New Avenue for Accelerated Patent Examination in Vietnam

Subscribe to Updates
Tilleke & Gibbins

In October 2015, the National Office of Intellectual Property of Vietnam (NOIP) signed its first Patent Prosecution Highway (PPH) agreement with the Japanese Patent Office (JPO) to enable accelerated patent examination. The PPH will be implemented on a trial basis beginning on April 1, 2016. During the test period, the number of requests under the PPH will be limited to 100 per year.

At present, there are two accelerated examination procedures available in Vietnam. Firstly, the standard procedure requires an applicant to file a request for accelerated examination. In practice, in addition to the request, the applicant needs to receive the approval of the responsible examiner for an accelerated examination on a case-by-case basis. The NOIP will accept or refuse the request depending on the results of a quick assessment of patentability, and the NOIP’s backlog.

Requests are typically only accepted under the following circumstances:

  1. A highly reputable patent office such as the EPO, JPO, or USPTO has allowed the corresponding patent; and
  2. The applicant agrees to file a preliminary amendment to conform the claims of the Vietnamese application to the granted claims of the corresponding foreign patent.

As the backlog is usually large, the NOIP tends to refuse such requests.

The second procedure is the ASEAN Patent Examination Cooperation (ASPEC) program. An applicant can file a request under the ASPEC program if:

  1. The Vietnamese application links to one or more applications filed in the other participating patent offices (Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, the Philippines, Singapore, or Thailand) by one or more priority applications; and
  2. A search report and an examination report have been issued by any of the other participating patent offices, and at least one claim is considered to be allowable in accordance with the examination report.

When such a request is filed, the examination processes at the NOIP can be advanced out of turn for the patent application in question.

However, Vietnamese examiners have been reluctant to rely on the examination results of smaller, less experienced ASEAN patent offices. As stated above, Vietnamese examiners tend to pay greater deference to the examination results of large patent offices such as the EPO, JPO, USPTO, and SIPO, if available. Specifically, if a patent is granted by one of the large patent offices on a corresponding application, examiners would suggest the applicants to conform their application to the granted patent. If the application is thus amended, a Vietnamese patent will soon be granted on the application. As a result, the ASPEC program so far has not been as effective as hoped. Few requests have been submitted so far.

As the two existing procedures have had limited effectiveness, the PPH may be a route to meet the increasing needs of applicants who wish to obtain patents quickly, and may also help to reduce the backlog at the NOIP and improve the quality of examination.

Hopefully, the PPH will work well and will be expanded after the trial period, so that more and more PPH requests per year can be accepted by the NOIP. If the Japan-Vietnam PPH is successful, it is believed that the NOIP will consider signing additional PPHs with other patent offices.

In the meantime, practitioners in Vietnam continue to proactively contact examiners to inform them when corresponding patents are granted abroad and offer to conform to the granted patents in seeking  the acceleration of patents informally.

Modern agricultural machinery is no longer purely mechanical but instead technology dependent. Modern tractors, harvesters, and other farm equipment increasingly incorporate embedded software, electronic control units, sensors, and digital diagnostic systems. While such technologies enhance efficiency, productivity, and precision farming, they also affect the manner of equipment repair and maintenance. As a result, farmers and independent repair providers may have little practical choice but to rely on authorized dealers, even for routine maintenance and repairs. Section 36 of Thailand’s Patent Act reflects the principle that the authorized sale of a patented invention usually exhausts the exclusive right of the patent owner over the specific product. This means that upon legal sale of the patented product, it can typically be used or resold without further authorization from the patent holder. This principle is relatively straightforward when applied to traditional mechanical equipment. Ownership of a machine ordinarily carries with it the practical ability to diagnose faults, replace worn parts, and restore the equipment to working order. Modern agricultural machinery, however, increasingly depends on embedded software, proprietary diagnostic systems, firmware updates, and other digital resources that may remain under the control of the manufacturer or patent holder. This tension lies within the “right to repair” debate. In the United States, on July 8, 2026, the Federal Trade Commission and five states announced a settlement with Deere & Company resolving allegations that Deere had unlawfully restricted farmers’ and independent repair providers’ ability to repair their equipment. Under the terms of the settlement, for the next ten years, Deere must provide repair resources, including software capabilities, on terms equivalent to those provided to authorized dealers. The Deere settlement highlights that the nature of ownership is changing, but legal concepts have not kept pace. Traditional patent-law concepts, including patent exhaustion, were developed with physical products

Thailand has finalized its social media KYC (“know your customer”) rules under Notification of the Electronic Transactions Commission on Measures to Prevent Technological Crimes for Social Media Service Providers (No. 2), which was published in the Government Gazette on May 5, 2026, and will take effect on November 1, 2026. While an early draft of the notification proposed requiring social media platforms to arrange identification of every user account, the final notification is significantly more targeted, focusing on paid online advertising and advertiser identity verification. Though the regulatory initiative primarily aims to combat online fraud and technology-related crimes, it also has important consequences for intellectual property enforcement, because the verified platform records that will be generated under the new requirements can help IP rights holders to identify anonymous online infringers. Key Regulatory Mandates The notification requires social media service providers to verify the identity of advertisers before their paid advertisements are published and disseminated in Thailand through social media, regardless of whether the advertising fees come from the advertisers or third parties. Verification of an advertiser is valid for one year, after which verification would have to be performed again before the platform could publish additional paid advertisements from the advertiser. Permitted verification methods are specified under the notification. A platform may verify an advertiser by checking identity evidence and confirming the connection between the advertiser and that identity evidence, with the notification giving facial comparison against certain government-issued identity documents as an example. Alternatively, platforms may verify advertisers through a digital identity verification and authentication system with an identity-proofing assurance level not lower than the level prescribed by Thailand’s Electronic Transactions Commission. The notification further requires platforms to retain only the advertiser’s information necessary to identify the advertiser, beginning from the start of the advertising activity and for

Introduction: A Trademark Paradox in Sustainable Packaging Walk into any Thai supermarket, and the label-free water bottle is no longer a novelty. Thailand’s packaging market, valued at approximately USD 15.68 billion in 2025, is shifting toward minimalist, plastic-light designs as ESG pressures reshape how brands present their products. The country generated roughly 5.68 million tons of plastic waste in 2021, with a recycling rate of only 19 percent, and regulators are now considering rules that would allow label-free bottled water relying on embossing, laser printing, or QR codes instead of wrap-around labels. As packaging itself becomes the brand identifier, a paradox emerges: designs built to say the least often struggle hardest for protection under Thai intellectual property law. The Trademark Barrier: When Shape Is Not Enough Section 7, paragraph 2(10) of the Thai Trademark Act deems a shape distinctive only if it is not the natural form of the goods, is not necessary to achieve a technical result, and does not add value to the goods. The Department of Intellectual Property’s 2022 examination guidelines apply this test conservatively, as the following examples illustrate. A plain water bottle relying on subtle contours to signal its brand is typically read as just another bottle, not a source identifier. Acquired distinctiveness offers a theoretical escape route, but it demands extensive evidence of sales, advertising, and consumer recognition—an especially heavy burden for new entrants whose minimalist packaging has not yet achieved market prominence. The result is a structural bias against precisely the design innovation that sustainability goals are meant to encourage. Design Patents: A Partial, Imperfect Substitute Design patent protection, covering a product’s shape, configuration, or ornamentation, appears to offer an alternative route. In practice, it is constrained by the same forces driving the minimalist trend. Because many brands converge on similar solutions—clear
