u-blox wins at Chinese Supreme Court against Techtotop in patent infringement suit

Thalwil, Switzerland – November 9, 2023 – u-blox (SIX:UBXN), a global provider of leading positioning and wireless communication technologies and services, has announced that the Chinese Supreme Court has ruled in favor of u-blox in a patent infringement claim filed by Techtotop Microelectronic Technology Co. Ltd. (TTT). The decision overturned a first instance ruling of the court in Guangzhou, China.

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.”
