Is it difficult to apply for a patent?

Declaring on the basis of the original invention depends on whether your core content conflicts with the original patent. If the patent creator belongs to you, it is not a problem. If not, the opinions of the patent examination department are needed. Whether it can be awarded to you depends on their answers. The procedure of applying for a patent is not complicated. You can see the application steps on the website of the Intellectual Property Office. The difficulty is directly related to the type of patent you apply for. Generally speaking, invention patents are more difficult and more demanding than utility models and appearance patents. I hope my answer is helpful to you. Thank you.
