What this shows Cleanvolt's Innovation Score is 31.1/100 (36th percentile 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 Cleanvolt?

Each dot is one of Cleanvolt’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). Cleanvolt’s own 17.2 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cleanvolt's grants concentrate

Cleanvolt Energy, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under H01G (CAPACITORS; Capacitors, Rectifiers, Detectors, Switching Devices, Light-sensitive OR Temperature-sensitive Devices OF THE Electrolytic Type). By volume, Cleanvolt sits between Clarke Industrial Engineering Inc. and Clearview AI, Inc..

Cleanvolt's three-year grant acceleration

Cleanvolt Energy, Inc. shows 1 grants in 2022–2024 against only 1 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.
