What this shows Ecoflow's Innovation Score is 40.6/100 (top 35% 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 Ecoflow?

Each dot is one of Ecoflow’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). Ecoflow’s own 8.3 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ecoflow's grants concentrate

Ecoflow Inc. is a focused PatentsView assignee: 4 CPC subclasses with 36.4% 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 (6 grants) versus a trough of 3 in 2022. By volume, Ecoflow sits between E8 Storage Systems Ltd. and Effect Photonics B.V..

Ecoflow's three-year grant acceleration

Ecoflow Inc. shows 9 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.
