What this shows Daikyo's Innovation Score is 32.1/100 (40th percentile 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 Daikyo?

Each dot is one of Daikyo’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). Daikyo’s own 5.9 claims/patent is at or below the 17.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daikyo's grants concentrate

Daikyo Seiko, Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 41.2% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2019. By volume, Daikyo sits between Consolidated Metco, Inc. and DataInfoCom USA, Inc..

Daikyo's three-year grant acceleration

Daikyo Seiko, Ltd. shows 6 grants in 2022–2024 against only 10 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.
