What this shows U.s.'s Innovation Score is 41.7/100 (top 32% 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 U.s.?

Each dot is one of U.s.’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). U.s.’s own 9.1 claims/patent is at or below the 11.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where U.s.'s grants concentrate

U.S. Tsubaki Holdings, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 25% of grants classified under F16C (SHAFTS; Flexible SHAFTS; Elements OR Crankshaft MECHANISMS; Rotary Bodies Other Than Gearing ELEMENTS; Bearings). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, U.s. sits between Tyrolit—Schleifmittelwerke Swarovski AG & Co K.G. and Uchino Co., Ltd..

U.s.'s three-year grant acceleration

U.S. Tsubaki Holdings, Inc. shows 5 grants in 2022–2024 against only 1 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.
