What this shows Inoac's Innovation Score is 49.2/100 (top 15% 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 Inoac?

Each dot is one of Inoac’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). Inoac’s own 10.2 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Inoac's grants concentrate

Inoac Corporation is a focused PatentsView assignee: 37 CPC subclasses with 40% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2021 (6 grants) versus a trough of 2 in 2019. By volume, Inoac sits between Hansen Medical, Inc. and Invention And Collaboration Laboratory Pte. Ltd..

Inoac's three-year grant acceleration

Inoac Corporation shows 11 grants in 2022–2024 against only 8 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.
