What rights did Xiaomi 6 infringe on Coolpad?

According to the information webpage links of domestic mainstream websites, Coolpad Group sued Xiaomi for six patent infringements of mobile phones. Xiaomi responded that legal documents had not been received at that time, but Coolpad Group immediately took out a formal litigation lawyer's letter and formally filed a civil lawsuit against Xiaomi for infringing six patents of Coolpad Group.

At the same time, the current CEO of Coolpad also said that Xiaomi's mobile phone infringed on nearly 200 patents of Coolpad Group, but now only six of them have filed lawsuits. At the same time, it is said that Coolpad Group and Qualcomm have cooperated in more than 10,000 patents, which are only allowed to be used by Qualcomm, but not by any third party.

Moreover, there are some patents for dual-card dual standby, which can't even be used in Qualcomm. However, in six lawsuits, there was no patent involving dual card dual standby. Therefore, some analysts believe that Coolpad's lawsuit is to make the industry pay attention to intellectual property rights, not to find trouble with Xiaomi.
