What this shows Ningbo's Innovation Score is 47.8/100 (top 18% 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 Ningbo?

Each dot is one of Ningbo’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). Ningbo’s own 2.2 claims/patent is at or below the 11.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ningbo's grants concentrate

Ningbo Tuotuo River Design Company is a focused PatentsView assignee: 12 CPC subclasses with 9.8% of grants classified under F16M (Frames, Casings OR Beds OF Engines, Machines OR Apparatus, NOT Specific TO Engines, Machines OR Apparatus Provided FOR ELSEWHERE; STANDS; Supports). Peak complete grant year is 2023 (23 grants) versus a trough of 1 in 2021. By volume, Ningbo sits between Moxa Inc. and OP Solutions, LLC.

Ningbo's three-year grant acceleration

Ningbo Tuotuo River Design Company shows 52 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.
