What this shows Daikin's Innovation Score is 28.9/100 (29th 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 Daikin?

Each dot is one of Daikin’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). Daikin’s own 2.9 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Daikin's grants concentrate

Daikin Manufacturing Company, L.P. is a focused PatentsView assignee: 7 CPC subclasses with 25% of grants classified under F24H (Fluid Heaters, e.g. Water OR AIR Heaters, Having Heat-generating Means, e.g. Heat Pumps, IN General). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2022. By volume, Daikin sits between Dune Medical Devices Ltd. and Davro Products, Inc..

Daikin's three-year grant acceleration

Daikin Manufacturing Company, L.P. shows 4 grants in 2022–2024 against only 3 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.
