Does more volume mean deeper claims for Daeyoung?
Each dot is one of Daeyoung’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). Daeyoung’s own 4.3 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Daeyoung's grants concentrate
Daeyoung Chaevi Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 37.5% of grants classified under B60L (Propulsion OF Electrically-propelled Vehicles ; Supplying Electric Power FOR Auxiliary Equipment OF Electrically-propelled Vehicles ; Electrodynamic Brake Systems FOR Vehicles IN General ; Magnetic SU). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2021. By volume, Daeyoung sits between D Three Enterprises, LLC and Data Accelerator Ltd.
Daeyoung's three-year grant acceleration
Daeyoung Chaevi Co., Ltd. shows 5 grants in 2022–2024 against only 3 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.
