Different intellectual property laws, which separately cover patent, trademark, and copyright, are intended to cover different types of creations. Theoretically, to ensure that society benefits from protected works, a single creation should only enjoy intellectual property (IP) protection under one law, rather than benefitting from concurrent protection under multiple laws. In Thailand, however, two Supreme Court judgments have held that one creation may enjoy concurrent protection under different IP laws. This article examines the implications of these decisions and provides advice on best practices for IP owners.
