What this shows TSE's Innovation Score is 48.7/100 (top 16% 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 TSE?

Each dot is one of TSE’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). TSE’s own 11.9 claims/patent is at or below the 18.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where TSE's grants concentrate

TSE Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 89.5% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2020. By volume, TSE sits between Transocean Innovation Labs Ltd. and TVWorks, LLC.

TSE's three-year grant acceleration

TSE Co., Ltd. shows 11 grants in 2022–2024 against only 3 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.
