What this shows Techwin's Innovation Score is 30.7/100 (35th 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 Techwin?

Each dot is one of Techwin’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). Techwin’s own 10.6 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Techwin's grants concentrate

Techwin Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 57.1% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Techwin sits between TBI Innovations, LLC and Teva Pharmaceuticals Australia PTY Ltd.

Techwin's three-year grant acceleration

Techwin Co., Ltd. shows 2 grants in 2022–2024 against only 6 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.
