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 12.9 claims/patent is at or below the 17.1 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 Littelfuse Electronics Company Limited is a focused PatentsView assignee: 6 CPC subclasses with 93.8% of grants classified under H01C (Resistors). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2019. By volume, Dongguan sits between DevFactory Fz-llc and Drew Technologies, Inc..

Dongguan's three-year grant acceleration

Dongguan Littelfuse Electronics Company Limited shows 6 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.
