What this shows Dongguan's Innovation Score is 52.3/100 (top 10% 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 16.2 claims/patent is ABOVE the 15.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dongguan's grants concentrate

Dongguan NVT Technology Limited is a focused PatentsView assignee: 14 CPC subclasses with 85.7% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2018. By volume, Dongguan sits between Design Pool Limited and Driving Management Systems, Inc..

Dongguan's three-year grant acceleration

Dongguan NVT Technology Limited shows 7 grants in 2022–2024 against only 1 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.
