What this shows Kenwood's Innovation Score is 34.9/100 (49th 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 Kenwood?

Each dot is one of Kenwood’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). Kenwood’s own 8.2 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kenwood's grants concentrate

Kenwood Limited is a focused PatentsView assignee: 14 CPC subclasses with 59.1% of grants classified under A47J (Kitchen EQUIPMENT; Coffee MILLS; Spice MILLS; Apparatus FOR Making Beverages). Peak complete grant year is 2015 (13 grants) versus a trough of 1 in 2016. By volume, Kenwood sits between Ictk Holdings Co., Ltd. and Lancium LLC.

Kenwood's three-year grant acceleration

Kenwood Limited shows 6 grants in 2022–2024 against only 11 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.
