Trade secrets are "unknown to the public", that is, as long as they are not common information well known in the industry, information that can maintain the lowest secrecy or novelty difference from common information constitutes trade secrets.
The difference between trade secrets and patent rights lies in that the patentee must not have published the same technical invention and utility model in domestic and foreign publications when applying for a patent; However, trade secrets do not exclude the obligee, which is absolutely unknown at home and abroad, but has not been made public or well known in the industry. The fact that a trade secret is "unknown to the public" also shows that it can fully realize its commercial value and become the trade secret of the obligee.
