What this shows North's Innovation Score is 51.3/100 (top 12% 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 7.5 claims/patent is ABOVE the 6.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where North's grants concentrate

North China University of Science and Technology is a focused PatentsView assignee: 25 CPC subclasses with 30.8% of grants classified under Y02P (Climate Change Mitigation Technologies IN THE Production OR Processing OF Goods). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2016. By volume, North sits between NexTier Completion Solutions Inc. and Novian Health, Inc..

North's three-year grant acceleration

North China University of Science and Technology shows 8 grants in 2022–2024 against only 2 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.
