What this shows Xiamen's Innovation Score is 33.8/100 (46th 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 12.9 claims/patent is at or below the 15.3 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 Institute OF Rare Earth Materials is a focused PatentsView assignee: 12 CPC subclasses with 42.9% of grants classified under Y02P (Climate Change Mitigation Technologies IN THE Production OR Processing OF Goods). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2017. By volume, Xiamen sits between X-rite Europe GMBH and Xped Holdings PTY Ltd.

Xiamen's three-year grant acceleration

Xiamen Institute OF Rare Earth Materials shows 3 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.
