Important amounts of investment are made in research and development to improve designs, techniques, and processes by SMEs to reduce production costs and increase sales. Trade secrets disputes often arise against employees or former employees and business partners and is a frequent issue affecting SMEs. However, in relation to Thailand, the Central Intellectual Property and International Trade Court (IP&IT Court), has published that only 66 trade secret cases were brought to the IP&IT Court between 2004 and 2014. Of this limited number of cases, the majority had unfortunately no positive outcome for trade secrets’ owners, with the main reason for the court to dismiss a plaintiff’s claim, being the absence of appropriate measures to maintain trade secrets. Key grounds to support a claim of trade secrets theft is indeed represented by the proofs of the existence of a trade secret by demonstrating that the information is protected by measures to maintain its secrecy. Failing to provide certain evidence in this respect, will lead to lose the case.
