What this shows AI's Innovation Score is 45.9/100 (top 22% 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 AI?

Each dot is one of AI’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). AI’s own 10.9 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where AI's grants concentrate

AI Speech Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 92.9% of grants classified under G10L (Speech Analysis Techniques OR Speech SYNTHESIS; Speech RECOGNITION; Speech OR Voice Processing TECHNIQUES; Speech OR Audio Coding OR Decoding). Peak complete grant year is 2023 (6 grants) versus a trough of 3 in 2024. By volume, AI sits between Adige S.P.A. and Akeso Biomedical, Inc..

AI's three-year grant acceleration

AI Speech Co., Ltd. shows 9 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.
