What this shows ZEN's Innovation Score is 31.8/100 (39th 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 ZEN?

Each dot is one of ZEN’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). ZEN’s own 11.8 claims/patent is at or below the 13.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ZEN's grants concentrate

ZEN Design Solutions Limited is a focused PatentsView assignee: 10 CPC subclasses with 63.6% of grants classified under A45D (Hairdressing OR Shaving Equipment ; Equipment FOR Cosmetics OR Cosmetic Treatments, e.g. FOR Manicuring OR Pedicuring). Peak complete grant year is 2016 (9 grants) versus a trough of 1 in 2019. By volume, ZEN sits between Watt Fuel Cell Corp. and Zume, Inc..

ZEN's three-year grant acceleration

ZEN Design Solutions Limited shows 1 grants in 2022–2024 against only 5 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.
