What this shows China's Innovation Score is 41.8/100 (top 32% 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 China?

Each dot is one of China’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). China’s own 10.6 claims/patent is at or below the 11.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where China's grants concentrate

China Wonderland Nurserygoods Co., Ltd is a focused PatentsView assignee: 3 CPC subclasses with 35.7% of grants classified under B62B (Hand-propelled Vehicles, e.g. Hand Carts OR PERAMBULATORS; Sledges). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2022. By volume, China sits between Certis Cisco Security PTE Ltd and Claas Industrietechnik GmbH.

China's three-year grant acceleration

China Wonderland Nurserygoods Co., Ltd shows 13 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.
