anymore. Have you applied for a mobile phone patent? In addition, the Utility Model and Appearance Patent Department has undergone substantive examination, so if you want to have a patent certificate, you can still apply! If you want to attack others, don't say it's a result you've already achieved. Even if it's not something you've already achieved, and you haven't copied someone else's, it doesn't necessarily mean that your method hasn't been used in the world. Hope this helps!
