What is the difference between technical secrets and patent protection in terms of protection methods?

The protection method of technical secrets is to take a hidden way, which is only known to a certain range of people and controlled within the necessary minimum range. The principle of patent disclosure is a way of disclosure and protection. When applying for a patent, the inventor must explain the content and technology of the invention to the patent department, which will issue a patent certificate and publish all its technologies in the patent bulletin. The patentee is protected by the patent law. Without the permission of the patentee, the patentee may not transfer, use or copy at will. The patent law stipulates that the patentee is allowed to indicate the patent sample and patent number on the packaging of his patented product, so that the public knows that the patented technology will not be infringed.
