What this shows Tokyo's Innovation Score is 40.1/100 (top 36% 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 Tokyo's grants concentrate

Tokyo Rope MFG. Co., Ltd. is a focused PatentsView assignee: 32 CPC subclasses with 32.4% of grants classified under D07B (Ropes OR Cables IN General). Peak complete grant year is 2018 (11 grants) versus a trough of 1 in 2016. By volume, Tokyo sits between TGW Logistics GmbH and Telect, Inc..

Tokyo's three-year grant acceleration

Tokyo Rope MFG. Co., Ltd. shows 8 grants in 2022–2024 against only 13 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.
