What this shows North's Innovation Score is 35.5/100 (top 49% 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 North?

Each dot is one of North’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). North’s own 6.2 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where North's grants concentrate

North China Electric Power University (Baoding) is a focused PatentsView assignee: 12 CPC subclasses with 20% of grants classified under F01D (Non-positive Displacement Machines OR Engines, e.g. Steam Turbines). By volume, North sits between Noname Gate Ltd. and Northwest Biotherapeutics, Inc..

North's three-year grant acceleration

North China Electric Power University (Baoding) shows 2 grants in 2022–2024 against only 1 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.
