What this shows Kwantex's Innovation Score is 22.2/100 (10th 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 Kwantex?

Each dot is one of Kwantex’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). Kwantex’s own 7.5 claims/patent is at or below the 11.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kwantex's grants concentrate

Kwantex Research Inc. is a focused PatentsView assignee: 5 CPC subclasses with 62.5% 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 2019 (3 grants) versus a trough of 1 in 2018. By volume, Kwantex sits between KTI Hydraulics Inc. and Kyoeisha Chemical Co., Ltd..

Kwantex's three-year grant acceleration

Kwantex Research Inc. shows 1 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.
