When will Xiaomi release its much-awaited flagship smartphone, the Mi 5? It may come in the next couple of months and hit the stores in several countries across the globe but it is expected to face trouble in the United States owing to patent infringement lawsuit filed against the company.

A firmed called Blue Spike LLC has sued Xiaomi Technology Co Ltd alleging that it has infringed US Patent No 8,930,719 (the "719 Patent" or "Patent-in-Suit") titled "Data Protection Method and Device", according to the complaint (via GSM Arena).

Xiaomi devices listed in the patent infringement complaint are Mi 4, Mi 4 LTE, Mi 4c, Mi 4i, Mi Note Plus, Mi Note Pro, Redmi 1S, Redmi 2, Redmi 2 Prime, Redmi 2 Pro, Redmi 2A, Redmi Note 2 and the upcoming Mi 5 and Mi 5 Plus.

Out of these, the Mi 4 and Redmi 2 have already received Federal Communications Commission (FCC) certification, but the rest haven't, which may come to the United States late or not be released at all.

It is reported that the Xiaomi Mi 5 and Mi 5 Plus will be unveiled in January 2016 and released on 8 February, but nothing is confirmed as of now. It has been in news since July that it would be launched in August before being shifted to September and November but it never happened.

According to reports, the flagship smartphone will sport sport a 5.2-inch QHD touchscreen with 2560 x 1440 pixel screen resolution and protected by Gorilla Glass 4. It may come with features like fingerprint sensor and Type-C USB port and priced at around $399 (approximately Rs 26,500). It is also expected to have Qualcomm Snapdragon 820 processor, Android 5.1.1 Lollipop, 32/64 GB internal memory, 4 GB RAM, 16 MP main camera with optical Image stabilization (OIS), 5 MP secondary snapper and 3,000mAh battery.
