What this shows Dreame's Innovation Score is 47.9/100 (top 18% 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 Dreame?

Each dot is one of Dreame’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). Dreame’s own 8.3 claims/patent is at or below the 9.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dreame's grants concentrate

Dreame Innovation Technology (Suzhou) Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 33.3% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2024 (5 grants) versus a trough of 2 in 2022. By volume, Dreame sits between Dong Guan Bright Yinhuey Lighting Co., Ltd. China and Ebner Industrieofenbau GmbH.

Dreame's three-year grant acceleration

Dreame Innovation Technology (Suzhou) Co., Ltd. shows 9 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.
