The Royal Style and Title Patent

The process of obtaining a patent for the floating aerator (Chaipattana Aerator) in the Royal Style and Title, and in accordance with the 1979 Patent Act is as follows:

- 2 June 1992: The Chaipattana Foundation submitted document number 016185 to the Department of Intellectual Property for the preliminary inspection and paid the required fee of Baht 1,000.

- 1 August 1992: The Invention Patent Document was advertised by the Department of Intellectual Property with the fee to be paid set at Baht 500; were able to be loaded within 180 days (1 August 1992 - 1 January 1993) objections to the patent (based on infringement rights, models, etc.)

The Inspection of the Invention
These were the steps in the process of inspection:
The aerator patent was inspected by the Australian Patent Office to which the Department of Intellectual Property sent the invention. It was found that there were eight related registered patents: five American owned patents; one French patent and two Australian patents. Only one of the Australian patents showed similarities.

The matters under consideration were as follows:

1. Considerations as a New Model

1.1. The primary water turbine had a rectangular cutting area but the present turbine has a trapezoid cutting area with holes drilled on both sides and with six opening turbine in total.

1.2. The water turbine had twelve sides but the earlier shape is circular.

2. Consideration of Enhanced Techniques:
The water turbine frame has been changed from a circular one to one with twelve sides; the rectangular to a trapezoid turbine. This new turbine has a better air filtering effect and moves more water in the operation. Therefore, these enhanced techniques are worth considering.

3. Consideration of the Adaptation to Industrial, Commercial, Agricultural and Handicraft Use:
The invention can be used in industry to eliminate polluted water in the communal, industrial and agricultural sectors to provide more oxygen and purify the water for the increase of marine life animals which are useful for agriculturists.
