Does more volume mean deeper claims for 4DS?

Each dot is one of 4DS’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). 4DS’s own 23.2 claims/patent is ABOVE the 15.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where 4DS's grants concentrate

4DS Memory, Limited is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H10N (Electric Solid-state Devices NOT Otherwise Provided FOR). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2022. By volume, 4DS sits between 1st Defence Industries Ltd. and A LA Carte Media, Inc..

4DS's three-year grant acceleration

4DS Memory, Limited shows 2 grants in 2022–2024 against only 8 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.
