What this shows PUC's Innovation Score is 25.5/100 (17th 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 PUC?

Each dot is one of PUC’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). PUC’s own 1.4 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PUC's grants concentrate

PUC Perfect Union Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 18.2% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2022. By volume, PUC sits between Progress Lighting, LLC and Pacbrake Company.

PUC's three-year grant acceleration

PUC Perfect Union Co., Ltd. shows 5 grants in 2022–2024 against only 5 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.
