What this shows Subtron's Innovation Score is 33.9/100 (46th 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 Subtron?

Each dot is one of Subtron’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). Subtron’s own 9.3 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 Subtron's grants concentrate

Subtron Technology Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 81.4% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). Peak complete grant year is 2016 (11 grants) versus a trough of 1 in 2020. By volume, Subtron sits between Schleuniger AG and THE Board OF Regents OF THE Nevada System OF Higher Education ON Behalf OF THE University OF Nevada, LAS Vegas.

Subtron's three-year grant acceleration

Subtron Technology Co., Ltd. shows 1 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.
