What this shows Dongguan's Innovation Score is 23.3/100 (12th 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 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 5.2 claims/patent is at or below the 16.8 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 Zhengyang Electronic Mechanical Co. Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 16.7% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2016 (7 grants) versus a trough of 1 in 2017. By volume, Dongguan sits between Distance Technologies Oy and DuPont Specialty Materials Korea Ltd..

Dongguan's three-year grant acceleration

Dongguan Zhengyang Electronic Mechanical Co. Ltd. shows 1 grants in 2022–2024 against only 5 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.
