What this shows T.'s Innovation Score is 30.1/100 (33rd percentile 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 T.?

Each dot is one of T.’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). T.’s own 7.5 claims/patent is at or below the 13.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where T.'s grants concentrate

T. K. Chin Company Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 25% of grants classified under A63G (MERRY-GO-ROUNDS; SWINGS; ROCKING-HORSES; CHUTES; SWITCHBACKS; Similar Devices FOR Public Amusement). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, T. sits between Swift Fuels, LLC and Takeda GMBH.

T.'s three-year grant acceleration

T. K. Chin Company Ltd. shows 4 grants in 2022–2024 against only 6 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.
