What this shows Dongguan's Innovation Score is 48.8/100 (top 16% 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 15.4 claims/patent is ABOVE the 11.7 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 Leader Precision Industry Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 94.4% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2022 (10 grants) versus a trough of 2 in 2021. By volume, Dongguan sits between Dentlytec G.P.L. Ltd. and DeGen Medical, Inc..

Dongguan's three-year grant acceleration

Dongguan Leader Precision Industry Co., Ltd. shows 14 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.
