Learn more about Patent

Thailand has multiple bilateral agreements with other countries allowing foreigners to file patents in Thailand. A patent can be defined as an industrial property title that gives the company that owns it a right to exploit, but more importantly a right to prohibit any other entity from exploiting the same patent. It is an exclusive title to an invention, granted to a person or company. It protects an invention against reproduction and exploitation of the design without its author. To exploit a new process or device, a patent must be accompanied by a right of exploitation. It supports innovative companies by protecting their advances, even if the validity is limited in time.

Why file a patent in Thailand?

Patenting is essential to preserve and protect an invention which gives the applicant the power to use their creation. Once a patent is filed, the applicant becomes the owner of the patent and has the right to use it for a limited period. Filing a patent confers the following benefits on the applicant:

Foreign investors doing business in developing countries such as Thailand often bring proprietary technologies that they want to protect, maintain their competitive advantage and get a return on their investment in research and development.

Patent rights allow innovations to be protected for a limited period of time. Therefore, a patent consists of exclusive rights granted to the inventor for a limited period of time in exchange for the end of exploitation, disclosure and use of the patent by the general public. In general, the application must include a description of the invention and one or more claims that define the invention.

Following the first fall in a decade in 2019, global patent filing activity increased in 2020, owing to a decline in China. China’s Intellectual Property Office reported another year of growth in 2020, with 1.5 million patent applications. This was 2.5 times greater than the patent office in the second most populous country, the United States (USPTO; 597,172). Japan (JPO; 288,472), the Republic of Korea (KIPO; 226,759), and the European Patent Office followed the United States (EPO; 180,346). These five offices accounted for 85.1 percent of the total worldwide.

Only three of the top ten offices – China (+6.9%), India (+5.9%), and the Republic of Korea (+3.6%) – witnessed an increase in applications in 2020, while Germany (–7.9%) and Japan (–6.3%) saw substantial losses.

Among the top ten offices were Germany (62,105), India (56,771), the Russian Federation (34,984), Canada (34,565), and Australia (29,294).

Thailand patent ip services

Due to long-term expansion in China as well as growing IP activity in other parts of Asia, Asian offices received two-thirds (66.6 percent) of all applications filed worldwide in 2020, up from 51.5 percent in 2010. North American offices accounted for nearly one-fifth (19.3%) of the global total, while European offices accounted for slightly over one-tenth (10.9 percent ). In 2020, Africa, Latin America and the Caribbean, and Oceania had a combined share of 3.2 percent of all workplaces. Around five out of ten IP applications were in Asia a decade ago; last year, the number reached close to seven out of ten IP applications.

In terms of filings outside of the United States, U.S.-based applicants filed the most similar applications abroad (226,297) in 2020, followed by Japan (195,906), Germany (99,791), China (96,268), and the Republic of Korea (96,268). (80,133).

In 2020, the number of active patents will have increased by 5.9% to roughly 15.9 million. The United States has the most patents in force (3.3 million), followed by China (3.1 million), Japan (2 million), the Republic of Korea (1.1 million), and Germany (1.1 million) (0.8 million).

China had the highest growth rate in patents in force in 2020 (+14.5%), followed by Germany (+8.1%), the United States (+6.9%), and the Republic of Korea (+4.6%). In 2020, Japan reported a minor drop (0.7 percent).

Computer technology was the most frequently featured technology in published patent applications worldwide in 2019 (the latest year for which complete data is available due to the delay between confidential application and publication), with 284,146 published applications, followed by electrical machinery (210,429), measurement (182,612), digital communication (155,011), and medical technology (154,706).

What are the different patents?

Thai law protects 3 types of patents which are:

➤ Patents for new products or processes benefiting from a period of protection of 20 years (non-renewable)
➤ Minor patents for new insignificant inventions benefiting from 10 years of protection (non-renewable)
➤ The patents on the model concern the aesthetic aspect of the shape, configuration or a model benefiting from the protection of 10 years (non-renewable)

Thus, small patents can protect their new inventions for up to 10 years (non-renewable). Decorative or aesthetic aspects of patented design articles, including features related to shape, configuration or pattern, can also be patented and protected for 10 years (non-renewable).

What can a patent not protect?

The following are not eligible for protection in Thailand:

➤ Microorganisms that are found in nature or any substance extracted from animals or plants
➤ Scientific or mathematical rules and theories
➤ Computer programs (protected by copyright)
➤ Diagnostic, treatment or remedy process used to cure human or animal diseases
➤ Inventions, contrary to public order or good morals, public health, or well-being

What are the conditions for filing a patent?

Your invention must meet several conditions to apply:

➤ Provide solutions to technical problems (technical standards)
➤ Provide new solutions (new rule)
➤ Lead to industrial applications
➤ Be creative (standard of creativity)

In practice, the invention does not have to be obvious to an innovation-minded scientist.

As a patent gives its holder a monopoly on the manufacture, sale and use of inventions, the conditions for obtaining protection can be complicated, especially for inventions. To obtain a patent, the invention must be new, industrially applicable and not obvious.

What are the required documents?

The applicant must provide the following supporting documents:

➤ Application form 001-Kor 2.2
➤ Name of the invention
➤ Technical field
➤ Summary of the invention
➤ Nature and object of the invention
➤ The disclosure
➤ Description of the drawings (if applicable)
➤ The best mode for carrying out the present invention

Does patent protect abroad?

No, your patent will only be protected on national territory. If you want to export your products or services abroad, you will have to adapt your protection. To do this, you can either file a national application in the country or countries you are targeting, or create a Community application, or file an international application.

How to apply for a patent?

1. Priority search: make sure that your invention is not already protected by a patent held by a third party. A lawyer can carry out this search.

2. Patent filing procedure: the formality can be done online. A lawyer must assist you. The filing procedure can take up to more than two years.

The application must then contain an abstract, a title, drawings supporting the description (if any) and claims. The claims must be clear and concise in order to identify the patentee’s exclusive rights in the invention. All of this information must be submitted in Thai to the Intellectual Property Department. The Thai translation of the corresponding foreign application (if any) is therefore crucial. Below is a simplified overview of the procedure for registering a national patent for an invention in Thailand.

3. Registration procedure: (national application – simplified) It is common for applications for inventions, especially applications without corresponding foreign use, to be examined within a period of about ten years. This is due to the backlog of pending applications in Thailand. The suspension of patents is a major concern in Thailand. While it will not discourage owners from filing applications in Thailand, it must be considered for enforcement reasons. Indeed, only granted applications could be enforced.

Can I protect an idea?

No. It is not possible for a simple idea because the criterion of industrial application will not be met. The application will therefore be refused by the Thai Intellectual Property Department. It is also impossible to file a patent for a concept.

How long is a patent?

The term is up to 20 years from the date of filing.

For your patent to be valid, the owner must pay royalties to the Thai Intellectual Property Department for the entire period of protection. Once this period has elapsed, the patented invention falls into the public domain: it is no longer protected and anyone can use it.
