Does more volume mean deeper claims for Zhejiang?
Each dot is one of Zhejiang’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). Zhejiang’s own 11.1 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Zhejiang's grants concentrate
Zhejiang Chint Electrics Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 95.1% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2019 (10 grants) versus a trough of 1 in 2015. By volume, Zhejiang sits between WESTFÄLISCHE WILHELMS-UNIVERSITÄT MÜNSTER and Alios Biopharma, Inc..
Zhejiang's three-year grant acceleration
Zhejiang Chint Electrics Co., Ltd. shows 11 grants in 2022–2024 against only 16 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.
