What this shows Charles's Innovation Score is 40.9/100 (top 34% 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 Charles?

Each dot is one of Charles’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). Charles’s own 21.2 claims/patent is ABOVE the 16.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Charles's grants concentrate

Charles River Laboratories International, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). By volume, Charles sits between Change Up Inc. and ChemLink Laboratories, LLC.

Charles's three-year grant acceleration

Charles River Laboratories International, Inc. 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.
