This does not have to be very detailed. A patent only needs to outline the key points of the entire technology. But you have to be clear about one thing. Patents are for publicity in exchange for protection. Generally speaking, you want your technology. To be protected, you must let the public know and make it public. Of course, you can also not write out the important technical points, but if you don’t write it out, it will not be protected. If someone later embezzles the technology that you have not written in, even if you apply for a patent, it will not be protected. Will not be protected. In addition, it may be that your patent lacks novelty or your application for inventive step is unsuccessful because you did not write down this technical point.
