What this shows PHA's Innovation Score is 31.8/100 (39th 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 PHA?

Each dot is one of PHA’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). PHA’s own 16.2 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where PHA's grants concentrate

PHA Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under E05Y (Indexing Scheme Associated With Subclasses E05d AND E05f, Relating TO Construction Elements, Electric Control, Power Supply, Power Signal OR Transmission, User Interfaces, Mounting OR Coupling, Detail). By volume, PHA sits between Perry + Currier Inc. and Phenix Systems.

PHA's three-year grant acceleration

PHA Co., Ltd. shows 1 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.
