What this shows Tsudakoma's Innovation Score is 51.6/100 (top 11% 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.

Where Tsudakoma's grants concentrate

Tsudakoma Kogyo Kabushiki Kaisha is a focused PatentsView assignee: 22 CPC subclasses with 34.9% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2023 (11 grants) versus a trough of 1 in 2017. By volume, Tsudakoma sits between THE University OF Electro-communications and Unilumin Group Co., Ltd.

Tsudakoma's three-year grant acceleration

Tsudakoma Kogyo Kabushiki Kaisha shows 30 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.
