What this shows Jiangsu's Innovation Score is 46.7/100 (top 20% 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 Jiangsu?

Each dot is one of Jiangsu’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). Jiangsu’s own 8.3 claims/patent is at or below the 9.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Jiangsu's grants concentrate

Jiangsu Leuven Instruments Co. Ltd is a focused PatentsView assignee: 11 CPC subclasses with 47.1% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2024 (8 grants) versus a trough of 1 in 2020. By volume, Jiangsu sits between Invitae Corporation and Jace Medical, LLC.

Jiangsu's three-year grant acceleration

Jiangsu Leuven Instruments Co. Ltd shows 12 grants in 2022–2024 against only 3 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.
