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 15.1 claims/patent is ABOVE the 4.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhejiang's grants concentrate

Zhejiang Sanhua Commercial Refrigeration Controls Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2023. By volume, Zhejiang sits between Zhejiang Ledison Optoelectronics Co., Ltd. and ZI YI Electrical Engineering Co., Ltd..

Zhejiang's three-year grant acceleration

Zhejiang Sanhua Commercial Refrigeration Controls Co., Ltd. shows 5 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.
