What this shows Kyowa's Innovation Score is 40.6/100 (top 35% 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 Kyowa?

Each dot is one of Kyowa’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). Kyowa’s own 13.6 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kyowa's grants concentrate

Kyowa Kirin Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 84.8% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2020 (8 grants) versus a trough of 2 in 2019. By volume, Kyowa sits between Keysight Technologies Singapore (SALES) Pte. Ltd. and Megadyne Medical Products, Inc..

Kyowa's three-year grant acceleration

Kyowa Kirin Co., Ltd. shows 20 grants in 2022–2024 against only 18 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.
