The first patent is a curved mirror optical system for medium wave thermal imaging devices that was created in 2017, addressing the problem of designing and manufacturing camera cores, thereby minimising import.

The second patent involves a method to manufacture composite materials that can withstand high temperatures and meet the harsh conditions of the military field.

The number of Viettel's inventions has been on the rise, covering both military and civil fields, affirming its position as a technological pioneer. Viettel has been granted 56 patents in Vietnam and 11 patents in the US by USPTO.

Patents protected exclusively in the US have demonstrated Viettel's autonomous capacity in the research and development of core technologies in high-tech production and manufacturing. The US is a leading country in the world in terms of technology. The US-issued patents are considered a valuable reference base in case it is necessary to register a patent in another country.

According to statistics from the National Office of Intellectual Property in 2021, Viettel is the technology firm having the largest number of patent applications and protected patents annually in Vietnam for 2021.

Recently, Viettel’s two projects in the military and defence fields were also awarded the HCM Prize - the highest award in science and technology.

Viettel Aerospace Institute (VTX) is under Viettel Group, established in 2017. VTX's mission is to research, design, and manufacture all kinds of high-tech equipment serving military and civil missions; cooperate with domestic and foreign partners in research and development of science and technology, building and training human resources in the field of aerospace. In February 2022 VTX was awarded First-class Fatherland Defense Order by the State President.
