What this shows Kyowa's Innovation Score is 46.5/100 (top 21% 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 10.3 claims/patent is at or below the 11.9 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 Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2016. By volume, Kyowa sits between Kyntec Corporation and Kanagawa Academy of Science and Technology.

Kyowa's three-year grant acceleration

Kyowa Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
