What this shows North's Innovation Score is 43.8/100 (top 27% 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 5.7 claims/patent is at or below the 17.0 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 Institute Of Science And Technology is a focused PatentsView assignee: 14 CPC subclasses with 42.9% of grants classified under E21C (Mining OR Quarrying). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2022. By volume, North sits between Nobles Medical Technologies II, Inc. and Nottingham Spirk Design Associates.

North's three-year grant acceleration

North China Institute Of Science And Technology shows 5 grants in 2022–2024 against only 0 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.
