IPR related Thai legal structures
Thailand has amended its Patent Act to conform with the main points of TRIPs since 1992, eight years before the 2000 deadline in WTO agreement
Thai Patent Act and Trade Secret Act conform with all TRIPs’ requirements
However, the Patent Act still does not cover cross country CL of the Doha Declaration

Possible impact of FTA on domestic manufacturers Main features of the local industries
Mainly conventional dosage form Limited capacity for production of raw materialsLimited capacity on bioavailability studies
Potential benefits of FTA: improve standard and quality increase export opportunities (AFTA, BIMST-EC) opportunity for cheaper raw material
Negative impact of FTA: reduce government’s revenueDisappear or being taken over longer period of expensive innovative drugs

Recommendation for alternative negotiation positions for Thai-US FTA
Main position: zero negative public health implication
Rationales: Current patent system has already allowed
13.4 to 18.8 year of market exclusivity- very long.
Additional public burden from market exclusivity is very high (may double health expense)
Accept TRIPS plus means amendment of related laws which also benefit all other trade partners
![Page 14: Possible Impact of Market Exclusivity Extension on Pharmaceuticals in Thailand Chutima Akaleephan International Health Policy Program, Thailand 27 August](https://reader030.vdocuments.us/reader030/viewer/2022032723/56649d195503460f949eec6c/html5/thumbnails/14.jpg)
Alternative position: least public health implications
No or shortest market exclusivity extension Case by case basis on compensation for delayed patent
registration and market authorization Compulsory licensing in such condition as national
emergency and extreme emergency must be retained Prevention of abuse in the implementation of linkage
between drug registration and patent
![Page 15: Possible Impact of Market Exclusivity Extension on Pharmaceuticals in Thailand Chutima Akaleephan International Health Policy Program, Thailand 27 August](https://reader030.vdocuments.us/reader030/viewer/2022032723/56649d195503460f949eec6c/html5/thumbnails/15.jpg)
Measures to alleviate the possible future negative implication
Improvement of the patent registration process and database close coordination between Department of IP and FDA reevaluation of patent of new use of drug closely monitor potential evergreening patent with heavy penalty easy search of IP database expert in pharmaceutical and/or chemistry could play important
role in examination of patent application
Support more R&D capacity of domestic manufactures
Promotion of rational drug use and generic substitution
Support further improvement of GMP to international qualification
