Do patent attachments have to be detailed? Some secret links are too detailed, which may lead to easy imitation.

Needless to say, this is very detailed Patents only need to outline the whole technical point, but you have to be clear. Patents are protected. Generally speaking, if you want your technology to be protected, you must let the public know that it should be made public. Of course, you don't have to write down important technical points, but if you don't, you won't be protected. Later, someone will steal the technology you didn't write in, even if you apply for a patent. In addition, it is possible that your patent lacks novelty or your creative application is unsuccessful because you didn't write this technical point.
