Does more volume mean deeper claims for Qualigen?
Each dot is one of Qualigen’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). Qualigen’s own 10.5 claims/patent is at or below the 12.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Qualigen's grants concentrate
Qualigen Inc. is a focused PatentsView assignee: 11 CPC subclasses with 50% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2015. By volume, Qualigen sits between Pure Global Brands, Inc. and Quora, Inc..
Qualigen's three-year grant acceleration
Qualigen Inc. shows 3 grants in 2022–2024 against only 5 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.
