What this shows Toray's Innovation Score is 50.9/100 (top 12% 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 Toray?

Each dot is one of Toray’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). Toray’s own 9.6 claims/patent is at or below the 15.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Toray's grants concentrate

Toray Advanced Materials Korea Inc. is a focused PatentsView assignee: 39 CPC subclasses with 32.4% of grants classified under B01D (Separation). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2016. By volume, Toray sits between The Steelstone Group LLC and Universidade DO Porto.

Toray's three-year grant acceleration

Toray Advanced Materials Korea Inc. shows 11 grants in 2022–2024 against only 7 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.
