What this shows Hefei's Innovation Score is 51.6/100 (top 11% 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 14.6 claims/patent is at or below the 16.0 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 Heating & Ventilating Equipment Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 83.3% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2021. By volume, Hefei sits between Haptech, Inc. and Horsch Leeb Application Systems GmbH.

Hefei's three-year grant acceleration

Hefei Midea Heating & Ventilating Equipment Co., Ltd. shows 9 grants in 2022–2024 against only 2 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.
