What this shows Cambridge's Innovation Score is 28.5/100 (27th 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 Cambridge?

Each dot is one of Cambridge’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). Cambridge’s own 12.0 claims/patent is ABOVE the 10.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cambridge's grants concentrate

Cambridge Heatwear Limited is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). By volume, Cambridge sits between CalPortland Company and Camposol S.A..

Cambridge's three-year grant acceleration

Cambridge Heatwear Limited shows 2 grants in 2022–2024 against only 2 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.
