Does more volume mean deeper claims for Tokyo?

Each dot is one of Tokyo’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). Tokyo’s own 9.5 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tokyo's grants concentrate

Tokyo Parts Industrial Co., Ltd. is a focused PatentsView assignee: 28 CPC subclasses with 46.7% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2019 (9 grants) versus a trough of 1 in 2018. By volume, Tokyo sits between The Technology Partnership PLC and Trivver, Inc..

Tokyo's three-year grant acceleration

Tokyo Parts Industrial Co., Ltd. shows 4 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.
