The list of companies that Blue Spike has filed lawsuits against for allegedly infringing on its patents is too long to say with a single breath, but just know that Xiaomi is the latest company to be added to that list. Whether or not the American company is a patent troll is a matter of opinion, but its numerous lawsuits definitely suggest as much, as does its arsenal of vague patents that it uses to launch these lawsuits. Blue Spike recently filed a lawsuit against Xiaomi for violating a patent related to IP protection, which it claims was used on most of Xiaomi’s smartphones, including two that have yet to be released.
