The record first. Published December 14, 2023, US20230402853A1 (CPC H02J 7/00045 and H02J 50/12). Named inventors include Kyungmin Lee and Dongzo Kim. This is a published application. The claim has the device support fast charging delivered wirelessly — combining the speed consumers want from wired charging with the convenience of a pad.
Follow the attach loop. Wired fast charging and wireless charging have historically been separate accessory categories with separate purchases. Fusing them — fast charging on the pad — lets a maker sell a single, premium charging proposition: buy our device and our certified fast-wireless pad, and get speed plus convenience. That bundle deepens accessory attach.
The business framing is ecosystem capture. Each charging accessory the maker can fence and certify is margin captured inside its channel rather than ceded to third parties. Combining fast and wireless raises the value of the accessory and the switching cost of leaving the ecosystem. The publication is a maker building that combined loop.
Comparability discipline applies. "Charging" spans wired-fast, standard-wireless, and the emerging fast-wireless category; they have distinct accessory economics. The publication pins this claim to fast-wireless — useful for tracking the fusion of accessory categories, and a reminder that a publication is a position, not a grant.
What the document does not disclose is the economics. It is a device claim, not an accessory P&L. It will not tell you pad attach, accessory margin, or certification revenue. It establishes a fused-charging position; the financial stakes are undisclosed.
For investors, the throughline is this: makers grow accessory margin by fusing categories into one attach loop, and the patent record shows which are combining fast and wireless charging to do it.
