What this shows Zeng's Innovation Score is 28.3/100 (27th 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 Zeng?

Each dot is one of Zeng’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). Zeng’s own 9.2 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zeng's grants concentrate

Zeng Hsing Industrial Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 83.3% of grants classified under D05B (Sewing). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Zeng sits between You Map Inc. and Zhejiang Ausun Pharmaceutical Co., Ltd..

Zeng's three-year grant acceleration

Zeng Hsing Industrial Co., Ltd. shows 2 grants in 2022–2024 against only 6 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.
