Changes Expected to Computer Program Patent Examination Guidelines in Vietnam

Subscribe to Updates

The era of Industry 4.0 has led to a dramatic increase in corresponding computer program invention patent filings in Vietnam. However, the current patent examination guidelines for inventions related to computer programs are quite brief and vague, which inevitably causes difficulties for patent examination. Therefore, in 2021, the Intellectual Property Office of Vietnam (IP Office) considered the necessity of amending the patent examination guidelines for inventions related to computer programs.

Currently, a computer program is excluded from patentability under Article 59.2 of the Law on Intellectual Property (IP Law). However, according to Article 5.8.2.5 of the patent examination guidelines issued on March 31, 2010, as amended on December 31, 2020 (hereinafter referred to as the 2010 Guidelines), an invention related to a computer program is eligible to mature into a granted patent if the claimed subject matter has technical features and/or produces a further technical effect going beyond the normal interactions between the software and the hardware.

From June 24 to December 31, 2021, the IP Office established a working group including members from the patent examination center, the legal and policy department, and experts from the Japan International Cooperation Agency (JICA) to detail the provisions under Article 5.8.2.5 in order to tackle the problem of “In what circumstances are applications related to computer programs patentable?” In December 2021, the preliminary guidelines for this problem were drafted in the form of an annex to the 2010 Guidelines. The group also consulted many local IP agents, state agencies, organizations, and individuals to improve the draft. On December 18, 2021, the IP Office organized an online meeting with IP agents and organizations to discuss the draft.

Basically, the draft does not make any significant changes in comparison with Article 5.8.2.5 of the 2010 Guidelines, but it adds more details. The draft visualizes the process of computer program patent applications as follows:

Formality Examination Stage:

Step 1. Does the subject matter contain technical features (hardware, data processing representing physical entities)? If not, it will be rejected (Article 59.2 of the IP Law).

Step 2. Is the subject matter named with a term like “computer program”, “computer program product”, or “signal-carrying program”? If so, it will be rejected (Article 5.8.2.5 of the 2010 Guidelines).

Substantive Examination Stage:

Step 3. Does the subject matter contain technical features producing a further technical effect? If not, it will be rejected (Article 5.8.2.5 of the 2010 Guidelines).

Similar to Article 5.8.2.5 of the 2010 Guidelines, any claims presented as “computer program”, “computer software”, “computer program/software product”, or “signal-carrying program” should be eliminated by the examiners. However, the draft also prescribes that, in the formality examination stage, there are three types of claims that could be accepted: a method performed by a computer for a purpose; a processing apparatus adapted to perform the method; or a computer-readable storage medium containing a computer program to perform the method.

In current practice, the troubles often arise during examination of inventions combining a computer program with a business method or a calculation method, making it necessary to consider comprehensively if the invention has any technical features, or if it produces a further technical effect going beyond the normal physical interactions between the software and the hardware. In the December 2021 draft of the annex, the IP Office’s approach in the formality examination stage has been sufficiently clarified, but the approach in the substantive examination stage still needs more explanation, especially more interpretation of examples of “further technical effect.” If the approach in the substantive examination stage is solved, the examination process will be accelerated.

It is expected that the amended guidelines will be released in the near future.

Tilleke & Gibbins recently assisted Bitmain, a leading manufacturer of cryptocurrency mining hardware, in successful cancellation action lawsuits against BITMAIN and ANTMINER trademarks that were unlawfully registered by a local party in Indonesia. Background Founded in 2013, Bitmain is a leading manufacturer of digital currency mining servers, marketed under their BITMAIN and ANTMINER brands. The company has maintained a strong global market share, with customers in over 100 countries and regions. In Indonesia, Bitmain has held the BITMAIN trademark registration in classes 35, 36, 41, and 42 since 2018. However, the company was unable to register the trademark in other classes because a local party had already registered the mark in the desired classes. Bitmain also discovered that their ANTMINER brand had been registered by the same local party, which impeded Bitmain’s application to register the ANTMINER trademark in Indonesia. Bitmain had been using these trademarks and products worldwide long before the local party’s registration in Indonesia, and had also secured trademark registrations in various countries. However, the local party exploited Indonesia’s first-to-file principle, securing the BITMAIN and ANTMINER trademarks before Bitmain could file. This was a classic example of trademark squatting, where a party registers a foreign trademark in a jurisdiction where the original owner has not yet filed, with the intent to profit from the brand’s success. Initial Approach Upon discovering that the local party had made these trademark applications, Bitmain found that one of these applications was still in the publication period. We advised and assisted Bitmain to file opposition against the application, but this opposition was subsequently refused because the local party had already obtained identical BITMAIN trademarks in other classes. Consequently, the application was registered in the Trademark Office database. Following the unfavorable opposition decision, we initially worked with Bitmain to seek a mutually

Vietnam is on the cusp of a major judicial reform with significant implications for intellectual property (IP) litigators. A draft law, expected to be passed in mid-2025, will restructure the court system into a three-tiered judicial hierarchy while retaining the current two-tiered trial structure. The reforms include the anticipated establishment of a specialized IP court and a reallocation of jurisdiction that may fundamentally change how and where IP disputes are resolved. From 63 to 34: Fewer Provinces, Fewer Courts – But Wider Reach Under the new model, the judiciary will be organized into three levels: (i) the Supreme People’s Court, with three newly established appellate courts in Hanoi, Da Nang, and Ho Chi Minh City, (ii) the 34 provincial-level People’s Courts (following a reduction from 63 provinces to 34 due to administrative consolidation), and (iii) a newly created tier of regional-level courts (tòa án khu vực) that will replace the existing district-level courts. Each regional court will encompass several district-level courts within a province. The number of regional courts in each province will be determined based on the number of districts following a planned reduction. While the number of provincial-level courts will decrease, the newly established regional-level courts will be granted expanded jurisdiction. Notably, these courts will have first-instance jurisdiction over a broad range of civil, commercial, and administrative matters. In criminal cases, they will handle offenses punishable by up to 20 years’ imprisonment, while more serious crimes will remain under the jurisdiction of provincial-level courts. For IP litigators, this likely means that first-instance cases, especially civil infringement disputes, will shift from the provincial level to the lower regional level. These regional courts will become the new battleground for IP enforcement. Same Two-Tier Adjudication, Different Game Board While the judicial structure is evolving, the core adjudicative framework remains unchanged:
