What this shows Fujikura's Innovation Score is 53.2/100 (top 9% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Fujikura?

Each dot is one of Fujikura’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). Fujikura’s own 7.2 claims/patent is at or below the 14.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fujikura's grants concentrate

Fujikura Kasei Co., Ltd. is a focused PatentsView assignee: 27 CPC subclasses with 40% 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 2016 (6 grants) versus a trough of 1 in 2018. By volume, Fujikura sits between Fortune Brands Water Innovations LLC and Gaps Technology, LLC.

Fujikura's three-year grant acceleration

Fujikura Kasei Co., Ltd. shows 6 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.
