What this shows PAI's Innovation Score is 36.7/100 (top 46% 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 PAI?

Each dot is one of PAI’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). PAI’s own 7.6 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PAI's grants concentrate

PAI Lung Machinery Mill Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under D04B (Knitting). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2015. By volume, PAI sits between Orca Security Ltd. and Pexip AS.

PAI's three-year grant acceleration

PAI Lung Machinery Mill Co., Ltd. shows 6 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.
