Patent
It is an overwhelming joy for all Thais upon learning that the Chaipattana Aerator has been considered and received a patent in His Majesty the King’s name on February 2, 1993. The aerator is the world’s ninth mechanical aeration device to be patented and the first to be registered as well issued a patent to a Monarch. This patent signifies His Majesty the King as “the first Monarch in the Thai and world history to receive a patent.”
