What this shows Hangzhou's Innovation Score is 32.2/100 (40th 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 5.6 claims/patent is at or below the 14.2 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 Biotest Biotech Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 26.7% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2022 (6 grants) versus a trough of 3 in 2021. By volume, Hangzhou sits between Gibbs Technologies Limited and Hongik University Industry-academia Cooperation Foundation.
Hangzhou's three-year grant acceleration
Hangzhou Biotest Biotech Co., Ltd. shows 13 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.
