What this shows Tosoh's Innovation Score is 53.0/100 (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 Tosoh?

Each dot is one of Tosoh’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). Tosoh’s own 11.9 claims/patent is ABOVE the 10.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Tosoh's grants concentrate

Tosoh Finechem Corporation is a focused PatentsView assignee: 29 CPC subclasses with 54.5% of grants classified under C07F (Acyclic, Carbocyclic OR Heterocyclic Compounds Containing Elements Other Than Carbon, Hydrogen, Halogen, Oxygen, Nitrogen, Sulfur, Selenium OR Tellurium). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2016. By volume, Tosoh sits between Tocalo Co., Ltd. and Truemotion, Inc..

Tosoh's three-year grant acceleration

Tosoh Finechem Corporation shows 12 grants in 2022–2024 against only 5 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.
