What is the difference between patent system and trade secret in technical protection?

First, the scope of protection is different. The object of patent can only be a complete technical scheme that can be applied in the industry. You can't apply for a patent for an unfinished technical scheme or a failed technical scheme, but these are trade secrets. Second, the essential elements of the two are different. The essence of patents is very demanding. As long as technical information is confidential, confidential and valuable, it needs to be protected by trade secrets, which is relatively lower than patents. Third, the cost of security is different. 1. Their economic costs are different. A patent is a right applied by all parties concerned and authorized by the state. The parties need to pay the patent application fee and the annual patent maintenance fee, while the trade secrets do not need to pay any fees to the state. 2. In terms of time cost, patent application takes a long time, but business secrets don't. 3. In terms of technology cost, the patentee must disclose his technology, which can be realized by technicians in his field, while the holder of trade secrets does not disclose his technology. Fourth, the protection is different. 1. Patent protection is a powerful protection. The patentee enjoys the exclusive right to manufacture, use, sell, promise to sell and import his invention-creation, regardless of whether others imitate or independently develop the same invention-creation; Trade secret is a kind of weak protection, and the obligee can only prohibit others from violating confidentiality obligations or obtaining, disclosing and using relevant trade secret information by other improper means. It is impossible to prohibit others from obtaining and using relevant secret information through legal channels. 2. When infringing on the right to trade secrets and patent rights, the obligee has different burden of proof, and to determine the scope of patent protection, the obligee needs to prove the trade secrets himself. 3. The term of protection of the two is different: the protection of patents has a term, while the right to trade secrets has no term. As long as the information still has the basic elements of trade secrets, it can be protected as trade secrets.
