What this shows Powermat's Innovation Score is 53.5/100 (top 9% 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 Powermat?

Each dot is one of Powermat’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). Powermat’s own 16.2 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Powermat's grants concentrate

Powermat Technologies Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 98.7% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2022 (15 grants) versus a trough of 3 in 2020. By volume, Powermat sits between Ninebot (BEIJING) Tech Co., Ltd. and SK ie technology Co., Ltd..

Powermat's three-year grant acceleration

Powermat Technologies Ltd. shows 27 grants in 2022–2024 against only 14 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.
