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 10.7 claims/patent is at or below the 15.1 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 United Tools Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 38.1% of grants classified under B25B (Tools OR Bench Devices NOT Otherwise Provided FOR, FOR Fastening, Connecting, Disengaging OR Holding). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2019. By volume, Hangzhou sits between Heriot-watt University and Heritage Research Group, LLC.
Hangzhou's three-year grant acceleration
Hangzhou United Tools Co., Ltd. shows 12 grants in 2022–2024 against only 4 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.
