What this shows Princo's Innovation Score is 34.5/100 (48th 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 Princo?

Each dot is one of Princo’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). Princo’s own 13.8 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Princo's grants concentrate

Princo Corp. is a focused PatentsView assignee: 19 CPC subclasses with 46.2% of grants classified under G04G (Electronic Time-pieces). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2017. By volume, Princo sits between Power Roll Limited and Punch Powertrain PSA E-transmissions NV.

Princo's three-year grant acceleration

Princo Corp. shows 2 grants in 2022–2024 against only 8 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.
