What this shows Pyeong's Innovation Score is 42.2/100 (top 31% 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 Pyeong?

Each dot is one of Pyeong’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). Pyeong’s own 13.6 claims/patent is ABOVE the 12.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Pyeong's grants concentrate

Pyeong Hwa Automotive Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 69.6% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2015. By volume, Pyeong sits between Precitec GmbH & Co. KG and Shanghai Xiaoyi Technology Co., Ltd..

Pyeong's three-year grant acceleration

Pyeong Hwa Automotive Co., Ltd. shows 18 grants in 2022–2024 against only 15 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.
