What this shows Hangzhou's Innovation Score is 33.0/100 (43rd 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 Hangzhou?
Each dot is one of Hangzhou’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). Hangzhou’s own 2.2 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Hangzhou's grants concentrate
Hangzhou Baiyu Technology Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 16.7% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2023 (4 grants) versus a trough of 2 in 2024. By volume, Hangzhou sits between Hamworthy Combustion Engineering Limited and Harbor MedTech, Inc..
Hangzhou's three-year grant acceleration
Hangzhou Baiyu Technology Co., Ltd. shows 6 grants in 2022–2024 against only 0 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.
