OnePlus Pad trademark hints a company's new venture

OnePlus has come a long way since it launched its first-ever "Flagship Killer" in 2014. Although it initially focused on smartphones, it has diversified its product portfolio to include accessories, both wired and wireless, a smart TV, and, most recently, a smartwatch. All throughout those changes, the one mobile device category that OnePlus hasn't touched is the standalone slate, something that might be changing soon if this recent trademark filing means anything.
