What this shows Cambridge's Innovation Score is 37.4/100 (top 44% 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 13.4 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cambridge's grants concentrate

Cambridge International, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 65% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2024. By volume, Cambridge sits between Cambria County Association FOR THE Blind AND Handicapped and Center of Human-Centered Interaction for Coexistence.

Cambridge's three-year grant acceleration

Cambridge International, Inc. shows 8 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.
