What this shows POU's Innovation Score is 33.5/100 (45th 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 POU?

Each dot is one of POU’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). POU’s own 9.9 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where POU's grants concentrate

POU Chen Corporation is a focused PatentsView assignee: 24 CPC subclasses with 75% of grants classified under A43D (Machines, Tools, Equipment OR Methods FOR Manufacturing OR Repairing Footwear). Peak complete grant year is 2019 (4 grants) versus a trough of 2 in 2021. By volume, POU sits between PML Screening, LLC and Presbyopia Therapies, Inc.

POU's three-year grant acceleration

POU Chen Corporation shows 2 grants in 2022–2024 against only 10 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.
