Blue Spike LLS has targeted Chinese smartphone giant Xiaomi in a patent infringement lawsuit.

Blue Spike's lawsuit against Xiaomi, filed in the United States District Court for the Eastern District of Texas, demands a jury trial. The patent troll alleges that Xiaomi infringed upon its U.S. patent 8,930,719 B2, which is named simply as "Data Protection Method and Device."

The patent troll said that Xiaomi is using the technology in the patent without its permission for the Mi 4, the Mi 4 LTE, the Mi 4c, the Mi 4i, the Mi Note Plus, the Redmi 1S, the Redmi 2, the Redmi 2 Prime, the Redmi 2A and the Redmi Note 2.

Interestingly though, the unannounced but already highly anticipated Mi 5 and Mi 5 Plus, Xiaomi's next flagship smartphones, are also named in the lawsuit.

According to Blue Spike, the company has legitimate businesses that revolve around its Address Space Layout Randomization, or ASLR, systems, software and technology. However, when searching through Google, results reveal that Blue Spike is indeed a patent troll as several other patent infringement lawsuits have been filed by the company. There was even a period over 15 days when Blue Spike filed lawsuits against a total of 45 companies.

The timing of Blue Spike's patent infringement lawsuit against Xiaomi obviously aims to capitalize on the pending announcement of the Mi 5, which is rumored to occur probably as soon as January 2016. The patent troll could be wishing that Xiaomi, instead of having to delay the launch of the Mi 5 due to legal issues, would simply pay up to settle the matter as quickly and hassle-free as possible.

Xiaomi CEO Lei Jun promised that the Mi 5 is "worth the wait" at an event held last month, where the company unveiled the Redmi 3 and Mi Pad 2. While no details have officially been revealed for the smartphone, it is believed that the Mi 5 will have a 5.3-inch quad HD display with 2,560 x 1,440 pixel resolution and powered by the Qualcomm Snapdragon 820 with a quad-core CPU, Adreno 530 GPU and 4GB of RAM.
