What this shows Dorai's Innovation Score is 31.8/100 (39th 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 Dorai?

Each dot is one of Dorai’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). Dorai’s own 9.5 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dorai's grants concentrate

Dorai Home Inc. is a focused PatentsView assignee: 9 CPC subclasses with 33.3% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, Dorai sits between Digital Dream Labs, Inc. and Dynalloy, Inc..

Dorai's three-year grant acceleration

Dorai Home Inc. shows 3 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.
