What this shows Hefei's Innovation Score is 50.1/100 (top 13% 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 Hefei?

Each dot is one of Hefei’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). Hefei’s own 18.1 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hefei's grants concentrate

Hefei Core Storage Electronic Limited is a focused PatentsView assignee: 4 CPC subclasses with 97% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2023 (12 grants) versus a trough of 1 in 2019. By volume, Hefei sits between Homag GmbH and IHI Charging Systems International GmbH.

Hefei's three-year grant acceleration

Hefei Core Storage Electronic Limited shows 23 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.
