What this shows Nuvolta's Innovation Score is 44.5/100 (top 25% 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 Nuvolta?

Each dot is one of Nuvolta’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). Nuvolta’s own 17.4 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nuvolta's grants concentrate

NuVolta Technologies (Shanghai) Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 80% of grants classified under H02M (Apparatus FOR Conversion Between AC AND AC, Between AC AND DC, OR Between DC AND DC, AND FOR USE With Mains OR Similar Power Supply SYSTEMS; Conversion OF DC OR AC Input Power Into Surge Output POWER;). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2024. By volume, Nuvolta sits between NuCare, Inc. and Nurulize, Inc..

Nuvolta's three-year grant acceleration

NuVolta Technologies (Shanghai) Co., Ltd. shows 5 grants in 2022–2024 against only 0 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.
