If you apply for a patent and the technical information has been disclosed, it is no longer a trade secret. A trade secret is one that is not known to the public, can bring economic benefits to the right holder, is practical and has been approved by the rights. technical information and business information that have been kept confidential. If the patent application is protected, the right holder has patent rights. Patent rights are exclusive, so reverse engineering cannot be carried out. If it is a trade secret, reverse engineering can be carried out as long as the item is obtained legally, because trade secrets have no exclusivity.
