(1) Obtaining the business secrets of the obligee by theft, inducement, coercion or other improper means;

(2) disclosing, using or allowing others to use the means mentioned in the preceding paragraph to obtain the business secrets of the obligee;

(3) disclosing, using or allowing others to use the business secrets in their possession in violation of the agreement or the requirements of the obligee to keep the business secrets. If a third party knows or should know the illegal acts listed in the preceding paragraph and obtains, uses or discloses other people's business secrets, it shall be regarded as infringement of business secrets. The term "business secrets" as mentioned in this article refers to technical information and business information that are not known to the public, can bring economic benefits to the obligee, are practical and are kept confidential by the obligee.
