What this shows CSI's Innovation Score is 20.0/100 (6th 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 CSI?

Each dot is one of CSI’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). CSI’s own 6.7 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CSI's grants concentrate

CSI Solar Power Group Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 33.3% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2023. By volume, CSI sits between Crystaphase International, Inc. and CT-Concept Technologie GmbH.

CSI's three-year grant acceleration

CSI Solar Power Group Co., Ltd. shows 1 grants in 2022–2024 against only 5 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.
