Does more volume mean deeper claims for Kmew?

Each dot is one of Kmew’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). Kmew’s own 3.9 claims/patent is at or below the 8.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kmew's grants concentrate

Kmew Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 20% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2023 (6 grants) versus a trough of 2 in 2015. By volume, Kmew sits between Kingsand Machinery Ltd. and Kofulso Co., Ltd.

Kmew's three-year grant acceleration

Kmew Co., Ltd. shows 6 grants in 2022–2024 against only 0 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.
