Where's the white space? In 2022 wireless power, it was between the two crowds. The filing data splits into a consumer-electronics cluster and a vehicle cluster that barely touch each other, despite living in the same H02J 50 classes.
The consumer cluster is dense and concentrated. NuCurrent alone carries 91 filings in the facet; Apple, Logitech (US11355948B2), and Mojo Mobility (US11404909B2) fence off coil positioning, interference reduction, and heat management for phones and accessories. The emphasis is small-gap, low-power, high-volume.
The vehicle cluster is the other world: ABB's US11427095B2 (EV charging system), Raytheon's US11404910B2 (multi-cell array), and a long tail of automaker and supplier filings. Here the CPC emphasis shifts to B60L 53/12 and 53/122 (contactless vehicle charging), and the engineering problem is large-gap, high-power, tolerant-of-misalignment.
The strategic read: these are two distinct IP markets wearing the same classification. A consumer-device portfolio and an EV-charging portfolio rarely cite each other and rarely share assignees. The shared physics (inductive coupling) masks divergent commercial races — one for the phone on the desk, one for the car in the driveway.
The caveat this desk attaches to any landscape: one year, one CPC family, a mix of publications and grants. But the bimodal shape is robust — wireless power in 2022 was not one field consolidating, it was two fields running in parallel. For a grid-IP reader, the EV cluster is the one to watch, because dynamic and stationary vehicle charging is where wireless power actually touches the grid.
