Xiaomi Sued For Alleged Patent Infringement Ahead of Blockbuster IPO (reuters.com)

An anonymous reader shares a report: Chinese smartphone maker Coolpad said its unit has sued three group firms of Xiaomi, which last week filed for a Hong Kong IPO that could be worth up to $10 billion, for patent infringement. Coolpad said in a statement late on Thursday its subsidiary, Yulong Computer Telecommunication Scientific (Shenzhen) filed a lawsuit against Xiaomi Telecom Technology, Xiaomi Technology and Xiaomi Factory in a court in Jiangsu province for using its patent without authorization. Yulong demanded that the Xiaomi companies should immediately stop production and sale of some smartphone models, including the Mi MIX2, Coolpad said.

The linked article doesn't have much detail: "Coolpad has alleged that Xiaomi violated its patented multi-simcard design and other technology related to user interface.".
It does seem like a last ditch effort of a failing company though "Coolpad shares have been suspended since March 2017. It has been unable to report its 2017 annual result on time and only just filed its 2016 annual report last month after repeated delays due to audit problems.". I already went further than usual by RTFA, so won't attempt to find better sources...
I doubt it is something of merit that would cause a problem, but at least I have my Mi Mix 2 :) Definitely best phone I've ever had (OK, best Android phone, I still have a soft-spot for the Meego/Maemo Nokia N9) - and far from the most expensive! Oh, and the first Xiaomi that supports all T-Mobile LTE bands, so works great even when I visit the US.
