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 imports.

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

Viettel’s patents are increasing over the years and cover both military and civilian fields, affirming its pioneering position in technology as it works to become a high-tech military-industrial group.

To date, Viettel has been granted protection for 56 patents in Vietnam and 11 patents in the US.
