What this shows Teijin's Innovation Score is 47.7/100 (top 18% 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 Teijin?

Each dot is one of Teijin’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). Teijin’s own 11.2 claims/patent is at or below the 12.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Teijin's grants concentrate

Teijin Frontier Co., Ltd. is a focused PatentsView assignee: 40 CPC subclasses with 68% of grants classified under D10B (Indexing Scheme Associated With Sublasses OF Section D, Relating TO Textiles). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2015. By volume, Teijin sits between T Stamp Inc. and THE Parallax Group International, LLC.

Teijin's three-year grant acceleration

Teijin Frontier Co., Ltd. shows 10 grants in 2022–2024 against only 9 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.
