What this shows TPR's Innovation Score is 32.3/100 (41st 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 TPR?

Each dot is one of TPR’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). TPR’s own 11.0 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where TPR's grants concentrate

TPR Industry Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 76.9% of grants classified under F02F (Cylinders, Pistons OR Casings, FOR Combustion ENGINES; Arrangements OF Sealings IN Combustion Engines). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, TPR sits between Topura Co., Ltd. and TRC Services, Inc..

TPR's three-year grant acceleration

TPR Industry Co., Ltd. shows 3 grants in 2022–2024 against only 7 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.
