The Copyright Act 1994, which is Thailand’s current law, came into force on 21 March 1995. It was adopted during a period of intense external pressure demanding a complete overhaul of the country’s intellectual property laws. The Trans-Pacific Partnership (TPP) provisions provide that all TPP partners must envisage the very dynamic digital agenda of the World Intellectual Property Organization. The development of intellectual property law has become the subject of growing concern amongst citizen groups, environmentalists, academics, and the general public in developing countries. They believe that a higher level of patent protection and enforcement will increase the public burden. National law and practices on the patenting of second and further medical uses of known products vary from one country to another. The law of most nations requires pharmaceutical and agrochemical products to be registered with the competent authority before they can be put on the market.
