What this shows Xiamen's Innovation Score is 21.5/100 (9th percentile 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 Xiamen?

Each dot is one of Xiamen’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). Xiamen’s own 8.7 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 Xiamen's grants concentrate

Xiamen Kingqueen Industrial Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2018. By volume, Xiamen sits between Xi'an YEP Telecommunication Technology, Ltd. and Xl-protein GMBH.

Xiamen's three-year grant acceleration

Xiamen Kingqueen Industrial Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
