What this shows Dong's Innovation Score is 36.0/100 (top 48% 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 Dong?

Each dot is one of Dong’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). Dong’s own 12.6 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dong's grants concentrate

Dong Yang INK Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under C09D (Coating Compositions, e.g. Paints, Varnishes OR LACQUERS; Filling PASTES; Chemical Paint OR INK REMOVERS; INKS; Correcting FLUIDS; WOODSTAINS; Pastes OR Solids FOR Colouring OR PRINTING; USE OF Materi). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2022. By volume, Dong sits between Doddle & Co., LLC and Dongguan Boyi Furniture Co., Ltd..

Dong's three-year grant acceleration

Dong Yang INK Co., Ltd. shows 3 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.
