What this shows Dcseng's Innovation Score is 32.3/100 (41st 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 Dcseng?

Each dot is one of Dcseng’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). Dcseng’s own 6.9 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dcseng's grants concentrate

Dcseng Co. Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 87.5% of grants classified under B23B (TURNING; Boring). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2017. By volume, Dcseng sits between Datafeel Inc. and Defence Therapeutics Inc..

Dcseng's three-year grant acceleration

Dcseng Co. Ltd. shows 3 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.
