If the safe you are talking about is in physical form, it is not safe. Because when applying for a patent, except for confidential patents, the contents of other patents will be made public, so plagiarism can be seen on the patent website.
If the safe you are talking about is intangible and refers to laws and regulations on intellectual property protection, then it is not necessarily safe. Because the reason why there are laws is because there are so many infringements, so legal protection is needed. However, the effect of legal protection in our country is limited, which is why foreigners have always cited the disadvantages of intellectual property protection.
The truly safe patent means continuous innovation. Don’t expect to sleep on the patent certificate.
