What this shows Hefei's Innovation Score is 55.8/100 (top 7% 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 12.0 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hefei's grants concentrate

Hefei Midea Refrigerator Co., Ltd. is a focused PatentsView assignee: 40 CPC subclasses with 64.8% of grants classified under F25D (REFRIGERATORS; Cold ROOMS; ICE-BOXES; Cooling OR Freezing Apparatus NOT Otherwise Provided FOR). Peak complete grant year is 2024 (17 grants) versus a trough of 2 in 2017. By volume, Hefei sits between Fujitsu Technology Solutions Intellectual Property GmbH and International Rectifier Corporation.

Hefei's three-year grant acceleration

Hefei Midea Refrigerator Co., Ltd. shows 31 grants in 2022–2024 against only 18 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.
