What this shows Metawater's Innovation Score is 39.6/100 (top 38% 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 Metawater?

Each dot is one of Metawater’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). Metawater’s own 9.4 claims/patent is at or below the 10.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Metawater's grants concentrate

Metawater Co., Ltd. is a focused PatentsView assignee: 23 CPC subclasses with 75.8% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2020 (5 grants) versus a trough of 2 in 2016. By volume, Metawater sits between Mapa GMBH and Moynat Paris SAS.

Metawater's three-year grant acceleration

Metawater Co., Ltd. shows 8 grants in 2022–2024 against only 11 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.
