What this shows Keeson's Innovation Score is 42.0/100 (top 32% 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 Keeson?

Each dot is one of Keeson’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). Keeson’s own 4.3 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Keeson's grants concentrate

Keeson Technology Corporation Limited is a focused PatentsView assignee: 11 CPC subclasses with 33.3% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2024 (8 grants) versus a trough of 1 in 2020. By volume, Keeson sits between Korea Institute OF Materials Science and Kompan A/S.

Keeson's three-year grant acceleration

Keeson Technology Corporation Limited shows 17 grants in 2022–2024 against only 7 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.
