What this shows Sanhua's Innovation Score is 47.0/100 (top 20% 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 Sanhua?

Each dot is one of Sanhua’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). Sanhua’s own 14.3 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sanhua's grants concentrate

Sanhua (HANGZHOU) Micro Channel Heat Exchanger Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 91.5% of grants classified under F28F (Details OF Heat-exchange AND Heat-transfer Apparatus, OF General Application). Peak complete grant year is 2016 (8 grants) versus a trough of 1 in 2015. By volume, Sanhua sits between Roche Innovation Center Copenhagen A/S and SEG Automotive Germany GmbH.

Sanhua's three-year grant acceleration

Sanhua (HANGZHOU) Micro Channel Heat Exchanger Co., Ltd. shows 12 grants in 2022–2024 against only 8 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.
