Does more volume mean deeper claims for Princeton?
Each dot is one of Princeton’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). Princeton’s own 21.8 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Princeton's grants concentrate
Princeton Biochemicals is a focused PatentsView assignee: 3 CPC subclasses with 69.2% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, Princeton sits between Post Consumer Brands, LLC and Promethium, Inc..
Princeton's three-year grant acceleration
Princeton Biochemicals shows 4 grants in 2022–2024 against only 4 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.
