What this shows Cambridge's Innovation Score is 45.5/100 (top 23% 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 24.3 claims/patent is ABOVE the 17.8 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 Research & Instrumentation, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Cambridge sits between Caliber, Inc. and CardioKinetix, Inc..

Cambridge's three-year grant acceleration

Cambridge Research & Instrumentation, Inc. shows 2 grants in 2022–2024 against only 0 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.
