Does more volume mean deeper claims for Chien?

Each dot is one of Chien’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). Chien’s own 2.6 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chien's grants concentrate

Chien Yu Hong Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 33.3% of grants classified under B25B (Tools OR Bench Devices NOT Otherwise Provided FOR, FOR Fastening, Connecting, Disengaging OR Holding). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2020. By volume, Chien sits between Check Video LLC and Chongqing Maiyi Technology Co., Ltd.

Chien's three-year grant acceleration

Chien Yu Hong Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
