What this shows Dongwoon's Innovation Score is 43.4/100 (top 28% 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 Dongwoon?

Each dot is one of Dongwoon’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). Dongwoon’s own 7.4 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dongwoon's grants concentrate

Dongwoon Anatech Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 37.5% of grants classified under G03B (Apparatus OR Arrangements FOR Taking Photographs OR FOR Projecting OR Viewing THEM; Apparatus OR Arrangements Employing Analogous Techniques Using Waves Other Than Optical WAVES; Accessories Therefor). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2016. By volume, Dongwoon sits between Dice Corporation and Dräger Medical GmbH.

Dongwoon's three-year grant acceleration

Dongwoon Anatech Co., Ltd. shows 9 grants in 2022–2024 against only 4 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.
