What this shows Oatey's Innovation Score is 59.6/100 (top 4% 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 Oatey?

Each dot is one of Oatey’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). Oatey’s own 10.9 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Oatey's grants concentrate

Oatey Co. is a focused PatentsView assignee: 27 CPC subclasses with 18.6% of grants classified under E03F (SEWERS; Cesspools). Peak complete grant year is 2024 (17 grants) versus a trough of 3 in 2015. By volume, Oatey sits between National University Corporation Kumamoto University and Outward, Inc..

Oatey's three-year grant acceleration

Oatey Co. shows 39 grants in 2022–2024 against only 13 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.
