What this shows KEM's Innovation Score is 31.4/100 (38th 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 KEM?

Each dot is one of KEM’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). KEM’s own 7.6 claims/patent is at or below the 10.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where KEM's grants concentrate

KEM Hongkong Limited is a focused PatentsView assignee: 11 CPC subclasses with 53.8% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2016. By volume, KEM sits between Jasper Technologies, Inc. and Koppe Royalty B.V..

KEM's three-year grant acceleration

KEM Hongkong Limited shows 5 grants in 2022–2024 against only 9 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.
