What this shows Uchiyama's Innovation Score is 39.6/100 (top 38% 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 Uchiyama?

Each dot is one of Uchiyama’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). Uchiyama’s own 12.4 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Uchiyama's grants concentrate

Uchiyama Manufacturing Corp. is a focused PatentsView assignee: 26 CPC subclasses with 34.5% of grants classified under F16C (SHAFTS; Flexible SHAFTS; Elements OR Crankshaft MECHANISMS; Rotary Bodies Other Than Gearing ELEMENTS; Bearings). Peak complete grant year is 2019 (7 grants) versus a trough of 1 in 2015. By volume, Uchiyama sits between Titan Spine, LLC and Unlimiter MFA Co., Ltd..

Uchiyama's three-year grant acceleration

Uchiyama Manufacturing Corp. shows 4 grants in 2022–2024 against only 11 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.
