What this shows PPI's Innovation Score is 19.0/100 (5th 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 PPI?

Each dot is one of PPI’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). PPI’s own 3.1 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PPI's grants concentrate

PPI Pyungwha Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 30.8% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2021. By volume, PPI sits between Pochet DU Courval and Profoto AB.

PPI's three-year grant acceleration

PPI Pyungwha Co., Ltd shows 1 grants in 2022–2024 against only 7 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.
