In accordance with Article 59.2 of the Law on Intellectual Property issued in 2005, as amended and supplemented in 2009 and 2019 (“IP Law”), Vietnamese law currently does not recognize the protection of computer programs as inventions. However, in practice, if the subject-matter of an invention related to a computer program has technical characteristics and the program, when running on a computer, creates a further technical effect going beyond the usual physical interactions between a program and a computer, this subject-matter is likely to be protected as an invention. This condition is not codified, but is reflected in Article 5.8.2.5 of the patent examination guidelines issued in 2010, as amended and supplemented in 2020 – a reference document showing the guidance issued by the Intellectual Property Office of Vietnam (“IP Office”). Currently, at the formality examination stage, these “technical” conditions for inventions related to computer programs are quite easy to meet as it is only necessary to show that the subject-matter is a “Method performed by a computer for a purpose …”, “Processing apparatus…”, or “Computer-readable storage medium storing a program to perform the method…”. In the substantive examination stage, however, the “technical” condition is further scrutinized through the assessment of technical features stated in the subject-matter to determine whether the interaction between the program and the computer creates a further technical effect. The IP Office often issues office actions on substantive examination results because the computer-related patent application does not solve any technical problem and does not produce a further technical effect going beyond the normal interactions between the program and the computer. On December 31, 2021, the IP Office added to the patent examination guidelines mentioned above by issuing an annex with specific guidelines for examining patent applications
