Patent landscape of satellite navigation
The paper describes patent landscape of the GPS-GLONASS satellite navigation created with use the international patent resource Qustel-Orbit. The inventions based on the use of GPS-GLONASS, have a wide range of applications. The greatest number of patents in this field was published in China, United States and Korea. Russia occupies the eleventh position in this ranking. A new approach to positioning the patent holders is proposed on the base of the following indicators: the number of patent families and the similarity of patent portfolio of patenters. The example of the positioning patent holders in the field of GPS-GLONASS on the territory of the Russian Federation is brought.
