What this shows Wi-charge's Innovation Score is 42.5/100 (top 30% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Wi-charge?

Each dot is one of Wi-charge’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Wi-charge’s own 13.9 claims/patent is ABOVE the 5.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wi-charge's grants concentrate

Wi-Charge Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 93.9% of grants classified under H04B (Transmission). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2015. By volume, Wi-charge sits between Woongjin Coway Co., Ltd. and Zensun (Shanghai) Science & Technology, Co., Ltd..

Wi-charge's three-year grant acceleration

Wi-Charge Ltd. shows 13 grants in 2022–2024 against only 8 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
