What this shows Grayl's Innovation Score is 34.7/100 (49th 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 Grayl?

Each dot is one of Grayl’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). Grayl’s own 12.0 claims/patent is at or below the 12.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Grayl's grants concentrate

Grayl Inc. is a focused PatentsView assignee: 6 CPC subclasses with 58.3% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2015. By volume, Grayl sits between Gmems Tech Shenzhen Limited and GT Medical Technologies, Inc..

Grayl's three-year grant acceleration

Grayl Inc. shows 6 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.
