What this shows Keya's Innovation Score is 48.4/100 (top 17% 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 Keya?

Each dot is one of Keya’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). Keya’s own 19.7 claims/patent is ABOVE the 6.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Keya's grants concentrate

Keya Medical Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 85.7% of grants classified under G06N (Computing Arrangements Based ON Specific Computational Models). Peak complete grant year is 2023 (4 grants) versus a trough of 3 in 2022. By volume, Keya sits between Kelheim Fibres GMBH and Kimberbell Kids, L.L.C..

Keya's three-year grant acceleration

Keya Medical Technology Co., Ltd. shows 7 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.
