What this shows Nippon's Innovation Score is 45.4/100 (top 23% 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 Nippon?

Each dot is one of Nippon’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). Nippon’s own 7.4 claims/patent is at or below the 11.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nippon's grants concentrate

Nippon Filcon Co., Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 75% of grants classified under D03D (Woven FABRICS; Methods OF WEAVING; Looms). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2019. By volume, Nippon sits between National Christmas Products LLC and Nagase ChemteX Corporation.

Nippon's three-year grant acceleration

Nippon Filcon Co., Ltd. shows 7 grants in 2022–2024 against only 4 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.
