Does more volume mean deeper claims for Quantumdx?
Each dot is one of Quantumdx’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). Quantumdx’s own 18.1 claims/patent is ABOVE the 12.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Quantumdx's grants concentrate
Quantumdx Group Limited is a focused PatentsView assignee: 8 CPC subclasses with 57.1% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2016. By volume, Quantumdx sits between Protomet Corporation and QuickLogic Corporation.
Quantumdx's three-year grant acceleration
Quantumdx Group Limited shows 5 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.
