What this shows Dongguan's Innovation Score is 39.9/100 (top 37% 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 Dongguan?

Each dot is one of Dongguan’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). Dongguan’s own 4.2 claims/patent is at or below the 4.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dongguan's grants concentrate

Dongguan DSP Technology Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 80% of grants classified under C25D (Processes FOR THE Electrolytic OR Electrophoretic Production OF COATINGS; ELECTROFORMING; Apparatus Therefor). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2022. By volume, Dongguan sits between Dong-a Teaching Materials Co., Ltd. and Dongguan JUN Shun Plastic Mold Co., Ltd..

Dongguan's three-year grant acceleration

Dongguan DSP Technology Co., Ltd. shows 3 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.
