u-blox notes that TTT has published a summary of a Guangzhou court decision, which has not been submitted to u-blox yet.

瑞士优北罗股份有限公司(u-blox AG,以下简称“u-blox”)注意到泰斗微电子科技有限公司(以下简称“泰斗微电子”)发布了一则有关广州法院判决的声明,u-blox至今未收到此判决。 

In case the Guangzhou court has ruled that a TTT patent was infringed by certain u-blox products, u-blox will appeal the decision immediately.  



In this case, u-blox customers should not be concerned about a first instance decision. According to Chinese law, the first instance decision is unenforceable and will remain unenforceable, unless the second instance’s decision (Chinese Supreme Court at Beijing) confirms the Guangzhou court’s decision. The supreme court will need time to review the arguments of both parties and ensure that its decision takes into account the facts and complies with the law. This process is time consuming and pursuant to past experiences of our lawyers, the supreme court’s written decision is not expected to be rendered prior to 2024.
