What this shows Sanwa's Innovation Score is 35.6/100 (top 49% 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 Sanwa?

Each dot is one of Sanwa’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). Sanwa’s own 11.1 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sanwa's grants concentrate

Sanwa Techno Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 36.4% 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 (3 grants) versus a trough of 1 in 2017. By volume, Sanwa sits between Samsung C & T Corporation and Sauder Woodworking Co..

Sanwa's three-year grant acceleration

Sanwa Techno Co., Ltd. shows 3 grants in 2022–2024 against only 3 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.
