Does more volume mean deeper claims for Daewoo?
Each dot is one of Daewoo’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). Daewoo’s own 11.8 claims/patent is at or below the 16.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Daewoo's grants concentrate
Daewoo Shipbuilding & Marine Engineering Co., Ltd. is a focused PatentsView assignee: 39 CPC subclasses with 68.1% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2016 (12 grants) versus a trough of 3 in 2021. By volume, Daewoo sits between Cameron Health, Inc. and Edge 3 Technologies.
Daewoo's three-year grant acceleration
Daewoo Shipbuilding & Marine Engineering Co., Ltd. shows 16 grants in 2022–2024 against only 17 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.
