U-blox wins Chinese patent case for M8 GNSS receivers
A global provider of leading positioning and wireless communication technologies and services, u-blox, has announced that the Chinese Supreme Court has ruled in favor of it in a patent infringement claim against Techtotop Microelectronic Technology Co. Ltd., (TTT) involving its M8 GNSS receivers.
In July 2021 the Hangzhou Intermediate People’s Court had already ruled that TTT had infringed on u-blox’s intellectual property in its TD1030 navigation chips and that TTT should pay damages (RMB 11 million). The dispute had started in 2019, when u-blox filed claims against TTT for both copyright and patent infringement after u-blox noticed similar functionalities of TTT’s TD1030 chip and corresponding modules with u-blox’s M8 GNSS (Global Navigation Satellite System) receivers. Following in-depth investigations, including reviews and analyses conducted by independent laboratories, u-blox had concluded that the similarities must have been the result of illegal copying of u-blox’s source code by Techtotop.
“It is for u-blox of the utmost importance to guarantee IP leadership and product quality,” stated Hamilton Chen, Country Manager, u-blox China. “Our technologies are the result of our commitment to continuous R&D, and our products are constantly tested to meet all quality requirements and applicable IP laws.”
Introduced in October, 2013, the u-blox M8 chip is able to acquire and track different satellite systems concurrently to achieve higher accuracy and reliability, including American GPS, European Galileo, Japanese QZSS, Russian GLONASS, and Chinese BeiDou satellites.
Concurrent tracking of GPS (QZSS) and GLONASS or BeiDou, or concurrent tracking of GLONASS and BeiDou satellites increases performance for applications requiring maximum availability and accuracy.
M8 chips feature low power consumption in concurrent reception mode, thanks to an innovative single-die architecture combined with sophisticated software algorithms. Sophisticated radio architecture and interference suppression using active jamming detection ensure maximum performance even in GNSS hostile environments.
