What this shows Quzhou's Innovation Score is 35.8/100 (top 48% 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 Quzhou?

Each dot is one of Quzhou’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). Quzhou’s own 4.2 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 Quzhou's grants concentrate

Quzhou T-NineTools Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 20% of grants classified under F16B (Devices FOR Fastening OR Securing Constructional Elements OR Machine Parts Together, e.g. Nails, Bolts, Circlips, Clamps, Clips OR WEDGES; Joints OR Jointing). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2023. By volume, Quzhou sits between Quickbiz Holdings Limited, Apia and R.T.D. Enterprises.

Quzhou's three-year grant acceleration

Quzhou T-NineTools Co., Ltd shows 4 grants in 2022–2024 against only 0 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.
