The number of patent applications in Laos has steadily increased in recent years. In 2022, DIP received more than 200 patent applications, a 15% increase compared to 2021. The sectors with the most patent applications include healthcare, agriculture, and information technology. Patents help businesses create new, innovative and unique products and services, thereby improving competitiveness in the market. Patents also contribute to promoting innovation, improving production and business efficiency and creating competitive advantages for enterprises.

    In Laos, a patent is defined as an official certificate issued by a state agency to protect new patents that have innovative progress and are capable of industrial application.

    • Official Deed: A patent is an official document issued by the government.
    • State agency: The Lao agency responsible for patents is usually the National Office of Intellectual Property (DIP) under the Ministry of Science and Technology.

    • Industrial applicability: The patent must have practical application in industry and can be manufactured or used for commercial purposes.

    To register a patent in Laos, the applicant’s patent must meet the following conditions:

    Novelty: The patent must be completely new and not yet made public anywhere in the world before filing a patent application. This means that it must not:

    • Description in printed publication
    • Disclosure during the public presentation
    • Known or used by others
    • Filing a patent application by someone else (except in certain specific cases)

    Industrial applicability: The patent must be capable of manufacturing or use in industry. This means that it must have practical application and be reproducible. It cannot be purely theoretical or on abstract scientific principles.

    Additional Notes:

    • Patent exclusion: Laos excludes certain types of patents from patent protection, such as scientific discoveries, mathematical methods, diagrams, rules and methods of performing mental acts, playing games or business, and treatments on the human or animal body.
    • Small Patents: Laos offers a separate option for utility initiatives with simpler requirements. These are called “small patents” and provide protection for minor improvements or modifications to existing technologies.

    In Laos, there are two main types of patents that you can apply for:

    • New: Do not make it public anywhere before applying.
    • Creative Progress: Not obvious to someone with a conventional degree in this field.
    • Industrial applicability: Can be produced or used in industry.

    Patent application in Laos

    To apply for a patent in Laos, the applicant needs to prepare a dossier that includes the following documents:

    Essential Records:

    • Patent application: This form can be downloaded from the website of the Lao Intellectual Property Office (DIP) (https://dip.gov.la/). The application form usually asks for details about the applicant, inventor, and patent information.
    • Detailed description of the patent: This document should clearly explain the technical features, functions and advantages of the patent. This text should be written in Lao, the official language of Laos.
    • Claims: These requirements determine the scope of protection that the applicant wants for his patent.

    Patent registration in Laos through PCT system

    What is a PCT system?

    The PCT system stands for  Patent Cooperation Treaty – an international treaty that aims to create a uniform process for filing international patent applications. The system is administered by  the World Intellectual Property Organization (WIPO) and has more than 150 countries involved, including Laos. Laos acceded to the Treaty on 14 June 2006

    Benefits of PCT system:

    • Time and cost savings: The PCT system allows applicants to file a single patent application for patent protection in multiple Treaty countries, instead of having to file a separate application in each country. This saves time, costs and administrative procedures.
    • Postponement of national filing deadline: When filing a PCT application, the applicant has an additional 30 months to decide which country the applicant wants to protect the patent. This is valuable time for the applicant to assess the commercial potential of the patent and prepare for the national filing.
    • Simplified Process: The PCT system uses a common set of rules and procedures for all participating countries, which simplifies the filing process and saves time for both the applicant and the national patent office.
    • Early Search Information: The International Patent Search Office and Written Opinion will provide the applicant with information about the novelty and patentability of the patent, helping the applicant make an informed decision about the national filing.
    • Strengthening international cooperation: The PCT system encourages international cooperation in the field of patents by creating a common platform for the exchange of information and sharing of experiences between countries.
    • Innovation support: PCT systems help promote innovation by reducing the procedural burden on inventors and making it easier for them to protect their patents worldwide.
