Two patents are protected exclusively, which is the invention "Spherical mirror optics for medium wave thermal imaging equipment" born in 2017, solving the problem of self-study, designing and manufacturing the camera core, reducing minimize dependence on imports from abroad and the invention of “Method for making high-temperature synthetic materials” helps to produce materials that can meet the harsh working conditions in the military field.

These are both inventions of the Viettel Aerospace Institute (VTX), a member of the Military Industry and Telecommunications Group. Thus, it can be seen that the patents protected exclusively in the US have demonstrated Viettel's autonomous capacity in 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, US-issued patents are considered a valuable reference base in case it is necessary to register a patent in another country.

Currently, the number of Viettel's inventions is increasing, covering both military and civil fields, affirming the position of technological pioneer, aiming to become the core of building Viettel's high-tech defense corporation. Up to now, Viettel has been granted 56 patents in Vietnam and 11 patents granted by USPTO in the US.

Previously, in January 2022, the United States Patent and Trademark Administration (USPTO) also recognized the US Patent for 2 inventions of Viettel High-Tech Industry Corporation (Viettel High-Tech Industry Corporation (Viettel) VHT), Viettel Group is a wide-band dual polarized antenna and a large zoom ratio continuous zoom medium wave infrared lens.

The invention "Wideband Dual Polarized Antenna" gives an antenna scheme with compact structure, wide bandwidth sufficient for high-speed information processing, and "High-zoom ratio continuous zoom mid-wave infrared lens" offers built-in observation features with a range of tens of kilometers, providing high-contrast images in a variety of harsh conditions.
