What this shows Sinox's Innovation Score is 52.2/100 (top 10% 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 Sinox?

Each dot is one of Sinox’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). Sinox’s own 10.0 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sinox's grants concentrate

Sinox Company Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 80.6% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2019. By volume, Sinox sits between Sanuwave, Inc. and Swiss Krono Tec AG.

Sinox's three-year grant acceleration

Sinox Company Ltd. shows 16 grants in 2022–2024 against only 5 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.
