What this shows Principle's Innovation Score is 38.0/100 (top 42% 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 Principle?

Each dot is one of Principle’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). Principle’s own 21.4 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Principle's grants concentrate

Principle Power, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2015. By volume, Principle sits between Precise Biometrics AB and ProntoForms Inc..

Principle's three-year grant acceleration

Principle Power, Inc. shows 4 grants in 2022–2024 against only 4 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.
