Does more volume mean deeper claims for Kusumoto?

Each dot is one of Kusumoto’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). Kusumoto’s own 7.0 claims/patent is at or below the 11.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kusumoto's grants concentrate

Kusumoto Chemicals, Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under C09D (Coating Compositions, e.g. Paints, Varnishes OR LACQUERS; Filling PASTES; Chemical Paint OR INK REMOVERS; INKS; Correcting FLUIDS; WOODSTAINS; Pastes OR Solids FOR Colouring OR PRINTING; USE OF Materi). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2016. By volume, Kusumoto sits between Kulcloud and Kyowa Leather Cloth Co., Ltd..

Kusumoto's three-year grant acceleration

Kusumoto Chemicals, Ltd. shows 2 grants in 2022–2024 against only 1 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.
