Does more volume mean deeper claims for King?

Each dot is one of King’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). King’s own 7.8 claims/patent is at or below the 12.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where King's grants concentrate

King Roof Industrial Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 76.9% of grants classified under B60R (Vehicles, Vehicle Fittings, OR Vehicle Parts, NOT Otherwise Provided FOR). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2023. By volume, King sits between Kavo Dental Technologies, LLC and Kiran Jewels Inc..

King's three-year grant acceleration

King Roof Industrial Co., Ltd. shows 1 grants in 2022–2024 against only 8 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.
