What this shows Ai4's Innovation Score is 44.8/100 (top 25% 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 Ai4?

Each dot is one of Ai4’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). Ai4’s own 14.5 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ai4's grants concentrate

Ai4 International Oy is a focused PatentsView assignee: 7 CPC subclasses with 50% of grants classified under G01S (Radio DIRECTION-FINDING; Radio NAVIGATION; Determining Distance OR Velocity BY USE OF Radio WAVES; Locating OR Presence-detecting BY USE OF THE Reflection OR Reradiation OF Radio WAVES; Analogous Arra). Peak complete grant year is 2023 (4 grants) versus a trough of 2 in 2022. By volume, Ai4 sits between Agot Co. and Air Innovations, Inc..

Ai4's three-year grant acceleration

Ai4 International Oy shows 6 grants in 2022–2024 against only 0 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.
