What this shows TPR's Innovation Score is 49.2/100 (top 15% 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 8.6 claims/patent is at or below the 17.6 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 Co., Ltd. is a focused PatentsView assignee: 34 CPC subclasses with 53.4% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). Peak complete grant year is 2024 (12 grants) versus a trough of 2 in 2015. By volume, TPR sits between Superior Essex International Inc. and Titan3 Technology LLC.

TPR's three-year grant acceleration

TPR Co., Ltd. shows 24 grants in 2022–2024 against only 17 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.
