What this shows Dewertokin's Innovation Score is 59.6/100 (top 4% 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 Dewertokin?

Each dot is one of Dewertokin’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). Dewertokin’s own 13.0 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dewertokin's grants concentrate

Dewertokin Technology Group Co., Ltd. is a focused PatentsView assignee: 28 CPC subclasses with 62.8% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2022 (12 grants) versus a trough of 1 in 2020. By volume, Dewertokin sits between Chongqing University Of Posts And Telecommunications and Elektrobit Automotive GmbH.

Dewertokin's three-year grant acceleration

Dewertokin Technology Group Co., Ltd. shows 27 grants in 2022–2024 against only 8 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.
