Does more volume mean deeper claims for Denso?

Each dot is one of Denso’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). Denso’s own 7.7 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Denso's grants concentrate

Denso Daishin Corporation is a focused PatentsView assignee: 7 CPC subclasses with 88.9% of grants classified under F02D (Controlling Combustion Engines). Peak complete grant year is 2024 (3 grants) versus a trough of 2 in 2021. By volume, Denso sits between Delk, Inc. and Deviceeng Co., Ltd..

Denso's three-year grant acceleration

Denso Daishin Corporation shows 7 grants in 2022–2024 against only 2 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.
