Does more volume mean deeper claims for Dongin?

Each dot is one of Dongin’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). Dongin’s own 10.6 claims/patent is ABOVE the 7.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dongin's grants concentrate

Dongin Optical Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2020. By volume, Dongin sits between Dongguan Apac Biotechnology Co., Ltd. and Drymax Technologies, Inc..

Dongin's three-year grant acceleration

Dongin Optical 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.
