What this shows CET's Innovation Score is 33.6/100 (45th 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 CET?

Each dot is one of CET’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). CET’s own 8.2 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CET's grants concentrate

CET Limited is a focused PatentsView assignee: 6 CPC subclasses with 33.3% of grants classified under G03G (ELECTROGRAPHY; ELECTROPHOTOGRAPHY; Magnetography). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2021. By volume, CET sits between CEO Vision, Inc and CH Biomedical (USA) Inc..

CET's three-year grant acceleration

CET Limited shows 2 grants in 2022–2024 against only 1 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.
