What this shows Tf-metal's Innovation Score is 31.7/100 (39th 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 Tf-metal?

Each dot is one of Tf-metal’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). Tf-metal’s own 7.7 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tf-metal's grants concentrate

Tf-metal Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 95.8% of grants classified under B60N (Seats Specially Adapted FOR VEHICLES; Vehicle Passenger Accommodation NOT Otherwise Provided FOR). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2018. By volume, Tf-metal sits between Syqe Medical Ltd. and Thompson Surgical Instruments, Inc..

Tf-metal's three-year grant acceleration

Tf-metal Co., Ltd. shows 11 grants in 2022–2024 against only 10 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.
