What this shows Claverham's Innovation Score is 35.5/100 (top 49% 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 Claverham?

Each dot is one of Claverham’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). Claverham’s own 12.0 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Claverham's grants concentrate

Claverham Limited is a focused PatentsView assignee: 23 CPC subclasses with 42.1% of grants classified under B64C (AEROPLANES; Helicopters). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2018. By volume, Claverham sits between China-euro Vehicle Technology Aktiebolag and Colt's Manufacturing IP Holding Company LLC.

Claverham's three-year grant acceleration

Claverham Limited shows 2 grants in 2022–2024 against only 13 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.
