What this shows Toray's Innovation Score is 48.1/100 (top 17% 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 11.9 claims/patent is ABOVE the 9.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Toray's grants concentrate

Toray Engineering Co., Ltd. is a focused PatentsView assignee: 43 CPC subclasses with 27.5% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2019 (8 grants) versus a trough of 1 in 2016. By volume, Toray sits between Swarovski Aktiengesellschaft and The Ergo Baby Carrier, Inc..

Toray's three-year grant acceleration

Toray Engineering Co., Ltd. shows 12 grants in 2022–2024 against only 16 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.
