What this shows PI's Innovation Score is 53.4/100 (top 9% 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 PI?

Each dot is one of PI’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). PI’s own 11.2 claims/patent is at or below the 13.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PI's grants concentrate

PI Advanced Materials Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 80% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2022. By volume, PI sits between Penthera Partners, Inc. and Purpose Co., Ltd..

PI's three-year grant acceleration

PI Advanced Materials Co., Ltd. shows 12 grants in 2022–2024 against only 3 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.
