What this shows Denki's Innovation Score is 46.9/100 (top 20% 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 Denki?

Each dot is one of Denki’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). Denki’s own 10.2 claims/patent is at or below the 20.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Denki's grants concentrate

Denki Kagaku Kogyo Kabushiki Kaisha is a focused PatentsView assignee: 39 CPC subclasses with 46.9% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2015 (29 grants) versus a trough of 1 in 2017. By volume, Denki sits between Convergent Dental, Inc. and Elite Electronic Material (KUNSHAN) Co., Ltd..

Denki's three-year grant acceleration

Denki Kagaku Kogyo Kabushiki Kaisha shows 1 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.
