Trade Secrets Act provides a framework for effective protection of trade secrets. According to Art. 1 of the law, trade secrets are referred to as any method, technology, process, formula, program, design, or other information that may be applied in the course of production, sales, or business operations. The information shall be protected if and only if it is commercially valuable because of its secrecy and reasonable confidentiality measures have been taken to keep it secret. In addition, according to Art. 15, the protection of trade secrets of foreign nationals is based on the principle of reciprocity. In principle, if a foreign national's home country does not deny protection to the trade secrets of Taiwan nationals, and the foreign national's trade secrets meet the requirements of Taiwan's Trade Secret Act, the foreign national will enjoy the protection of such trade secrets under Taiwan's Trade Secret Act.
